TL;DR: In this article, data from instrumented elephant seals and moorings suggest an additional source of bottom-water formation in the Cape Darnley polynya that is driven by sea-ice production.

TL;DR: In this paper, the authors summarize the research to date on observing these trends, identifying their drivers, and assessing the role of anthropogenic climate change in Antarctic sea ice cover, concluding that the expected response is small compared to the very high natural variability of the system.

TL;DR: In this paper, the authors present a data set from the International Polar Year project; Marine Mammals Exploring the Oceans Pole to Pole for southern elephant seals, in which a large number of instruments (N = 287) deployed on animals, encompassing a broad circum-Antarctic geographic extent, collected in situ ocean data and at-sea foraging metrics that explicitly link foraging behavior and habitat structure in time and space.

TL;DR: In this paper, the authors present time series (April 1998 to May 1999 and August 1999 to February 2000) of data from temperature-salinity sensors, in both the Adelie Depression and the known outflow region of the adelie Sill, to describe the annual cycle of shelf water densities.

TL;DR: New observations from CTD-instrumented elephant seals in 2011–2013 are shown that provide the first complete assessment of dense shelf water formation in Prydz Bay, highlighting the susceptibility of Antarctic bottom water to increased freshwater input from the enhanced melting of ice shelves, and ultimately the potential collapse of AntarcticBottom water formationIn a warming climate.
