Eddy and tidal driven basal melting of the Totten and Moscow University ice shelves

open access: yesFrontiers in Marine Science, 2023
The mass loss from the neighboring Totten and Moscow University ice shelves is accelerating and may raise global sea levels in coming centuries. Totten Glacier is mostly based on bedrock below sea level, and so is vulnerable to warm water intrusion ...

A comparison of contemporaneous airborne altimetry and ice-thickness measurements of Antarctic ice shelves

open access: yesJournal of Glaciology, 2023
Estimates of ice shelf mass loss are typically based on surface height measurements, assuming hydrostatic equilibrium and estimated firn thickness.

Brief communication: widespread potential for seawater infiltration on Antarctic ice shelves [PDF]

open access: yesThe Cryosphere, 2018
Antarctica's future contribution to sea level change depends on the fate of its fringing ice shelves. One factor which may affect the rate of iceberg calving from ice shelves is the presence of liquid water, including the percolation of seawater into ...

On the Multiscale Oceanic Heat Transports Toward the Bases of the Antarctic Ice Shelves

open access: yesOcean-Land-Atmosphere Research, 2023
The mass balance of the Antarctic Ice Sheet (AIS) is important to global sea-level change. The AIS loses mass mainly through basal melting and subsequent calving of the Antarctic ice shelves.

A phase field model for fractures in ice shelves

open access: yesPamm, 2023
Ice shelves are large floating ice masses, that are formed when glaciers are becoming afloat at the margin of ice sheets. One dominating mass loss mechanism of ice shelves is calving, describing the detachment of icebergs at the front.

Brief communication: A submarine wall protecting the Amundsen Sea intensifies melting of neighboring ice shelves [PDF]

open access: yesThe Cryosphere, 2019
Disintegration of ice shelves in the Amundsen Sea, in front of the West Antarctic Ice Sheet, has the potential to cause sea level rise by inducing an acceleration of ice discharge from upstream grounded ice. Moore et al.

The circum-Antarctic ice-shelves respond to a more positive Southern Annular Mode with regionally varied melting

open access: yesCommunications Earth & Environment, 2022
The Southern Hemisphere cryosphere has recently shown regionally-contrasted responses to climate change, in particular to the positive phases of the Southern Annular Mode.

Characteristics of surface “melt potential” over Antarctic ice shelves based on regional atmospheric model simulations of summer air temperature extremes from 1979/80 to 2018/19

open access: yesJournal of Climate, 2022
We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq, %) and intensity (MPI-int, K) of daily maximum summer temperatures exceeding a melt threshold of 273.15 K.

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

open access: yes, 2014
We present radio-echo sounding data and satellite imagery, revealing a series of ancient large sub-parallel subglacial channels preserved in the region between the Möller and Foundation Ice Streams, West Antarctica.
