Antarctic ice-shelf thickness from satellite radar altimetry

J.A. Griggs, J.L. Bamber
2011 Journal of Glaciology  
Ice-shelf thickness is an important boundary condition for ice-sheet and sub-ice-shelf cavity modelling.  ...  Surface elevations derived from these instruments are interpolated on to regular grids using kriging, and converted to ice thicknesses using a modelled firn-density correction.  ...  and in situ measurements across West Antarctica (Griggs and Bamber, 2009a) .  ...

2021 The Cryosphere  
Retreat concentrated along the Antarctic Peninsula and West Antarctica including the biggest ice shelves (Ross and Ronne).  ...  For the first time, we present a circum-Antarctic record of glacier and ice shelf front change over the last two decades in combination with environmental variables such as air temperature, sea ice days  ...  We thank the Copernicus Climate Data Store for providing the ERA5 climate data and the Ocean and Sea Ice Satellite Application Facility (OSI SAF) for providing the sea ice concentration data sets.  ...

Increased West Antarctic ice discharge and East Antarctic stability over the last seven years

Alex S. Gardner, Geir Moholdt, Ted Scambos, Mark Fahnstock, Stefan Ligtenberg, Michiel van den Broeke, Johan Nilsson
2017 The Cryosphere Discussions  
Flow accelerations across the grounding lines of West Antarctica's Amundsen Sea Embayment, Getz Ice Shelf and Marguerite Bay on the western Antarctic Peninsula, account for 89 % of this increase  ...  The modest increase in ice discharge over the past 7 years is contrasted by high rates of ice sheet mass loss and distinct spatial patters of elevation lowering.  ...  Overall, changes in surface velocity along groundling lines of ice streams and glaciers feeding the major ice shelves of East and West Antarctica have not been large enough to significantly impact the  ...

Measurements and modelling of tidal ice-shelf flexure in Antarctic grounding zones [article]

Christian T. Wild, University Of Canterbury
2019
However, the behaviour of ice when subjected to a tidal forcing is uncertain, and complicated even further by inherently inaccurate predictions of tide models around Antarctica.  ...  Laboratory measurements of glacial ice properties deviate largely from field observations both in space and time, and modern tide models are still most inaccurate in coastal areas.  ...  Filchner Ice Shelf System' (NE/L013770/1).  ...
