Thirty years of elevation change on Antarctic Peninsula ice shelves from multimission satellite radar altimetry

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...

Satellite 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...

Transoceanic infragravity waves impacting Antarctic ice shelves

[1] Long-period oceanic infragravity (IG) waves (ca. [250, 50] s period) are generated along continental coastlines by nonlinear wave interactions of storm-forced shoreward propagating swell. Seismic observations on the Ross Ice Shelf show that free IG waves generated along the Pacific coast of North America propagate transoceanically to Antarctica, where they induce a much higher amplitude she...
