Benthos Supported by the Tunnel-Valleys of the Southern North Sea
Benthos supported by the tunnel-valleys of the southern North Sea Bryony Pearce1*, David, R.Tappin2, Dayton Dove3 & Jennifer Pinnion1 1. Marine Ecological Surveys Limited, 3 Palace Yard Mews, Bath BA1 2NH 2. British Geological Survey, Keyworth, Nottingham 3. British Geological Survey, Edinburgh * Corresponding Author; Email: [email protected], Telephone: +44(0) 1225 442211, Fax: +44 (0) 1225 444411 Abstract The tunnel-valleys of the southern North Sea are arcuate sub-linear seabed depressions. The origin of these features has been the subject of much discussion, but they are generally considered to have been formed by subglacial erosion and sediment backfill beneath the outer margins of a receding ice sheet. We present here a study of two southern North Sea tunnel-valleys, the Silver and Sole Pits. Extensive areas of Sabellaria spinulosa reefs have been identified on the western flanks of the Silver Pit which extend down to the valley floor. It is likely that this reef complex would qualify as an Annex I habitat. The seabed of the Sole Pit is characterised by much sandier deposits than that of the Silver Pit, and supports an abundant bivalve community, dominated by Abra alba. This bivalve assemblage also contained Coarcuta obliquata which has only been recorded once before in the UK. Key Words Tunnel Valley, Benthos, Habitat, Seabed Mapping, Sabellaria spinulosa, Annex I Habitat, North Sea, Mulitbeam Introduction Tunnel-valleys are prominent features of the southern North Sea, where they form arcuate sub-linear seabed depressions with a limited sediment infill (Fig. 1). In the outer Humber area the valleys attain water depths up to 100 m and radiate outward from the mapped palaeo-ice margin of the Devensian (Weischelian) glaciations. -
Response to Oxygen Deficiency (Depletion): Bivalve Assemblages As an Indicator of Ecosystem Instability in the Northern Adriatic Sea

This paper shows that Bivalve assemblages could serve as excellent indicators of disturbance and ecosystem instability. The goal of this study was to compare two sets of data in order to determine the differences between two different periods belonging to Bivalve assemblage in the muddy detritic bottom of the northern Adriatic Sea in the post-anoxic period during December 1989, 1990, 1991 and quite a while later, during 2003, 2004 and 2005. Abundances of some indicator species such as Corbula gibba, Modiolarca subpicta, and Timoclea ovata were detected during the post-anoxic period. Recruitment in the quality of Bivalve assemblages was proved by the ecologic and biotic indexes during 2003, 2004 and 2005, during a period of relatively stable ecological conditions. Fluctuation in Bivalve diversity due to the ecological quality of the marine ecosystem in the eastern part of the northern Adriatic Sea is also discussed. Key words: hypoxia; Bivalve assemblages; indicator species; soft bottoms; northern Adriatic Sea Introduction Recent reviews and summaries have provided good introductions on how hypoxia and anoxia came to be such a large and serious problem in the aquatic ecosystem (Gray et al. -

The discoveries of oil in the Devonian reef at Norman Wells and in Cambrian sands at Tedji Lake have attested to the area's hydrocarbon potential. Surface mapping and local studies have revealed rock sequences and crustal structures of great potential value to our understanding of global geology. The aim of this report is to assist evaluation of the economic potential and to improve the interpretation of the geological history. -

Hummocky Karren Lukas Plan1, Christa Renetzeder2, Rudolf Pavuza3, and Wilfred Körner4
International Journal of Speleology 41 (1) 75-81 Tampa, FL (USA) January 2012 Available online at scholarcommons.usf.edu/ijs/ & www.ijs.speleo.it International Journal of Speleology Official Journal of Union Internationale de Spéléologie A new karren feature: hummocky karren Lukas Plan1, Christa Renetzeder2, Rudolf Pavuza3, and Wilfred Körner4 Abstract: Plan L., Renetzeder C., Pavuza R. and Körner W. 2012. A new karren feature: hummocky karren. International Journal of Speleology, 41(1), 75-81. Tampa, FL (USA). ISSN 0392-6672. http://dx.doi.org/10.5083/1827-806X.41.1.8. Karren are small-scale landforms on karst surfaces and many types have been described so far. Here we present an apparently new feature which was found on the Hochschwab karst massive in the Northern Calcareous Alps of Austria. So far only few outcrops each having less than 1 m² within a very restricted area have been found. Morphometric analysis reveals that the karren consist of a randomly distributed, dispersed assemblage of small hummocks and depressions in between. The mean distance between neighbouring hummocks is 4 to 5 cm and the mean height is 0.85 cm. Longitudinal sections are gently sinuous. The occurrences are delimited by thin soil cover with grassy vegetation and the karren continue below that vegetation cover. Therefore, it is clear that the features have formed subcutaneously. Corroded fissures where water could infiltrate into the epikarst are absent. The bedrock lithology is Middle Triassic limestone of the Wetterstein Formation in lagoonal facies. Geological structures do not govern the feature. The surface is not a bedding plane and small joints and fractures do not govern the arrangement of the hummocks. -

Corals (Anthozoa, Tabulata and Rugosa) and chaetetids (Porifera) from the Devonian of the Semara area (Morocco) at the Museo Geominero (Madrid, Spain), and their biogeographic significance Andreas MAY Saint Louis University - Madrid campus, Avenida del Valle 34, E-28003 Madrid, Spain e-mail: [email protected] Abstract. The paper describes the three tabulate coral species Caliapora robusta (Pradáčová, 1938), Pachyfavosites tumulosus Janet, 1965 and Thamnopora major (Radugin, 1938), the rugose coral Phillipsastrea ex gr. irregularis (Webster & Fenton in Fenton & Fenton, 1924) and the chaetetid Rhaphidopora crinalis (Schlüter, 1880). The specimens are described for the first time from Givetian and probably Frasnian strata of Semara area (Morocco, former Spanish Sahara). The material is stored in the Museo Geominero in Madrid. The tabulate corals and the chaetetid demonstrate close biogeographic relationships to Central and Eastern Europe as well as to Western Siberia. The fauna does not show any special influence of the Eastern Americas Realm.

A New Evaluation of Fluid Inclusion Data Based on Thermal Basin Modeling for the Drau Range, Eastern Alps

Acknowledgement 84 References 84 Abstract Published microthermometrical data of fluid inclusions, which were trapped near or subsequent to the time of maximum subsidence of the Drau Range (Eastern Alps) have been used to evaluate the relationship between fluid flow and heat transfer. The evaluation is based on a numerical 1-D heat flow model, calibrated with vitrinite reflectance values. Aqueous fluid inclusions in quartz fissures crosscutting Permo-Scythian sediments and in fluorites hosted by Carnian carbonates give evidence for conductive heat transfer during fluid flow in the Late Cretaceous/Neogene. This implies that trapping temperatures of these fluids (125 °C to 220 °C in quartz, 115 °C to 180 °C in fluorite) can be used to approximate the burial temperatures (190 °C in the Permo-Scythian, 130 °C to 150 °C in the Carnian). -

Age and Evolution of the Wetterstein Carbonate Platform in SW Serbia (Zlatibor Mountain)

These slides occur tectonically on top of the Drina-Ivanjica Palaeozoic and the late Middle to early Late Jurassic ophiolitic mélange respectively the ophiolites and not below as interpreted before. These slides were interpreted to derive from the Drina-Ivanjica Unit, where they should have formed the original sedimentary cover, disintegrated in the Late Jurassic. According to our investigations the slides of this carbonate-clastic mélange differ in age, facies and palaeogeographic origin. The carbonate rocks are originated from a relatively broad shelf in the Triassic facing the Neotethys Ocean to the east, maybe also from the adjacent Drina-Ivanjica Unit and from further east.
