Basal melt of ice shelves is not only an important part of Antarctica's ice sheet mass budget,
but it is also the origin of platelet ice, one of the most distinctive types of sea ice. In many …

Systematic long-term studies on ecosystem dynamics are largely lacking from the East
Antarctic Southern Ocean, although it is well recognized that they are indispensable to …

The landscape of Antarctica, hidden beneath kilometre‐thick ice in most places, has been
shaped by the interactions between tectonic and erosional processes. The flow dynamics of …

Ice rises and rumples, locally grounded features adjacent to ice shelves, are relatively small
yet play significant roles in Antarctic ice dynamics. Their roles generally depend upon their …

The ice stream geometry and large ice surface velocities at the onset region of the Northeast
Greenland Ice Stream (NEGIS) are not yet well reproduced by ice sheet models. The …

Tides significantly affect polar coastlines by modulating ice shelf melt and modifying shelf
water properties through transport and mixing. However, the effect of tides on the marine …

Simulations of ice sheet evolution over glacial cycles require integration of observational
constraints using ensemble studies with fast ice sheet models. These include physical …

Knowledge of Antarctica's sedimentary basins builds our understanding of the coupled
evolution of 33 tectonics, ice, ocean, and climate. Sedimentary basins have properties …

Drill cores from the Antarctic continental shelf are essential for directly constraining changes
in past Antarctic Ice Sheet extent. Here, we provide a sedimentary facies analysis of drill …

The stability of ice shelves and drainage of ice sheets they buttress is largely determined by
melting at their atmospheric and oceanic interfaces. Subglacial bathymetry can impact ice …
