Coastal Flood Defences - Groynes
Coastal Flood Defences - Groynes Coastal flood defences are key to protecting our coasts against flooding, which is when normally dry, low lying flat land is inundated by sea water. Hard engineering methods are forms of coastal flood defences which mitigate the risk of flooding and coastal erosion and the consequential effects. Hard Engineering Hard engineering methods are often used as a temporary measure to protect against coastal flooding as they are costly and only last for a relatively short amount of time before they require maintenance. However, they are very effective at protecting the coastline in the short-term as they are immediately effective as opposed to some longer term soft engineering methods. But they are often intrusive and can cause issues elsewhere at other areas along the coastline. Groynes are low lying wood or concrete structures which are situated out to sea from the shore. They are designed to trap sediment, dissipate wave energy and restrict the transfer of sediment away from the beach through long shore drift. Longshore drift is caused when prevailing winds blow waves across the shore at an angle which carries sediment along the beach.Groynes prevent this process and therefore, slow the process of erosion at the shore. They can also be permeable or impermeable, permeable groynes allow some sediment to pass through and some longshore drift to take place. However, impermeable groynes are solid and prevent the transfer of any sediment. Advantages and Disadvantages +Groynes are easy to construct. +They have long term durability and are low maintenance. +They reduce the need for the beach to be maintained through beach nourishment and the recycling of sand. -

What is an MPA? MPAs are a type of marine managed area (MMA) where marine or estuarine waters are set aside primarily to protect or conserve marine life and associated habitats. California has a coastal network of 124 protected areas designed to help increase the coherence and effectiveness of protecting the state’s marine life, habitats, and ecosystems. The network includes three types of MPA: state marine reserve (SMR), state marine conservation area (SMCA), and state marine park (SMP); one MMA: state marine recreational management area (SMRMA); and special closures. There are 119 MPAs, 5 MMAs and 15 special closures, each with unique boundaries and regulations in the network. Non-consumptive activities, restoration, and permitted scientific research are allowed. What is an SMCA? An SMCA is a type of MPA that protects resources by allowing for only specific types of recreational and/or commercial take to occur. (Area restrictions are defined in Title 14, Section 632(a)(1)(C)).

INTRODUCTION The rapid adoption of in situ studies to investigate lifeways of organisms in the oceans is succeeding in bringing the laboratory to the ocean. Before, the conclusions that observers and scientists were classically forced to accept oPcen represented in- accurate abstractions of things that could not be observed. During the past 10-20 years the cataloging of the fauna and flora of the coral reef habitats has been carried out at an escalated rate, coupled with the many and vast improvements in tools, allowing increased periods of continual observation under sea. -
Spatial and Temporal Distribution of the Demersal Fish Fauna in a Baltic Archipelago As Estimated by SCUBA Census
MARINE ECOLOGY - PROGRESS SERIES Vol. 23: 3143, 1985 Published April 25 Mar. Ecol. hog. Ser. 1 l Spatial and temporal distribution of the demersal fish fauna in a Baltic archipelago as estimated by SCUBA census B.-0. Jansson, G. Aneer & S. Nellbring Asko Laboratory, Institute of Marine Ecology, University of Stockholm, S-106 91 Stockholm, Sweden ABSTRACT: A quantitative investigation of the demersal fish fauna of a 160 km2 archipelago area in the northern Baltic proper was carried out by SCUBA census technique. Thirty-four stations covering seaweed areas, shallow soft bottoms with seagrass and pond weeds, and deeper, naked soft bottoms down to a depth of 21 m were visited at all seasons. The results are compared with those obtained by traditional gill-net fishing. The dominating species are the gobiids (particularly Pornatoschistus rninutus) which make up 75 % of the total fish fauna but only 8.4 % of the total biomass. Zoarces viviparus, Cottus gobio and Platichtys flesus are common elements, with P. flesus constituting more than half of the biomass. Low abundance of all species except Z. viviparus is found in March-April, gobies having a maximum in September-October and P. flesus in November. Spatially, P. rninutus shows the widest vertical range being about equally distributed between surface and 20 m depth. C. gobio aggregates in the upper 10 m. The Mytilus bottoms and the deeper soft bottoms are the most populated areas. The former is characterized by Gobius niger, Z. viviparus and Pholis gunnellus which use the shelter offered by the numerous boulders and stones. The latter is totally dominated by P. -

Race rocks (XwaYeN) proposed marine protected area ecosystem overview and assessment report. Can. Manuscr. Rep. Fish. Aquat. Sci. 2949: ii + 30 p. Executive Summary Background Race Rocks (XwaYeN), located 17 km southwest of Victoria in the Strait of Juan de Fuca, consists of nine islets, including the large main island, Great Race. Named for its strong tidal currents and rocky reefs, the waters surrounding Race Rocks (XwaYeN) are a showcase for Pacific marine life. This marine life is the result of oceanographic conditions supplying the Race Rocks (XwaYeN) area with a generous stream of nutrients and high levels of dissolved oxygen. These factors contribute to the creation of an ecosystem of high biodiversity and biological productivity. In 1980, the province of British Columbia, under the authority of the provincial Ecological Reserves Act, established the Race Rocks Ecological Reserve. This provided protection of the terrestrial natural and cultural heritage values (nine islets) and of the ocean seabed (to the 20 fathoms/36.6 meter contour line). -
Shrinking Shark Numbers on the Great Barrier Reef Unlikely to Have Cascading Impacts
Khaled bin Sultan Living Oceans Foundation 821 Chesapeake Avenue #3568 • Annapolis, MD 21403 443.221.6844 • LivingOceansFoundation.org FOR IMMEDIATE RELEASE Shrinking shark numbers on the Great Barrier Reef unlikely to have cascading impacts New evidence suggests that reef sharks exert weak control over coral reef food webs Shark populations are dwindling worldwide, and scientists are concerned that the decline could trigger a cascade of impacts that hurt coral reefs. But a new paper published in Ecology suggests that the effects of shark losses are unlikely to reverberate throughout the marine food web. Instead, the findings point to physical and ecological features, like the structure of coral reefs and patterns of water movement, as important regulators of coral reef communities. Lead author Amelia Desbiens, a marine ecologist at the University of Queensland in Brisbane, Australia, conducted the study using data collected by the Khaled bin Sultan Living Oceans Foundation during its 2014 Global Reef Expedition, which surveyed shark populations on the northern Great Barrier Reef. Back then, this area was one of the most pristine reef regions in the world. The divers were heartened by the dizzying array of fish species in some locations, counting a total of 433 species of coral reef fish across their study area. “We were pleasantly surprised at the status of the coral reefs and fish communities in the northern Great Barrier Reef when we surveyed them in 2014,” said Alex Dempsey, Director of Science Management at the Khaled bin Sultan Living Oceans Foundation, and one of the paper’s authors. “We saw a relatively high percentage of live coral cover, and an abundance of reef fish species that gave us hope that perhaps these reef systems were resilient and have been able to persistently flourish.” They also found that no-fishing zones had four times as many reef sharks as the zones that allow fishing. -

1 the Influence of Groyne Fields and Other Hard Defences on the Shoreline Configuration
1 The Influence of Groyne Fields and Other Hard Defences on the Shoreline Configuration 2 of Soft Cliff Coastlines 3 4 Sally Brown1*, Max Barton1, Robert J Nicholls1 5 6 1. Faculty of Engineering and the Environment, University of Southampton, 7 University Road, Highfield, Southampton, UK. S017 1BJ. 8 9 * Sally Brown ([email protected], Telephone: +44(0)2380 594796). 10 11 Abstract: Building defences, such as groynes, on eroding soft cliff coastlines alters the 12 sediment budget, changing the shoreline configuration adjacent to defences. On the 13 down-drift side, the coastline is set-back. This is often believed to be caused by increased 14 erosion via the ‘terminal groyne effect’, resulting in rapid land loss. This paper examines 15 whether the terminal groyne effect always occurs down-drift post defence construction 16 (i.e. whether or not the retreat rate increases down-drift) through case study analysis. 17 18 Nine cases were analysed at Holderness and Christchurch Bay, England. Seven out of 19 nine sites experienced an increase in down-drift retreat rates. For the two remaining sites, 20 retreat rates remained constant after construction, probably as a sediment deficit already 21 existed prior to construction or as sediment movement was restricted further down-drift. 22 For these two sites, a set-back still evolved, leading to the erroneous perception that a 23 terminal groyne effect had developed. Additionally, seven of the nine sites developed a 24 set back up-drift of the initial groyne, leading to the defended sections of coast acting as 1 25 a hard headland, inhabiting long-shore drift. -
Marine Protected Areas (Mpas) in Management 1 of Coral Reefs
ISRS BRIEFING PAPER 1 MARINE PROTECTED AREAS (MPAS) IN MANAGEMENT 1 OF CORAL REEFS SYNOPSIS Marine protected areas (MPAs) may stop all extractive uses, protect particular species or locally prohibit specific kinds of fishing. These areas may be established for reasons of conservation, tourism or fisheries management. This briefing paper discusses the potential uses of MPAs, factors that have affected their success and the conditions under which they are likely to be effective. ¾ MPAs are often established as a conservation tool, allowing protection of species sensitive to fishing and thus preserving intact ecosystems, their processes and biodiversity and ultimately their resilience to perturbations. ¾ Increases in charismatic species such as large groupers in MPAs combined with the perception that the reefs there are relatively pristine mean that MPAs can play a significant role in tourism. ¾ By reducing fishing mortality, effective MPAs have positive effects locally on abundances, biomass, sizes and reproductive outputs of many exploitable site- attached reef species. ¾ Because high biomass of focal species is sought but this is quickly depleted and is slow to recover, poaching is a problem in most reef MPAs. ¾ Target-species ‘spillover’ into fishing areas is likely occurring close to the MPA boundaries and benefits will often be related to MPA size. Evidence for MPAs acting as a source of larval export remains weak. ¾ The science of MPAs is at an early stage of its development and MPAs will rarely suffice alone to address the main objectives of fisheries management; concomitant control of effort and other measures are needed to reduce fishery impacts, sustain yields or help stocks to recover. -
DRAFT Sustainable Tourism for Marine Recreation Providers
DRAFT Sustainable Tourism for Marine Recreation Providers Wolcott Henry photo The Coral Reef Alliance: Coral Parks Program Education Series ©2004 Sustainable Tourism Introduction In this era of the global economy, tourism has become a primary source of revenue for many regions of the world, generating nearly $500 billion in worldwide revenues in 2001, and continuing to grow (WTO, 2001). The United Nations Environment Program (UNEP) facilitated a study that points out that the tourism industry now represents more than 10% of the world’s gross domestic product (UNEP, 2002). While tourism brings significant benefits for both local and global economies, its rapid growth and development in recent decades has caused widespread social and environmental change across the globe, particularly in popular coastal resort destinations. In contrast, the concept of sustainable tourism is now seen as a way to promote socio-economic development in a given region while simultaneously protecting local culture and the natural environment. In order to address these issues and how they impact coral reefs, the Coral Reef Alliance (CORAL) has compiled this Sustainable Tourism for Marine Recreation Providers handbook. In an effort to promote sustainable tourism, the information contained in this handbook highlights some of the current environmental problems associated with tourism growth and development, and promotes practical solutions for marine recreation providers to adopt good environmental practices. We encourage readers to provide us with feedback as to how we can improve this publication.
