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 کاملAtlantic water variability on the SE Greenland continental shelf and its relationship to SST and bathymetry
[1] Interaction of warm, Atlantic-origin water (AW) and colder, polar origin water (PW) advecting southward in the East Greenland Current (EGC) influences the heat content of water entering Greenland’s outlet glacial fjords. Here we use depth and temperature data derived from deep-diving seals to map out water mass variability across the continental shelf and to augment existing bathymetric pro...
متن کاملDistribution of Upper Circumpolar Deep Water on the warming continental shelf of the West Antarctic Peninsula
We use autonomous underwater vehicles to characterize the spatial distribution of Upper Circumpolar Deep Water (UCDW) on the continental shelf of the West Antarctic Peninsula (WAP) and present the first near-synoptic measurements of mesoscale features (eddies) containing UCDW on the WAP. Thirty-three subsurface eddies with widths on the order of 10 km were detected during four glider deployment...
متن کاملFishes on the Antarctic continental shelf: evolution of a marine species flock?
Distance, currents, deep water and sub-zero temperatures isolate the waters of the Antarctic continental shelf from other shelf areas in the Southern Hemisphere. The Antarctic shelf is an insular evolutionary site for a variety of marine organisms. The fish fauna is relatively small and unusual in composition, consisting of 213 species with higher taxonomic diversity restricted to 18 families. ...
متن کاملHigh particle export over the continental shelf of the west Antarctic Peninsula
[1] Drifting cylindrical traps and the flux proxy Th indicate more than an order of magnitude higher sinking fluxes of particulate carbon and 234Th in January 2009 than measured by a time‐series conical trap used regularly on the shelf of the west Antarctic Peninsula (WAP). The higher fluxes measured in this study have several implications for our understanding of the WAP ecosystem. Larger sink...
