Ocean tide influences on the Antarctic and Greenland ice sheets
Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Closing the loops on Southern Ocean dynamics: From the circumpolar current to ice shelves and from bottom mixing to surface waves
A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial
role it plays in the global climate and the profound changes it is experiencing. The review …

A new tide model for the Antarctic ice shelves and seas
We describe a new tide model for the seas surrounding Antarctica, including the ocean
cavities under the floating ice shelves. The model uses data assimilation to improve its fit to …

Antarctic ice shelf potentially stabilized by export of meltwater in surface river
Meltwater stored in ponds and crevasses can weaken and fracture ice shelves, triggering
their rapid disintegration. This ice-shelf collapse results in an increased flux of ice from …

Net retreat of Antarctic glacier grounding lines
Grounding lines are a key indicator of ice-sheet instability, because changes in their position
reflect imbalance with the surrounding ocean and affect the flow of inland ice. Although the …

Distribution of marine ice beneath the Amery Ice Shelf
We present a map of the marine ice accreted to the base of the Amery Ice Shelf (AIS), East
Antarctica. This map is obtained by converting a Digital Elevation Model (DEM) of the AIS …

Automatic delineation of glacier grounding lines in differential interferometric synthetic-aperture radar data using deep learning
Delineating the grounding line of marine-terminating glaciers—where ice starts to become
afloat in ocean waters—is crucial for measuring and understanding ice sheet mass balance …

Surface meltwater drainage and ponding on Amery Ice Shelf, East Antarctica, 1973–2019
Surface melting on Amery Ice Shelf (AIS), East Antarctica, produces an extensive
supraglacial drainage system consisting of hundreds of lakes connected by surface …

Map** the grounding zone of the Amery ice shelf, East Antarctica using InSAR, MODIS and ICESat
We use a combination of satellite techniques (interferometric synthetic aperture radar
(InSAR), visible-band imagery, and repeat-track laser altimetry) to develop a benchmark …
