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 ...

Frazil dynamics and precipitation in a water column with depth-dependent supercooling [PDF]
, 2005 When seawater becomes supercooled, collections of small ice crystals, known as frazil ice, form and grow. A model of frazil ice dynamics is presented that deals explicitly with the buoyant settling of frazil crystals onto an overlying surface.

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.

Journal of Glaciology, 2022 Mass loss from ice shelves is a strong control on grounding-line dynamics. Here we investigate how calving and submarine melt parameterizations affect steady-state grounding-line positions and their stability.

Ice-shelf Response to Ice-stream Discharge Fluctuations: II. Ideal Rectangular Ice Shelf [PDF]
Journal of Glaciology, 1988 Abstract Abstract. Ice-shelf thickness and velocity anomalies resulting from ice-stream discharge fluctuations are calculated for an ideal ice shelf fed by a single ice stream and confined within a rectangular coastal geometry. Ice-shelf response to periodic forcing is found to be linear (thickness and velocity anomalies oscillate at ...

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

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.
