Cross–Shelf Exchange Along the Antarctic Continental Margin: Modeling Results
The shelf areas around the Antarctic Continent are locations of dense water formation; part of these water masses ventilate the adjacent deep ocean basins and enter the global thermohaline circulation. This paper takes a look at regional differences of shelf sea–deep ocean exchange in high southern latitudes (mainly between the Weddell and Ross Seas), highlights a few physical mechanisms potent...
متن کاملSignificance of the Trace Fossil Zoophycos in Pliocene Deposits, Antarctic Continental Margin (ANDRILL 1B Drill Core)
Zoophycos is a complex three dimensional trace fossil that is abundant in deep ocean sediments worldwide, but has not been described previously from Cenozoic continental margin deposits of Antarctica. In the ANDRILL 1B core drilled through the northwest McMurdo ice shelf, Zoophycos occurs in a 17m thick unit of interglacial sediments bounded above and below by glacial surfaces of erosion. This ...
متن کاملDrilling Productivity on the Norwegian Continental Shelf
Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This cause cost cuts and project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates are obviously important. In new contracts for high-spec semi rigs on the Norwegian Conti...
متن کاملDecomposition of dissolved organic matter from the continental margin
Decomposition of dissolved organic carbon, nitrogen and phosphorus (DOC, DON, DOP) was measured for surface and bottom waters of the middle Atlantic bight (MAB) and deep slope water adjacent to the MAB on two occasions in March and August 1996. We used standard bottle incubation techniques to measure the decrease in dissolved organic matter (DOM) concentrations over a 180-day interval. Generall...
متن کاملProbabilistic sequence alignment of stratigraphic records
The assessment of age uncertainty in stratigraphically aligned records is a pressing need in paleoceanographic research. The alignment of ocean sediment cores is used to develop mutually consistent age models for climate proxies and is often based on the δO of calcite from benthic foraminifera, which records a global ice volume and deep water temperature signal. To date, δO alignment has been p...
