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.

Formation of sea ice ponds from ice-shelf runoff, adjacent to the McMurdo Ice Shelf, Antarctica
Annals of Glaciology, 2020 Ponds that form on sea ice can cause it to thin or break-up, which can promote calving from an adjacent ice shelf. Studies of sea ice ponds have predominantly focused on Arctic ponds formed by in situ melting/ponding.

Modelling the influence of marine ice on the dynamics of an idealised ice shelf
Journal of Glaciology, 2023 Understanding the dynamic behaviour of ice shelves, specifically the controls on their ability to buttress the flow of ice into the ocean, is critical for predicting future ice-sheet contributions to sea level rise.

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 ...

Seasonal inflow of warm water onto the southern Weddell Sea continental shelf, Antarctica [PDF]
, 2012 To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region, 19 Weddell seals were tagged with miniaturized conductivity–temperature–depth sensors in February 2011.

The ice dynamic and melting response of Pine Island Ice Shelf to calving [PDF]
, 2022 Sea level rise contributions from the Pine Island Glacier (PIG) are strongly modulated by the backstress that its floating extension – Pine Island Ice Shelf (PIIS) – exerts on the adjoining grounded ice.

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.

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