Ekström Ice Shelf, Antarctica [PDF]
Annals of Glaciology, 1988 In 1980–81, 1983–84 and 1985–86 airborne surveys with an electromagnetic reflection (EMR) system were made of Ekström Ice Shelf, Antarctica. The EMR data were supplemented by measurements of surface elevation with radar altimetry during flights at a constant pressure altitude.

Response to Filchner–Ronne Ice Shelf cavity warming in a coupled ocean–ice sheet model – Part 1: The ocean perspective [PDF]
Ocean Science, 2017 The Regional Antarctic ice and Global Ocean (RAnGO) model has been developed to study the interaction between the world ocean and the Antarctic ice sheet. The coupled model is based on a global implementation of the Finite Element Sea-ice Ocean Model (

Ice-shelf basal melting in a global finite-element sea-ice/ice-shelf/ocean model [PDF]
Annals of Glaciology, 2012 AbstractThe Finite Element Sea-ice Ocean Model (FESOM) has been augmented by an ice-shelf component with a three-equation system for diagnostic computation of boundary layer temperature and salinity. Ice-shelf geometry and global ocean bathymetry have been derived from the RTopo-1 dataset.

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.

Diagnosing the sensitivity of grounding-line flux to changes in sub-ice-shelf melting [PDF]
The Cryosphere, 2020 Using a numerical ice flow model, we study changes in ice shelf buttressing and grounding-line flux due to localized ice thickness perturbations, a proxy for localized changes in sub-ice-shelf melting. From our experiments, applied to idealized (MISMIP+)

Journal of Glaciology, 1950 Description of that part of the Larsen Shelf Ice traversed by the author when taking part in a sledging expedition which reached lat. 74° 42′ S., manned jointly by members of the Falkland Islands Dependencies Survey and the Ronne Antarctic Research Expedition 1946–48.

The air content of Larsen Ice Shelf [PDF]
Geophysical Research Letters, 2011 The air content of glacial firn determines the effect and attribution of observed changes in ice surface elevation, but is currently measurable only using labor-intensive ground-based techniques. Here a novel method is presented for using radar sounding measurements to decompose the total thickness of floating ice shelves into thicknesses of solid ice ...

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.

The Effects of Rotation and Ice Shelf Topography on Frazil-Laden Ice Shelf Water Plumes [PDF]
Journal of Physical Oceanography, 2006 Abstract A model of the dynamics and thermodynamics of a plume of meltwater at the base of an ice shelf is presented. Such ice shelf water plumes may become supercooled and deposit marine ice if they rise (because of the pressure decrease in the in situ freezing temperature), so the model incorporates both melting and freezing at the ice

History of the Larsen C Ice Shelf reconstructed from sub–ice shelf and offshore sediments [PDF]
Geology, 2021 Abstract Because ice shelves respond to climatic forcing over a range of time scales, from years to millennia, an understanding of their long-term history is critically needed for predicting their future evolution. We present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS), eastern Antarctic Peninsula (AP), based on ...
