The variability of the Antarctic and Greenland ice sheets occurs on various timescales and is
important for projections of sea level rise; however, there are substantial uncertainties …

Marine ice sheets are highly sensitive to submarine melting in their grounding zones, where
they transition between grounded and floating ice. Recently published studies of the …

Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level
rise; however, ice shelf health remains poorly constrained. Here, we present the annual …

Abstract Pine Island Glacier (PIG), a part of the West Antarctic marine ice sheet, has recently
undergone substantial changes including speed up, retreat and thinning. Theoretical …

The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change.
The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic …

Accelerating ice loss from Thwaites Glacier is contributing approximately 5% of global sea‐
level rise, and could add tens of centimeters to sea level over the coming centuries. We use …

Ice streams such as Pine Island and Thwaites Glaciers which terminate at their ice shelves
in the eastern Amundsen Sea, West Antarctica, are losing mass faster than most others …

Elevated ice shelf melt rates in West Antarctica have been attributed to transport of warm
Circumpolar Deep Water (CDW) onto the continental shelf via bathymetric troughs. These …

Ocean warming around Antarctica has the potential to trigger marine ice‐sheet instabilities.
It has been suggested that abrupt and irreversible cold‐to‐warm ocean tipping points may …

The Amundsen Sea sector has some of the fastest-thinning ice shelves in Antarctica, caused
by high, ocean-driven basal melt rates, which can lead to increased ice stream flow, causing …
