Holocene variations of sea-surface conditions in the southeastern Barents Sea, reconstructed from dinoflagellate cyst assemblages
Palynomorphs were analysed in two sediment cores from the southeastern Barents Sea representing the past 8.3 and 4.4 kyr. High dinocyst contents and species diversity enabled the application of the best analogue method to quantitatively reconstruct sea-surface salinities, temperatures and ice cover using 677 modern reference sites from the North Atlantic and Arctic seas, including new data from...
متن کاملLatest Quaternary palaeoceanographic change in the eastern North Atlantic based upon a dinoflagellate cyst event ecostratigraphy
The analyses of dinoflagellate cyst records, from the latest Quaternary sediments recovered from DSDP Core 610A taken on the Feni Ridge in the southern Rockall Trough, and part of core MD01-2461 on the continental margin of the Porcupine Seabight in the eastern North Atlantic Ocean, has provided evidence for significant oceanographic change encompassing the Last Glacial Maximum (LGM) and part o...
متن کاملseismo-geotechnical zonation mapping of southern caspian sea coastline
natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in iran. spotting such a high risk areas can help reducing the amount of their probable risk. a 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the caspian sea. this geotechnical hazard map divides the study area to 15 hazard classes (...
متن کاملCopepod feeding behaviour and egg production during a dinoflagellate bloom in the North Sea
Feeding strategies of copepods were studied during a dinoflagellate-dominated bloom in the North Sea in August 2001. The aim of this study was to evaluate the importance of mesozooplankton grazing as a biological loss factor of harmful algal blooms under natural conditions. Therefore, ingestion, egestion and egg production experiments were performed with the most abundant copepod species Calanu...
متن کاملThe End of a Myth: Arpylorus Antiquus Paleozoic Dinoflagellate Cyst
Arpylorus antiquus, erected by Calandra (1964), was isolated from Upper Silurian sedimentary rocks from the Mechiguig-1 borehole in southern Tunisia, with other palynomorphs. The folded vesicle and the quadrangular form of the aperture breaks down into plate-like fragments, resembling the tabulation of dinoflagellates. The presence of these elements, have been used to interpret A. antiquus as a...
