Abatement of Ocean-Wave Impact by Crevasses in an Ice Shelf

open access: yesJournal of Marine Science and Engineering, 2021
Forced ice-shelf oscillations modeling was undertaken employing a full 3D finite-difference model of an elastic ice shelf that was coupled to a treatment of under-shelf seawater flux.

Ice-shelf damming in the glacial Arctic Ocean: dynamical regimes of a basin-covering kilometre-thick ice shelf [PDF]

open access: yesThe Cryosphere, 2017
Recent geological and geophysical data suggest that a 1 km thick ice shelf extended over the glacial Arctic Ocean during Marine Isotope Stage 6, about 140 000 years ago.

Time-Dependent Modelling of the Wave-Induced Vibration of Ice Shelves

open access: yesJournal of Marine Science and Engineering, 2023
This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused on the effect of changes in the draft on the vibration of the ice shelf and presents both time-domain and frequency-domain ...

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

open access: yesOcean 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 ...

Summertime linkage between Antarctic sea-ice extent and ice-shelf basal melting through Antarctic coastal water masses’ variability: a circumpolar Southern Ocean model study

open access: yesEnvironmental Research Letters, 2021
Recent observations indicate that two cryospheric components, namely the Antarctic sea ice and ice shelf over the Southern Ocean, have been changing over the decades. Here we analyze results from an ocean–sea ice–ice shelf model to examine variability in

Impact of Subglacial Freshwater Discharge on Pine Island Ice Shelf

open access: yesGeophysical Research Letters, 2021
Satellite‐based estimates of ice shelf melt rates reach ∼ 200 m yr−1 close to the grounding line of Pine Island Glacier, in West Antarctica. However, ocean simulations have not yet been able to reproduce such high melt rates, even with high‐resolution ...

Atmospheric extremes caused high oceanward sea surface slope triggering the biggest calving event in more than 50 years at the Amery Ice Shelf

open access: yesThe Cryosphere, 2021
. Ice shelf instability is one of the main sources of uncertainty in Antarctica's contribution to future sea level rise. Calving events play a crucial role in ice shelf weakening but remain unpredictable, and their governing processes are still poorly ...

Ross ice shelf vibrations [PDF]

open access: yesGeophysical Research Letters, 2015
AbstractBroadband seismic stations were deployed across the Ross Ice Shelf (RIS) in November 2014 to study ocean gravity wave‐induced vibrations. Initial data from three stations 100 km from the RIS front and within 10 km of each other show both dispersed infragravity (IG) wave and ocean swell‐generated signals resulting from waves that originate in ...

A geomorphological overview of glacial landforms on the Icelandic continental shelf [PDF]

open access: yes, 2009
The availability of a bathymetric database that covers about 80% of the Icelandic shelf has made it possible to produce a geomorphological map of the glacial landforms.

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)

open access: yesJournal of Glaciology, 2020
Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due to climate forcing will decrease their ‘buttressing’ effect, causing a response in the grounded ice.
