Abstract The East Antarctic Ice Sheet contains the vast majority of Earth's glacier ice (about
52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming …

Abstract The Antarctic Slope Current (ASC) is a coherent circulation feature that rings the
Antarctic continental shelf and regulates the flow of water toward the Antarctic coastline. The …

The Antarctic ice sheet has been losing mass over past decades through the accelerated
flow of its glaciers, conditioned by ocean temperature and bed topography. Glaciers …

Abstract The Antarctic Ice Sheet is an important indicator of climate change and driver of sea-
level rise. Here we combine satellite observations of its changing volume, flow and …

Ice discharge from large ice sheets plays a direct role in determining rates of sea-level rise.
We map present-day Antarctic-wide surface velocities using Landsat 7 and 8 imagery …

The circulation of the Southern Ocean connects ocean basins, links the deep and shallow
layers of the ocean, and has a strong influence on global ocean circulation, climate …

Abstract Fluctuations in Antarctic Ice Sheet elevation and mass occur over a variety of time
scales, owing to changes in snowfall and ice flow. Here we disentangle these signals by …

Abstract The Totten Glacier in East Antarctica, with an ice volume equivalent to> 3.5 m of
global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean …

Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool
and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the …

This chapter assesses the state of physical, biological and social knowledge concerning the
Arctic and Antarctic ocean and cryosphere, how they are affected by climate change, and …
