Antarctic Ice Sheet and Radar Altimetry: A Review
Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow monitoring of the shape and volume of ice sheets. Th...
متن کاملIce loss processes in the Seal Nunataks ice shelf region from satellite altimetry and imagery
The Seal Nunataks ice shelf (SNIS, ∼743 km in 2013) is an unofficial name for a remnant area between the former Larsen A and Larsen B ice shelves off the northeastern Antarctic Peninsula. Analyses using Landsat 7 ETM+ and Terra ASTER images from 2001 to 13 and ICESat altimetry from 2003 to 09 show it has retreated and thinned following the Larsen A (1995) and Larsen B (2002) disintegrations. De...
متن کاملSatellite Microwave Radar Observations of Antarctic Sea Ice
Since 1991, the European Space Agency’s two ERS satellites have acquired microwave radar data of Antarctica. ERS data have been recorded by two receiving stations, one German, one Japanese. The former has allowed direct downlink and recording of high bit-rate, high resolution SAR image data of the Weddell and Bellingshausen Seas during station campaigns. The latter has enabled some data from th...
متن کاملThe Topography and Surface Characteristics of the Larsen Ice Shelf, Antarctica, Using Satellite Altimetry
A comprehensive survey of the Larsen Ice Shelf has been conducted using precise orbit and re tracked Seasat radar-altimeter data with editing of erroneous values resulting from intrumental artefacts. Contour maps of elevation and radar back-scatter (with absolute accuracies of I m and 2 dB, respectively) have been produced and it has also been possible to map rifts, grounding points, rough terr...
متن کاملIce Measurements by Geosat Radar Altimetry
The surface topography of the Greenland and Antarctic ice sheets is the principal ice parameter obtainable from satellite radar altimetry. The improved ability of the GEOSA T altimeter to follow irregular surfaces and its extended operation have greatly increased the available topographic data on ice sheets for the study of ice dynamics and the possible detection of changes in global ice volume.
