1 Background
The Corrib gas field lies in around 350m of water approximately 65km off the coast of County Mayo. Gas from the field is to be brought ashore via a 20-inch subsea pipeline, which makes its landfall at Dooncarton in Broadhaven Bay. From there, the pipeline will be routed onshore to the terminal at Bellanaboy Bridge.
Installation of the export gas pipeline and its landfall were consented under Section 40 of the Gas Act. Several conditions were attached to that consent, including surveys of the sediments in Broadhaven Bay, which may be affected by the installation of the pipeline.
As part of the monitoring programme for the development, pre- and post-construction surveys of the nearshore environment were commissioned by SEPIL. Two pre- construction surveys were performed (2005 and 2008), before completion of pipeline installation works in September 2009. The first post-construction survey was completed 1 month after this in October 2009.
This report presents the findings of the survey undertaken in June 2010. The June 2010 survey fulfilled the requirements for a 6-month post-construction survey as well as the requirement to complete a survey in the same season as the pre-construction survey was completed (to allow comparison of pre and post construction conditions without season being an influence).
The installation of the pipeline was originally proposed for the summer of 2002, and a pre-construction survey of near-shore sediments along the proposed pipeline route was undertaken at that time. Thirty-six locations along the pipeline route through Broadhaven Bay were surveyed, with two additional reference stations being located to the north of the pipeline route (one off the coast from Rinnaglana, and one near Benwee Head) at the periphery of Broadhaven Bay. However, construction of the pipeline was delayed for a considerable period after this survey was completed, and it could therefore not be considered a ‘pre-construction’ survey for the revised construction schedule.
RSK Environment Ltd (RSK) was contracted by Shell E&P Ireland Ltd (SEPIL) to undertake the nearshore environmental monitoring programme (which includes the present 12-month post-construction survey). Following various delays, SEPIL planned to install the pipeline from the For inspection landfall purposes out only. to the Corrib field in summer 2008, and Consent of copyright owner required for any other use. consequently a second ’pre-construction‘ survey was undertaken in May 2008.
The installation works for the offshore pipeline were commenced and then suspended during summer 2008, and then successfully completed during summer 2009, with rock armouring of a nearshore section of the pipeline in Broadhaven Bay being completed in October 2009. Following the completion of pipeline installation works, a 1-month post- construction survey was undertaken in November by RSK.
This report details the second post-construction benthic monitoring survey, and was undertaken in June 2010. The rationale for sampling in the summer allows for a direct seasonal comparison with that of the pre-constrruction survey, which was undertaken in May 2008. This survey fulfils the monitioring survey conditions set out as per the Foreshore Licence conditions.
Table 1.1 summarises the nearshore surveys undertaken thus far as part of the pre and post-construction monitoring of the offshore pipeline in Broadhaven Bay.

2 Objectives and Rationale
The objectives of the 12-month post-construction survey are to monitor the physical and biological characteristics of the seabed of Broadhaven Bay following the installation of the Corrib export pipeline, and to compare the results obtained with the results from pre- and post-construction surveys.
Aspects to be sampled, and the rationale for their selection, are as per the 2008 pre- construction survey (RSK, 2009). The following briefly describes the parameters measured during the 12-month post-construction survey:
• Physico-chemical: Samples collected by Day grab, for the following analyses:
o Particle size analysis (PSA); and
o Total organic carbon (TOC). • Biological:
o Benthic infauna e.g. worms & bivalve molluscs: Collected by Day Grab, if sufficient replicate samples are taken, this can provide quantitative and statistically reliable data; and
o Epibiota (i.e. those organisms living on the seabed surface) sampled using drop-down stills and video photography to provide qualitative, broad-scale data on the presence of larger organisms (e.g. echinoderms, fish) as well as general ecological conditions (e.g. macroalgae, sediment bedforms, presence of bedrock).
The data collected will allow for the comparison of results from this survey and those obtained from the baseline surveys of 2002 (EcoServe, 2002) and 2008 (RSK, 2009) and the 1-month post-construction survey of 2009 (RSK, 2010). This comparison will help to determine if effects from the installation of the pipeline through Broadhaven Bay are apparent, and if they are, to what distance from the pipeline they extend.
As per the 2008 pre-construction baseline survey and the 1-month post-construction survey (2009), two reference For inspection stations purposes were only. selected that are geographically removed from the pipeline routeConsent through of copyright Broadhaven owner required Bay,for any butother areuse. likely to be subjected to similar
natural environmental influences, due to their proximity to the pipeline route. Any natural changes seen at the stations over the whole survey period will need to be considered in the overall review of whether project-specific impacts are discernible.
This 12-month post-construction survey followed a similar work-scope as the previous surveys, albeit with some minor revisions, which are detailed in Sections 2.1 and 4.1 .
2.1 Planned sampling regime
Data from grab and photographic sampling were to be collected from six transects crossing the nearshore pipeline route, each with 6 stations. These were selected so that data collected would be directly comparable to the results of previous studies (EcoServe, 2002; RSK, 2009; 2010).
Stations were located at a distance of 25, 50 and 500m away from the pipeline on both sides. These distances differ in this survey and the 1-month post construction survey from the pre-construction surveys, as concerns were raised regarding the proximity of seabed sampling equipment to the pipeline (which throughout much of Broadhaven Bay lies in an un-backfilled trench). As a result, stations 3 and 4 on each transect, originally at 10m distance from the pipeline (as sampled in 2008) were set back to 25m distance from the as-laid pipeline centre line.

3 Survey methods
3.1 Vessel
As per previous RSK surveys, the survey vessel used was the Nomad operated by Sinbad Marine Services. RSK provided navigational and survey personnel to undertake the work and all associated equipment. Positions were recorded as both UTM Grid and standard latitude and longitude positions (recorded in degrees, minutes and seconds, all in WGS84 datum). The target accuracy for positioning at benthic sample stations was within 10m of the proposed position. The specifications of the navigational equipment and the report of the navigation calibration check are presented in Appendix 1 .
3.2 Dates
Mobilisation of the Nomad in Killybegs harbour commenced on the 9 th June 2010 with the vessel arriving in Ballyglass that same evening. The first survey operations were performed on the 10 th June 2010. Survey work was attempted on the 11 th , but was weathered off site. Survey work continued on the 12 th , was not attempted on the 13 th and 14 th (due to the weather), and continued on the 15 th . Survey work was completed on the evening of the 16 th June, and the vessel and equipment were demobilised at Ballyglass. The Nomad transited back to Killybegs, arriving early in the morning on the 17 th June. 3.3 Grab sampling
A Day grab was used for sediment sample collection. Three replicate samples were taken for macrofaunal analysis, while single samples were taken for analysis of physico- chemical parameters, at each station. Raw data is included as Appendix 2 of this report.
Position, date, time, water depth, sediment type and other details (colour, smell, vertical layering, redox discontinuity layer, visible biota, evidence of biological activity) were recorded upon retrieval of theFor inspection grab; apurposes digital only. photograph was also taken of the sample, Consent of copyright owner required for any other use. including a sample identification card. Between each deployment, the grab sampler was rinsed thoroughly and scrubbed clean to limit cross-contamination between sampling locations.
3.4 Drop-down photography
Seabed photography was acquired using a digital video/stills camera system with a lamp and strobe ( Figure 3.1). The camera system was deployed within a specially designed stainless-steel frame allowing the equipment to be used at individual drop- down locations or to be towed in a sledge-type configuration. The camera system was previously used during the 1-month post-construction survey and differed slightly from that used during the 2008 pre-construction survey, where a Simrad-Kongsberg OE14- 208 system was deployed.

Figure 3.1: Underwater camera equipment (BSL 3.4 megapixel system) The seabed video footage was displayed live on a monitor onboard the Nomad and recorded directly onto DVD. A navigation data string displaying position, date and time was overlaid on to the recorded footage. At each photographic location a number of high-definition still photographs were taken and their positions recorded, a log sheet was completed that included position, transect and station, time, date, and water depth.
The camera system could be deployed in a straight up and down “drop-down” capacity in the event that sea conditions meant that towing the sledge along the seabed was not possible. In addition, there was the option to fit a freshwater lens to allow photography under conditions of poor visibility at the seabed.

3.5 Sample processing
3.5.1 Physico-chemical A single grab sample collected at each station was sub-sampled for both particle size analysis and TOC from the surface 5cm depth of sediment using a disposable plastic spoon. The samples were double-bagged with a waterproof internal identification label inserted between the two bags, sealed and refrigerated before transfer under pre- established chain-of-custody procedures. Analysis was undertaken using accredited methods (UKAS (United Kingdom Accreditation Service) by Benthic Solutions Ltd. Descriptive sediment classifications based on proportions of gravel (>2mm), sand (2mm-63µm) and mud (<63µm) were determined based on the Udden-Wentworth grain size classification scheme (Wentworth, 1922) ( Figure 3.2 ).

At the end of the survey, the samples were transferred according to chain-of-custody procedures to the analytical laboratory (Hebog Environmental Ltd.) for taxonomy and enumeration.
3.5.3 Drop-down photography Seabed stills and video footage were reviewed and sediment type and any identifiable biota were recorded.

4 Results
4.1 Samples obtained
All grab samples were obtained successfully from their planned location, with the exception of the following :
• No grab samples at three stations (A1, B6 and C6) despite repeated grab deployments and subsequent slight relocation of sampling location. It was anticipated that samples would be unobtainable at these locations from earlier appraisal of the drop-down photography, from the vessels echo-sounder during the sampling, and as a result of a similar failure to obtain samples at the locations during the 2008 pre-construction survey and 1-month post construction survey. The unsuccessful sampling at these locations was as a result of the presence of harder substrate (bedrock and cobbles), evidence of which is shown in the images captured at these stations by the seabed photography ( Figure 4.1);
• Change of sample position one at one station (reference station # 2), despite a number of grab deployments, and despite the fact that sampling had been successful here previously (in 2008). Successful sampling was achieved from a slightly revised location approximately 500m to the west of the target location, at a point when the vessels echo sounder indicated that the seabed was suitable. The station was also re-located to the same position during the 1-month post construction survey.

Actual sampling locations are presented in Figure 4.2 and positions of sampled locations, distance from planned target, water depth, time and date are presented in the fix logs ( Appendix 4 ).
Due to the sea/wind conditions, it was not possible to accurately tow the video/stills camera sled at the seabed for the full length of each transect. The camera was instead deployed as a more conventional drop-down camera at each sampling station. Where possible the sea/wind and tidal conditions were assessed and the vessel allowed to drift across the station along the transect with the camera on the seabed. Deployment in this manner allowed for accurate positioning for stills photography at each sampling location, while recording as much video footage as possible.
Static fishing gear was deployed over some areas of the nearshore pipeline in Broadhaven Bay, which hampered certain aspects of the survey operations. These issues were overcome by working with the nearshore support vessels, provided by Belcross Enterprises, and no undue delays to the survey were incurred. Appendix 4 shows the target positions for the grab sampling and seabed photography as well as the actual locations surveyed.

4.2 Physico-chemical
Particle size analysis and TOC results for all stations are presented in Table 4.1.
4.2.1 Particle size Sediment from all of the stations successfully sampled is classified, based on the Udden-Wentworth grain size classification (as per Wentworth, 1922), as sand. In the vast majority of these stations gravel (>2mm) and mud (<63µm) fractions were absent and samples consisted entirely of sand (63µm-2mm). However, there was some spatial variation in the dominant size of sand grains present over the survey area.

Medium (250-500µm) and fine (125-250µm) sand dominated throughout the survey area, and constituted more than 70% of sediment material on all transects. In general, coarser sand (i.e. very coarse 1-2mm, and coarse sands 500-999µm) were more dominant at stations A3. A5 and A6) (near to the shore), and Transects E and F (furthest offshore). A lower proportion of coarse sand and a higher proportion of very fine sand (63µm-125µm) was recorded at station A2 and transects B, C & D, The results from transect A appears to show more of a range of sand fractions than other sampling stations. Mud (<63µm) was entirely absent from two of the six transects (B and F), and occurred at very low quantities (0.01%) at only 1 station on transect D. The highest recorded quantities of mud were found at the reference stations (2.34% at REF1 and 3.59% at REF2) and at station E5 (1.67%). Lower levels of mud were also found along transect C at <1%. Both reference stations also contained relatively high levels of very fine sand,

indicating slightly less mobile conditions than elsewhere in the survey area, with the possible exception of transects C and D.
Along any given transect, mean grain size and general sample composition was generally similar, with any exceptions to this usually occurring at the ends of a transect. Table 4.2 shows a summary of the PSA data for the 2010 12-month post-construction survey compared with that of the 2008 pre-construction survey and 2009 post construction survey. Overall, there is very little variation in median grain size and corresponding Udden-Wentworth sediment descriptions between surveys.

4.2.2 Total organic carbon (TOC) Table 4.3 presents the Total Organic Carbon (TOC) levels for the 2010 12-month post- construction survey compared with the levels in 2009 and the 2008 pre-construction survey. TOC values for the 2010 survey are generally low, and similar to those recorded in 2009. The 2010 values range between 0.02% at station F1 and 0.23% TOC at station D4. As levels of TOC are often positively associated with the percentage of fine material present, these data are as expected given the almost complete absence of mud in the survey area and the exposed, high-energy nature of this coastline.
The results are comparable with the levels recorded in the two preceding surveys, though the 2010 and 2009 results are generally slightly lower than that of 2008.

4.3 Benthic infauna
Raw benthic invertebrate count data are presented in Appendix 2 .
4.3.1 Univariate analysis Based on species identification and enumeration data from the benthic grab replicates, a number of univariate ecological indices were calculated per replicate and per station (i.e. all replicates pooled). Per station data are presented in Table 4.4; (note that encrusting and/or colonial species are included in the analysis for number of species per replicate/ station, but are excluded from abundance counts).
Species numbers and abundances were moderate to high at the majority of stations. Per site, the number of species per 0.1m 2 ranged from 18 at site A4 to 129 at reference station 2, whilst abundances (individuals per 0.1m 2) ranged from 44 at site A6 to 2645 at site D4 ( Table 4.4).

* For the 2010 post-construction surveys Ref station #2 was sampled at location Ref Station #2 West.
Table 4.4 shows the Shannon-Weiner diversity indices for each site (which incorporates overall species numbers, but also includes aspects of dominance etc) and shows that diversity is, with the exception of sites A4 and D4, moderate to high, ranging from 1.82 at site A5 to 3.51 at reference station # 2. Generally, diversity was highest further offshore, with most sites on transects D and E having diversity indices of more than 3. It should be noted that these values do not include encrusting species as they are calculated using abundance and species numbers.
This overall trend is to be expected; transect A is much more susceptible to environmental variables such as freshwater input and wave action, given its shallow water depth and proximity to land; like estuaries, these conditions normally support less diverse communities of more adaptable organisms. Moving further offshore into deepwater, the effect of these variables on organisms becomes less, allowing for more “stable” conditions and a more diverse community.
On the whole, communities had a high evenness and low dominance, but sites where diversity was less than 2 exhibited a lowered Pielou’s evenness index and increased Simpson’s dominance index. This was particularly evident at sites A4 and D4, which had a very low diversity of 1.18 and 1.02 respectively. Evenness at these sites was found to be low (<0.5) and dominance, by one or few species, high (>0.5).
Ranked taxa illustrating the 10 most abundant species at each site are shown in Table 4.5. No one phylum dominated the communities in the sampling area. However, there were similarities within each lettered group of sites; A and C sites were generally dominated by annelids (>50%), B sites had high contributions from both Annelida and Crustacea, E sites were dominated by molluscs and communities at sites on transect F had important contributions from echinoderms and molluscs. Additionally, a general pattern of a decrease in the importance of annelids was observed between C sites and F sites. This was coupled with an increase in the contribution of molluscs and For inspection purposes only. echinoderms to the Consent community of copyright composition owner required for of any theseother use. offshore sites. For example, at sites A2-5, no echinoderms were found but at F sites they made up between 20-40% of the community.

Numerically, the most dominant animal throughout the survey area was the capitellid worm Capitella sp. This species was rare at most sites and its dominance can be attributed to the extremely high numbers present at site D4 (~2000 individuals per 0.1m 2). Capitellid worms are tolerant of stressful conditions and are indicators of a community that has been disturbed or impacted, particularly through organic enrichment.
No one species dominated all communities in the study area but the numerically commonly occuring fauna were those typical of sandy environments. Such species include the spionid polychaetes Magelona filiformis , Spio decorata and Spio martinensis , the bivalves Chamelea striatula and Fabulina fibula, amphipods of the genus Bathyporeia, echinoderms, in particular the urchin Echinocyamus pusillis, and the cirratulid polychaete Chaetozone christiei , as well as isolated incidences of Capitellid polychaetes in high abundance.
4.3.2 Multivariate analysis For inspection purposes only. Consent of copyright owner required for any other use.
4.3.2.1 Similarity analysis Benthic infauna data were clustered using Bray-Curtis similarity in order to identify any distinct communities present. The results of group average clustering analysis are shown in dendrograms on a per-replicate ( Figure 4.3) and per station ( Figure 4.4) basis.
Within site variability was found to be low at the majority of sites, replicates of each site had a 35% or more similarity with each other. The obvious exception to this was replicate B from reference site 1 where fauna was sparse and specific phyla, namely Annelida and Crustacea, were absent. As a result replicate B exhibited only a 5% similarity with the other replicates from this site. The reason for this anomaly is unknown, however it was noted that the sediment in this sample was anoxic and material was decayed (Hebog Environmental pers. comm ), this replicate was therefore deleted from subsequent analysis.
As well as good inter-site similarity, a high degree of similarity was also shown within each transect. For example, a similarity of 65% and more was observed between replicates at transect C.
The dendrograms ( Figure 4.3 and 4.4 ) showed that throughout the sampling area communities had a degree of homogeneity. Apart from site A6, the initial separation of sites did not occur until a 25% similarity level, as indicated in Figure 4.4 , which shows 4

distinct distinct clusters by similarity, as well as a further cluster formed from a single station (A6).
The formation of two major clusters within which sites were at least 40% similar to each other was then observed, sub-clusters of greater similarity were formed of the following: sites A2-5, B1-5 and sites C1-5, D1-6, E1-6, F1-6, reference sites 1 and 2.

For inspection purposes only. Consent of copyright owner required for any other use. The results of multi-dimensional scaling (MDS) using the similarity matrices derived from cluster analysis are plotted two dimensionally for each site in Figure 4.5. Stress values were low (0.07), indicating the two-dimensional MDS diagram was a very good representation of how the sites are related to each other.
It was observed that apart from A6, all the sites were positioned sequentially (A to F) along a parabolic line ( Figure 4.5 ). These sites were sampled along a transect with increasing depth from shore in a similar curve. However, this could not be the only factor explaining community variance as the line was not 1-dimensional (i.e. straight) and therefore indicated that two or more gradients were involved in determining community structure.
Together with the dendrograms, it was seen that there were five clusters; cluster 1 comprised site A6, cluster 2 sites A2-5, cluster 3 sites B1-5, cluster 4 sites C1-6, D1-6, E1-6 and reference sites 1 and 2 and cluster 5 sites F1-6. Each cluster was shown by superimposing a contour of 50% similarity level onto the diagram ( Figure 4.5 ).

Figure 4.5: MDS plot of sample sites (per replicate data) along the pipeline with superimposed contours showing the five clusters. A SIMPER 1 analysis was performed to determine which species contributed most to each cluster shown in Figure 4.4, and which species contributed most to the differences seen between clusters, allowing for communities to be identified ( Table 4.6). All clusters had average similarities of 55% or more. Throughout the sampling area, the important species were common to subtidal sand environments.

Clusters 2 and 3 (Sites A2-5 and B1-5) represented communities typical of inshore fine sandy sediments. Spionid polychaetes, such as Spio martinensis, Spio decorata, Spiophanes bombyx and Scolelepis , amphipods from the genus Bathyporeia and the white catworm Nephtys cirrosa were important contributors to community composition in these clusters.

Cluster 2 (A2-5) contained communities which had a mixture of species from these two environments, for example, Spio martinensis , an intertidal spionid and Spio decorata which prefers subtidal sand were both found in high numbers at these sites.
Spionid and cirratulid polychaetes and bivalves were the taxa which contributed highly to the community composition of sites in cluster 4 (Sites C1-6, D1-6, F1-6 and Reference sites 1 & 2). These included the species Magelona filiformis, Spiophanes bombyx, Spio decorata, Chaetozone christiei, Chamelea striatula, Abra (juvs) and Dosinia lupinus . Notably, most of the bivalves recorded were observed to be juveniles, there were however, adults of these species present indicating that they are a more permanent component of these communities.
Echinoids, bivalves such as Abra spp and Chamelea striatula , the cumacean Pseudocuma similis and the isopod Eurydice truncata were representative of communities in cluster 5 (sites F1-6). These animals are all typical of clean medium to fine subtidal sands with little or no mud content.
The dissimilarity between cluster 1 (site A6) and all other clusters was high. Fauna at this site was sparse and even though the species found here were from similar genera to those of the other sites, they were more typical of intertidal/infralittoral sand banks.

High dissimilarities also occurred between all other clusters, species which contributed highly to community composition at sites in one cluster were not as important to communities of the other sites. In particular, Spio martinensis at A sites, Spio decorata at A & B sites, Chamelea striatula, Chaetozone christiei and Fabulina fabula at C, D, E and reference sites and echinoids at F sites all contributed highly to the inter-community differences observed.
4.3.2.2 Correlation of physical and biological parameters
A BIO-ENV 2 test was performed for all stations. This looks at the best correlation between the biological and environmental data and endeavours to show which set of physical and chemical variables best explains the variation observed in the biological communities. Particle size, total organic carbon and depth were included in the analysis.
The BIO-ENV analysis showed that depth (m) explained most of the observed variance between sites (r = 0.828). However, although this correlation was very high, the best correlation was with two variables (r = 0.870), these being percentage of medium sand (250-499 µm) and depth (m). It is thought that depth may have had the most influential effect on community composition as grain size, which is known to have a significant effect on benthic communities, changes little along the whole pipeline. MDS overlays of these environmental variables were plotted for depth in Figure 4.6 , and for medium sand in Figure 4.7 .

Figure 4.7: MDS plot of sample sites along the pipeline with superimposed bubbles showing the percentage of medium sand (250-499µm) at each site.
The primary difference in community composition occurred between A6 and all other sites and this was where the major differences in these environmental variables lay. Site A6 had the highest proportion of medium sand at 67% and was in very shallow water (1m), all other sites sampled were in depths greater than 6m. However, patterns between the other clusters were also observed. Station depth increased between A and F sites. E and F sites were from the greatest depths (approximately 40m) whilst A sites were sampled from depths Forof inspectionless than purposes 10m. only.

4.3.3 Comparison of pre- and post-construction data Total number of species, total abundance and diversity are shown for each site surveyed in the 2008 pre construction survey and 2010 (12-month post-construction survey) ( Table 4.7 ). Benthic communities along the nearshore section of the pipeline showed little change between 2008 and 2010. Species numbers, abundance and diversity were approximately the same. A general increase in diversity was observed between A and F sites in both surveys, although this was more prominent in 2008. The proportion of each phyla at each site also exhibited the same general pattern, with echinoderms increasing in their importance and annelids contributing less the further offshore the site. However, in 2010, molluscs generally contributed more to the total abundance of animals at each site than in 2008. For example at sites F2-6, in 2008, molluscs contributed 15-25% of the total abundance at these sites whilst in 2010 this figure had risen to 20-50%. With this increase, annelids became less important, contributing only 10-15% in 2010 compared to 30-40% in 2008.

On the whole, communities surveyed in 2008 and 2010 comprised species typical of clean sandy environments with low mud and gravel content. Dominant species in both years were spionid and cirratulid polychaetes, Bathyporeia amphipods and tellinid and venerid bivalves. However, it was seen that the dominance of the spionid polychaete, Spiophanes bombyx observed in 2008 had reduced by 2010 and more abundant species were the spionid polychaete Spio decorata in A and B sites, Chaetozone

christiei and Magelona filiformis in C and D sites and the bivalves Chamelea striatula and Fabulina fabula at sites further offshore.
In 2010, site D4 had an extremely high abundance of the opportunistic polychaete Capitella . These polychaetes were absent from site D4 in 2008 and only found twice along the whole of the pipeline during that survey. As this species is a known indicator of a stressed environment, particularly from organic enrichment, it is likely that a disturbance event (such as the installation of the offshore pipeline) occurred between 2008 and 2010. The cause, and whether to be of anthropogenic or natural source, is unknown. The total organic content at this site was elevated in 2010 (0.23% compared to <0.01% in 2008), but these levels are still low and so it cannot be said for any certainty that this is the reason for the presence of Capitella .
The results of per replicate group average clustering analysis using Bray Curtis similarity are shown for each site surveyed in 2008 and 2010 (Figure 4.8 ). Communities varied little temporally, with similarities of 40% or more being observed between each site when surveyed in 2008 and 2010. Sites A2-5 had the highest level of similarity between the two years (at approximately 60%) and along with F sites showed the least temporal variation.

The results of multi-dimensional scaling using the similarity matrices derived from cluster analysis are plotted two dimensionally for each site with symbols denoting the survey year in Figure 4.9 . Stress values were moderate (0.12), indicating the two- dimensional MDS diagram was a reasonable representation of how sites are related to each other.
This plot showed that sites were spatially related to each other in an extremely consistent manner as they were placed sequentially along a parabolic line in both years. However, a shift in community composition had occurred between 2008 and 2010, with sites from the latter year being located towards the bottom of the plot. On the two dimensional MDS plot, communities at reference sites 1 and 2 appeared to show little change between years. However, when plotted three dimensionally, it was seen that these sites along with all others moved on another axis and sites surveyed in 2008 lay above sites surveyed in 2010. This indicated that there was more than one factor involved in the observed variance between communities.

Figure 4.9: MDS plot of sample sites along the pipeline in 2008 ( ) and 2010 ( ). A SIMPER analysis was performed to determine the cause of these community differences occurred. The results for this are shown in Table 4.8 . The two species which contributed most to the observed differences between years were the spionid polychaete Spiophanes bombyx and the bivalve Chamelea striatula . Although present in both surveys, S. bombyx was very important to community composition in over 90% of the sites surveyed in 2008 whereas by 2010 this importance had diminished and it did not contribute to the same degree at any of the sites. In 2010, Chamelea striatula had become the dominant species at many sites particularly E and F sites, but was of moderate abundance at these sites in 2008.

The reason for this change is unknown, and apart from site D4, communities in 2010 did not show indications of being biologically disturbed (i.e. low diversity, high numbers of opportunistic species). Additionally, there has been no significant change in grain size, organic carbon content or depth between the two years. It may be that this change occurred naturally or there has been a disturbance event and communities have recovered but exist now at a slightly different equilibrium. However, it is evident that these changes were not a result of works on the seabed during the laying of the pipeline as similar changes to community composition occurred in the reference sites located away from the pipeline route.

4.4 Interpretation of seabed photography
The photographic data obtained provide useful qualitative and supplementary information on sediments and larger biota in the survey area. For inspection purposes only. Consent of copyright owner required for any other use. The majority of the images show a seabed made up of sandy sediments. These results are as anticipated based on the particle size analysis data from the current survey, and also correspond with the results of the 2008 pre-construction and 2009 1-month post- construction surveys (RSK 2009 and RSK 2010 respectively). The majority of sites surveyed exhibit evidence of moderate to high energy wave/current exposure. At these sites sediments are well sorted and show wave/current derived ripple bedforms.
Table 4.9 summarises the key physical and biological features of interest at each transect, based on interpretation of the seabed photography.

Overall, the seabed photography recorded a similar physical and biological environment to that surveyed during the 2009 1-month post-construction survey. Minor differences can be observed at certain stations, however these variations are typically the result of the positioning of the camera on the seabed, rather than any perceived changes in the nature of the seabed. Seabed ripple bedforms are present at all transects from A-F, although they are less pronounced at those transects furthest to seaward and closest inshore. Greatest uniformity in bedform sand ripples occurs at transects B-D, where water depths are in the approximate range 10-40m below Chart Datum.
Fine-grained sands are the predominant seabed substrate, exceptions to this are observed at Station A1, B6, C6, and the original reference station #2. At Station A1 (Figure 4.10 ), where sediments were previously recorded as coarse-grained sands, in 2010 they showed a combination of bedrock and cobbles, with coarse sand. The photography, rather than showing a change in the nature of the seabed has highlighted the variable nature of the seabed within a relatively small area. This station is close to the cliffs and off lying rocks; as such also, within 10m of the target position the seabed is a mosaic of rock outcrops and macroalgal growth ( Figure 4.11 ). The remaining stations on transect A have a seabed comprised fine-grained sands, with evidence of high wave and current energy ( Figure 4.12 ).

Examples of sites on transects B, C and D can be seen in Figures 4.13, 4.14 and 4.15. These highlight the nature of the wave/current induced rippled, sandy seabed sediments. Transect D exhibits both rippled and less-pronounced seabed bedforms. Also noted at station B4 was evidence of the recent pipeline construction. Figure 4.27 shows the rock armour that was installed by fall-pipe vessel immediately prior to the 2009 survey. The photograph shown in Figure 4.27 was obtained at position 54.285ºN / 9.859ºW, approximately 20m from the target position at B4.
Fauna is very infrequently recorded at transects B-D, with the exception of stations B6 and C6, which have a bedrock and boulder bedform. The fine-grained sandy substrate sites with evidence of strong wave and tidal action, which typify the majority of the seabed throughout Broadhaven Bay, are characterised by low abundances and diversity of epibenthic species. The photography recorded very few sightings, although it is important to note that the field of view of the seabed camera is relatively small.

As expected, the seabed photography confirmed a higher-energy environment closer inshore.
Stations along transects E and F and to a degree D, exhibited less pronounced sand ripple bedforms, due to the reduced hydrodynamic energy at the seabed. Consequently, increased evidence of bioturbation in the form of small-scale burrows, mounds and faunal tracks were observed ( Figure 4.16, 4.17, 4.18 and 4.19 ). Station D6 ( Figure 4.16 ) shows evidence of reduced hydrodynamic energy impacting on the seabed environment.
Despite the increased evidence of bioturbation of the sediments (probably caused by polychaete worms, brittlestars, bivalves or amphipod shrimps), visible and identifiable biota were relatively infrequent over much of the sandy sediments throughout the bay, which is characteristic of this environment. Recorded fauna includes starfish (likely to be Luidia ciliaris ) and sand goby (likely to be Pomatoschistus minutes) ( Figure 4.18 and 4.19 ).

The fish in the bottom left of photo is likely to be a sand goby (Pomatoschistus minutus ). In comparison to the majority of sites, which were dominated by sand, some sites were characterised by hard substrate, which fell into two main types (shallow and deepwater).
In the shallower and well-lit waters at the northern ends of transects A, B and C, the bedrock and boulder substrates are dominated by an epibenthic community of encrusting red algae and red macroalgal species as shown in Figures 4.20 and 4.21 (Station B6) and Figures 4.22 For inspection and 4.23 purposes (Station only.

The second type of hard-substrate environment was observed at Reference Station #2, in water depths in excess of 50m ( Figure 4.25 ). At Reference Station #2 West, however (located for the sampling of seabed sediment) the seabed was characterised by a low energy fine-sand environment ( Figure 4.26 ).
Although the physical bedforms at Reference Station #2 appeared similar to those observed at shallower transects (i.e. bedrock and boulders), the increased water depth (and therefore reduced light availability) prevents significant algal growth. As such, species of flora are significantly reduced, and the epibenthic community is dominated by faunal species. In addition to increased depth, the reduction in hydrodynamic energy is another factor that has implications for the community that develops at these sites. The visible fauna is briefly summarised in Table 4.9 .
During the 2009 survey photographs taken at Reference Station #1 showed similar rock and boulder bedforms to those described above, however in 2010 (this survey) no hard rock substrate was observed. In 2009, the position photographed was slightly closer to the coast than in 2010, and as a consequence (due to the variable nature of the seabed substrates in this area) a sandy seabed, rather than hard rock was encountered.

Evidence of bioturbation in the form of tracks, burrows and the casts of infaunal polychaete worms.
Overall, very little evidence of pipeline construction could be observed from the seabed photography, however some evidence was observed while targeting Station B4 with the drop-down camera ( Figure 4.27 ). This photo was taken in almost the same location as the photo of the rock armour shown in the 2009 report (RSK, 2010) (within 5m) and provides a useful comparison, highlighting the degree of colonisation of the rock substrate by pioneering algal species.

5 Summary
5.1 Physico-chemical
The seabed throughout the sampling area was largely dominated by mobile soft sediments. These being almost entirely composed of sand. Within the sandy sediments, some variation was seen in the distribution of various fractions: Coarser sands were more in evidence at transect A (near to the shore) and transects E and F (seaward transects), while a lower proportion of coarse and a higher proportion of very fine sands was recorded at transects B, C, and D, in the central part of the pipeline sampling area. Fine sediment (mud), and consequently total organic carbon levels were low throughout the area, as expected for a high-energy Atlantic coastline without major riverine input.
A few areas were recorded as being hard substrate. These areas were anticipated due to the results of the seabed photography and confirmed by the subsequent difficulty or failure of the Day grab to collect samples at these locations. These included the area nearest to the Sruwaddacon estuary mouth (transect A), where two stations recorded rocky substrates. At either end of transect A hard rock was also encountered. At the northern extremes of transects B and C hard rock was encountered as well as at reference station #2. The rock armour filter layer protecting part of the pipeline was evident at the centre of transect B (This was incidentally observed from the seabed photography, and grab sampling was not undertaken here).
The results from the revisited survey locations (2008, 2009 and 2010 (this survey)) show no significant differences as a result of the installation of the pipeline. With the exception of direct photographic evidence for pipeline construction observed close to sampling stations B4 and potentially in the centre of transect A (discussed in Section 5.3), no appreciable impacts resulting from the pipeline could be determined in the results of the sediment sampling.
Comparison of the particle size data throughout the monitoring programme ( Table 4.2 ) shows no appreciable differences between surveys; sediments are largely classified the same (according to the Udden-Wentworth scale), and at the 5 stations where this classification varies between For inspectionsurveys purposes the differenconly. es in median particle size are minor and likely to be the resultConsent of of naturalcopyright owner temporal required forvar anyiation. other use.
Total Organic Content was recorded as low at all stations in 2008, 2009 and 2010. The results in Table 4.3 tend to indicate that overall TOC was slightly reduced in the 2009 and 2010 surveys compared to the pre-construction survey of 2008. No definitive conclusions can be suggested to explain these results.
5.2 Benthic infauna
In summary, the faunal communities observed in the current survey were of moderate to high diversity and generally exhibited high evenness and low dominance. These communities showed a high degree of homogeneity and species were typical of those found in sandy sediments, with high contributions to community composition from spionid and cirratulid polychaetes, the amphipod Bathyporeia and tellind and venerid bivalves.
Although communities at all sites showed a high level of similarity, the taxa which contributed most to community composition changed gradually between sites on A and F transects. Communities at A sites, particularly A6, were characterised by species
RSK Environment Ltd 53 RSK/He/P40036/40/03 rev01
EPA Export 12-11-2014:23:36:59 Corrib Broadhaven Bay Nearshore Pipeline Route – 12-Month Post Construction Survey 2010
typical of sandy sediments from the intertidal or infralittoral zone such as Bathyporeia pelagica and Spio martinensis , whereas species recorded at D, E and F sites were typical of offshore sands such as Chamelea striatula , Fabulina fabula and Echinocyamus pusillus . This feature was further illustrated by an MDS plot which showed the sequential positioning of sites A to F along a parabolic line.
A BIO-ENV analysis indicated which physical characteristics contributed to the variance observed between communities. It was found that depth explained a large proportion of this variance, and increased from A to F sites. However, this was not the only factor influencing community composition and the proportion of medium sand was also found to change between groups of sites, with A, E and F sites generally containing more of this fraction than other sites, and thus having an influence on community composition.
There was little change in the benthic communities between 2008 and 2010; the number of species, abundance and diversity were of a similar order for each site and species recorded were generally typical of clean sandy environments. There was however a shift in community composition at all sites, and the dominance of the spionid polychaete Spiophanes bombyx was observed to have decreased greatly in 2010. The reason for this change was unknown, but it cannot be ruled out that the observed changes were due to the disturbance event related to laying of the pipeline. Site D4 indicated possible signs of disturbance in 2010 due to the presence and high abundance of the opportunistic polychaete Capitella . As this species is a known indicator of a stressed environment, particularly from organic enrichment it is likely that this provides some evidence of a disturbance event having occurred between 2008 and 2010. The cause, and whether to be of anthropogenic or natural source, is unknown. The high abundance of Capitella at this station in 2010 corresponded with an elevated level of organic carbon, however it was still considered low. Due to the proximity of station D4 to the pipeline route, it cannot be ruled out that the construction of the pipeline during 2010 had an influence.
5.3 Seabed Photography
Video footage provided qualitative evidence of the subtidal environments in the area, and the still photographs, as in 2009, were of a very high quality (many of which have been included within this report). Sandy habitats ranged from shallow high-energy rippled sand to more settled For conditions inspection purposes with only. extensive evidence of bioturbation, and the Consent of copyright owner required for any other use. biota associated with these included infaunal polychaetes, and epifauna such as starfish, and demersal fish. Hard-substrate areas in shallow water supported a significant encrusting fauna, which included sponges, anemones, soft corals, hydroids, bryozoans and crinoids, as well as extensive algal growth.
Hard substrates in deeper waters where hydrodynamic activity was significantly reduced, lacked significant algal growth and were dominated by faunal species. An extensive faunal turf covered rock surfaces, and other notable species included sponges, solitary corals and anemones.
The interpretation of the seabed photography during this survey has not highlighted significant differences compared with the pre-construction survey of 2008 and the immediate post-construction survey of 2009. During those surveys photographic evidence supported the results of the sediment sampling, and showed an overall seabed of sand throughout Broadhaven Bay, with hard substrates close to the northern and eastern coasts (reference stations, and stations 6 on transect A, B, and C.
At certain stations (for example Reference Station #1) the seabed photography indicated differing seabed substrates between 2009 and 2010. These differences were not reflected in the sediment samples, and can be explained by slight differences in the positioning of the camera on the seabed and the mosaic nature of the seabed in these areas. Particularly in the case of reference station #1 (being close under the cliffs at

Rinnaglana) the sandy sediment is interspersed with areas of boulder and bedrock substrate, and as such marked changes can occur within a relatively small area.
Significant differences between 2008 and 2009 that showed evidence of pipeline construction were observed at one location, with potential evidence observed at a second: while targeting station B4 (evidence of the recently rock placed section of the nearshore pipeline ( Figure 4.27 )) and while targeting station A3, boulders, cobbles and coarser material were observed midway between stations A2 and A3. At the time of the 2009 survey, the potential that this showed evidence of washout from the causeway built to construct the pipeline landfall could not be ruled out. During this survey (2010) the rock berm was observed while targeting station B4 with the camera system. The photograph shown in Figure 4.27 was positioned within 5m of the corresponding photograph shown in the 2009 survey report (RSK, 2010) and shows the degree of colonisation of the hard rock substrate by pioneering algal and other epibenthic species. Otherwise, from the limited footage that was obtained at this location, the rock berm is not significantly altered from 2009.
The coarse sediments of boulders and cobbles observed along transect A in 2009 were not observed during 2010. During the 2010 survey the central stations along transect A exhibited a seabed of mobile rippled sand with no evidence of cobbles or coarser sand. These observations tend to support the findings of the sediment sampling, which recorded fine sand. It is possible that a similar trend to that observed during the 2010 landfall survey (RSK, 2011) is also being evidenced in the upper subtidal. The trend along the landfall transect in the intertidal zone showed that between 2009 and 2010 there was an increase in fine grained sand that had started to cover the coarser grain material left as a result of the landfall construction works. It is likely that this trend is continued into the shallow subtidal (Transect A).

Gyro Calibration Report
Overview
A TSS Meridian Surveyor Gyro compass was installed aboard the “Nomad” to provide vessel heading to enable accurate positioning of the vessels A Frame offset from the GPS antenna. A gyro calibration was carried out 11.06.10 to calculate the angular offset between the heading output by the gyro compass and the true heading of the vessel along its centre line. This gyro compass calibration was carried with the “Nomad” along-side the pier Ballyglass, Co. Mayo. The surveyor had been supplied with known heading of the pier.
Method
The heading (true) of Ballyglass pier 163.83° was supplied by Shell’s Paul Neale. The TSS Meridian Surveyor Gyro Compass was installed against a bulk head on the bridge of the Nomad, the latitude was manually set and it was allowed to settle for 10 hours. The Vessel was moored up securely alongside Ballyglass pier and the distance between the quay side and two points on the port side of the vessel were measured whilst the heading reported by the gyro compass was simultaneously logged. These measurements were repeated 10 times at an interval of 30 seconds. A spreadsheet was used to calculate (see 2 nd page of report) the mean offset between the known heading of the vessel and heading reported by the gyro compass.
Results
The result of calculations to determine the offset between the true heading of the vessel and the heading reported by the Gyro compass was a correction of -0.85° . This constant angular offset was applied in the online positioning software HydroPro.

Drop-down photography system
The camera system was based on the Benthic Solutions Ltd. (BSL) 3.4 megapixel digital camera system with video streaming operated through a surface controller and recording unit. The system had the capacity to be supplied with a unique freshwater lens system developed by BSL for operating in conditions with low ambient water clarity.
The key acquisition parameters of the system used were as follows:
Standard Features Comment Image Resolution 3.4 megapixel (2,048 x 1,536 pixels) Light Sensitivity setting ISO 100 Automatically Selected Sensor Type 1 / 1.8” format high density CCD sensor 2 x 250lumen controllable LED lamps Light source Stills strobe TTL controller Aperture priority at F7.4, Shutter speed typically Typical settings on this survey 1/60 th or 1/125 th second, Auto flash mode Framing Video Used 625 Line / 50 Hz PAL Control System BSL trigger and surface monitoring system Other Systems Freshwater Lens system (optional use)
The system was deployed from the stern of the vessel using a vertical drop-down frame technique and lowered to the seabed using the vessel’s winch. Height above the seabed was monitored using the online video to control the frames attitude once at the seabed. The seabed was surveyed using a combination of video (minimum 2 minutes) and digital stills photographs (minimum of 5 shots per site). Positioning of the system was based on an offset centred on a vertical deployment from the stern of the vessel.
All data were recorded to DV video and later transferred to DVD via firewire into a PC. Stills images have been reviewed and positions annotated to a separate survey file (Annex 3). The camera system was particularly useful in recording the heterogenic material found at the reference locations, along with stations A1, B6 and C6, some of which could not be sampled using standard grab sampler due to the nature of the For inspection purposes only. seabed.
