Characteristic Geometry of Keels in Arctic Sea Ice Ridges
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Deformation within and between sea ice floes creates pressure ridges, which compose a considerable volume fraction of the Arctic sea ice cover and complicate sea ice volume measurements. An important parameter for quantifying the ice volume contained in these deformation features is the keel shape.

Satellite Altimetry for Earth Sciences [PDF]
, 2019 Satellite altimetry is a radar technique for measuring the topography of the Earth’s surface. It was initially designed for measuring the ocean’s topography, with reference to an ellipsoid, and for the determination of the marine geoid. Satellite altimetry has provided extremely valuable information on ocean science (e.g., circulation surface ...

Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Differences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave
