Southern Weddell Sea surface freshwater flux modulated by icescape and atmospheric forcing [PDF]

Ocean Science, 2023
Sea ice formation dominates surface salt forcing in the southern Weddell Sea. Brine rejected in the process of sea ice production results in the production of High Salinity Shelf Water (HSSW) that feeds the global overturning circulation and fuels the ...

Modeling ice‐ocean interaction in ice‐shelf crevasses [PDF]

Journal of Geophysical Research: Oceans, 2014
AbstractOcean freezing within ice‐shelf basal crevasses could potentially act as a stabilizing influence on ice shelves; however, ice‐ocean interaction and ocean dynamics within these crevasses are as yet poorly understood. To this end, an idealized 2‐D model of an ice‐shelf basal crevasse has been developed using Fluidity, a finite‐element ocean model

Ice-Ocean Interaction On Ronne Ice Shelf, Antarctica [PDF]

Annals of Glaciology, 1990
A detailed glaciological study of Ronne Ice Shelf has been undertaken along a flowline extending from Rutford Ice Stream grounding line to the ice front. Measurements of velocity, surface elevation, ice thickness, surface temperature and accumulation rate have been made at a total of 28 sites; at 17 of these ice deformation rates are also known ...

An ice-shelf model test based on the Ross Ice Shelf, Antarctica [PDF]

Annals of Glaciology, 1996
A standard numerical experiment featuring the Ross Ice Shelf, Antarctica, is presented as a test package for the development and intercomparison of ice-shelf models. The emphasis of this package is solution of stress-equilibrium equations for an ice-shelf velocity consistent with present observations.

The complex basal morphology and ice dynamics of the Nansen Ice Shelf, East Antarctica [PDF]

The Cryosphere
Ice shelf dynamics and morphology play an important role in the stability of floating bodies of ice by driving fracturing that can lead to calving, in turn impacting the ability of the ice shelf to buttress upstream grounded ice. Following a 2016 calving

Bathymetric and oceanic controls on Abbot Ice Shelf thickness and stability [PDF]

The Cryosphere, 2014
Ice shelves play key roles in stabilizing Antarctica's ice sheets, maintaining its high albedo and returning freshwater to the Southern Ocean. Improved data sets of ice shelf draft and underlying bathymetry are important for assessing ocean–ice ...

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

Warm ocean is eroding West Antarctic Ice Sheet [PDF]

, 2004
Satellite radar measurements show that ice shelves in Pine Island Bay have thinned by up to 5.5 m yr^{-1} over the past decade. The pattern of shelf thinning mirrors that of their grounded tributaries-the Pine Island, Thwaites and Smith glaciers- and ...

Ice Island Calvings and Ice Shelf Changes, Milne Ice Shelf and Ayles Ice Shelf, Ellesmere Island, N.W.T. [PDF]

ARCTIC, 1986
Analysis of vertical air photographs taken in 1959 and 1974 reveals that a total of 48 sq km, involving 3.3 cubic km, of ice calved from Milne and Ayles ice shelves between July 1959 and July 1974. In addition, Ayles Ice Shelf moved to about 5 km out of Ayles Fiord. It still occupied this exposed position in July 1984. The ice losses and movements have

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 (
