Transport and variability of the Antarctic Circumpolar Current in Drake Passage
The baroclinic transport of the Antarctic Circumpolar Current (ACC) above 3000 m through Drake Passage is 107.3 ± 10.4 Sv and has been steady between 1975 and 2000. For six hydrographic sectionsExpand

South Georgia, antarctica: a productive, cold water, pelagic ecosystem
The South Georgia region is characterised by high biomass and productivity of phyto- plankton, zooplankton and vertebrate predators. Important commercial fisheries have been based at the island sinceExpand

Seasonal and interannual variability in temperature, chlorophyll and macronutrients in northern Marguerite Bay, Antarctica.
We report data from the first 8 years of oceanographic monitoring in Ryder Bay, northern Marguerite Bay, Antarctica. These data form the oceanographic component of the Rothera Oceanographic andExpand

Oceanic heat transport onto the Amundsen Sea shelf through a submarine glacial trough
Glaciers which drain the West Antarctic Ice Sheet (WAIS) into the Amundsen Sea are accelerating and thinning rapidly. These observations have been attributed to the regional oceanography wherebyExpand

Biomass of Antarctic krill in the Scotia Sea in January/February 2000 and its use in revising an estimate of precautionary yield
Abstract In January and February 2000, a collaborative survey designed to assess the biomass of Antarctic krill across the Scotia Sea was conducted aboard research vessels from Japan, Russia, the UKExpand

Interannual variability of the South Georgia marine ecosystem : biological and physical sources of variation in the abundance of krill
Interannual variability is a characteristic feature of the Southern Ocean ecosystem, yet the relative roles of biological and physical processes in generating these fluctuations are unknown. There isExpand

Revisiting Antarctic ice loss due to marine ice-cliff instability
Predictions for sea-level rise this century due to melt from Antarctica range from zero to more than one metre. The highest predictions are driven by the controversial marine ice-cliff instabilityExpand

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
This meeting explores the recent, rapid Arctic sea ice reduction. We will discuss the evidence for change, the inability of our climate models to predict these changes, the processes responsible forExpand

Antarctic Krill Under Sea Ice: Elevated Abundance in a Narrow Band Just South of Ice Edge
We surveyed Antarctic krill (Euphausia superba) under sea ice using the autonomous underwater vehicleAutosub-2. Krill were concentrated within a band under ice between 1 and 13 kilometers south ofExpand

Oceanographic variability and changes in Antarctic krill (Euphausia superba) abundance at South Georgia
Oceanographic data collected to the north of South Georgia were examined for three consecutive summers (1996/97, 1997/98, 1998/99). The results show the existence of a shelf break front during eachExpand
