Oceanographic conditions beneath Fimbul Ice Shelf, Antarctica [PDF]

, 2012
Antarctic ice shelves play a key role in the global climate system, acting as important sites for the cooling of shelf waters, thereby facilitating deep and bottom water formation.

Past ice sheet–seabed interactions in the northeastern Weddell Sea embayment, Antarctica [PDF]

The Cryosphere, 2020
The Antarctic ice sheet extent in the Weddell Sea embayment (WSE) during the Last Glacial Maximum (LGM; ca. 19–25 calibrated kiloyears before present, ka cal BP) and its subsequent retreat from the shelf are poorly constrained, with two ...

Ice‐Front Retreat Controls on Ocean Dynamics Under Larsen C Ice Shelf, Antarctica

Geophysical Research Letters, 2023
Iceberg A‐68 separated from the Larsen C Ice Shelf in July 2017 and the impact of this event on the local ocean circulation has yet to be assessed.

Investigating the impact of sub-ice shelf melt on Antarctic ice sheet spin-up and projections [PDF]

The Cryosphere
Sub-ice shelf melting is critical for the stability of the Antarctic ice sheet, as it influences ice-shelf buttressing that reduces grounded ice flow. Previous studies have emphasized that uncertainties in the state of sub-ice shelf melting contribute to

Residence Time and Transformation of Warm Circumpolar Deep Water on the Antarctic Continental Shelf

Geophysical Research Letters, 2021
Inflow of warm modified Circumpolar Deep Water (CDW) onto the Antarctic continental shelf and into ice shelf cavities is a key driver of Antarctic ice shelf mass loss.

Getz Ice Shelf melt enhanced by freshwater discharge from beneath the West Antarctic Ice Sheet [PDF]

The Cryosphere, 2020
Antarctica's Getz Ice Shelf has been rapidly thinning in recent years, producing more meltwater than any other ice shelf in the world. The influx of fresh water is known to substantially influence ocean circulation and biological productivity, but ...

The DOE E3SM v1.2 Cryosphere Configuration: Description and Simulated Antarctic Ice‐Shelf Basal Melting

Journal of Advances in Modeling Earth Systems, 2022
The processes responsible for freshwater flux from the Antarctic Ice Sheet (AIS), ice‐shelf basal melting and iceberg calving, are generally poorly represented in current Earth System Models (ESMs).

Radar profiles across ice-shelf channels at the Roi Baudouin Ice Shelf, Antarctica

, 2023
Ice shelves around Antarctica can restrict outlet glaciers and control ice-sheet mass loss. They often contain narrow, curvilinear tracts of thin ice termed ice-shelf channels.

Ice Velocity Variations of the Cook Ice Shelf, East Antarctica, from 2017 to 2022 from Sentinel-1 SAR Time-Series Offset Tracking

Remote Sensing, 2023
The Cook Glacier drains a significant portion of the Wilkes Subglacial Basin, the largest subglacial basin in East Antarctica—which feeds the Cook Ice Shelf.

Ephemeral grounding on the Pine Island Ice Shelf, West Antarctica, from 2014–2023 [PDF]

The Cryosphere
Ephemeral grounding refers to the intermittent contact between an ice shelf and elevated seafloor features. The evolution of ephemeral grounding of an ice shelf can affect buttressing, alter ice flow dynamics, and influence ice shelf stability. Long-term
