Measurements of Ice Shelf Water beneath the front of the Ross Ice Shelf using gliders [PDF]
Annals of Glaciology, 2017 Measurements made by an underwater glider deployed near the Ross Ice Shelf were used to identify the presence of Ice Shelf Water (ISW), which is defined as seawater with its potential temperature lower than its surface freezing point temperature ...

Ice-shelf retreat drives recent Pine Island Glacier speedup. [PDF]
Sci Adv, 2021 Antarctica’s largest contributor to sea level has sped up further as a major section of its floating ice shelf collapsed. Speedup of Pine Island Glacier over the past several decades has made it Antarctica’s largest contributor to sea-level rise.

Antarctic Seabed Assemblages in an Ice-Shelf-Adjacent Polynya, Western Weddell Sea [PDF]
Biology, 2022 Ice shelves cover ~1.6 million km2 of the Antarctic continental shelf and are sensitive indicators of climate change. With ice-shelf retreat, aphotic marine environments transform into new open-water spaces of photo-induced primary production and ...

Explicit representation and parametrised impacts of under ice shelf seas in the z∗ coordinate ocean model NEMO 3.6 [PDF]
Geoscientific Model Development, 2017 Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Two-timescale response of a large Antarctic ice shelf to climate change. [PDF]
Nat Commun, 2021 A potentially irreversible threshold in Antarctic ice shelf melting would be crossed if the ocean cavity beneath the large Filchner–Ronne Ice Shelf were to become flooded with warm water from the deep ocean.

Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West Antarctica. [PDF]
Sci Adv, 2021 The first oceanographic observations underneath Thwaites Ice Shelf front show previously unknown pathways for warm currents. Thwaites Glacier is the most rapidly changing outlet of the West Antarctic Ice Sheet and adds large uncertainty to 21st century ...

Physical processes controlling the rifting of Larsen C Ice Shelf, Antarctica, prior to the calving of iceberg A68. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance The stability of Antarctica and its contribution to sea-level rise are determined by the evolution of its ice shelves, which are vast expanses of floating ice that buttress the continent.

Observed interannual changes beneath Filchner-Ronne Ice Shelf linked to large-scale atmospheric circulation. [PDF]
Nat Commun, 2021 Floating ice shelves are the Achilles’ heel of the Antarctic Ice Sheet. They limit Antarctica’s contribution to global sea level rise, yet they can be rapidly melted from beneath by a warming ocean.

Damage accelerates ice shelf instability and mass loss in Amundsen Sea Embayment. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Pine Island Glacier and Thwaites Glacier in the Amundsen Sea Embayment are among the fastest changing outlet glaciers in Antarctica. Yet, projecting the future of these glaciers remains a major uncertainty for sea level rise.

Actively evolving subglacial conduits and eskers initiate ice shelf channels at an Antarctic grounding line [PDF]
Nature Communications, 2017 The formation mechanisms of ice-shelf channels remain poorly understood. Here, using ice-penetrating radar data, the authors propose that ice-shelf channel morphology in the Roi Baudouin Ice Shelf, East Antarctica, is seeded by esker ridges, indenting ...
