Deformation of the Arctic Ocean Sea Ice Cover Between November 1996 and April 1997: A Survey
Quasi-linear features of the scale of kilometers to hundreds of kilometers can be observed in the high-resolution deformation fields of the sea ice cover produced by the RADARSAT Geophysical Processor System.
Diurnal Variations of Melt Regions on the Greenland Ice Sheet
Melt regions on Greenland ice are mapped daily with the SeaWinds wideswath Ku-band scatterometer on the QuikSCAT satellite.
Observation of Sea Ice Surface Thermal States Under Cloud Cover
Clouds interfere with the distribution of short-wave and long-wave radiations over sea ice, and thereby strongly affect the surface energy balance in polar regions.
Evolution of the Arctic Ocean Sea Ice Cover: November 1996-April 1997

Sea Ice Thickness from Kinematics
High resolution 3-day surveys of the Arctic Ocean are currently being obtained using the Canadian RADARSAT synthetic aperature radar with its wideswath ScanSAR mode.

Recent Changes in Arctic Ocean Sea Ice Motion Associated with the North Atlantic Oscillation
Examination of a new ice motion dataset of the Arctic Ocean over a recent eighteen year period (1978-1996) reveals patterns of variability that can be linked directly to the North Atlantic Oscillation.
Ice Motion Over Lake Vostok
Ice motion over Lake Vostok is measured using repeat-pass Synthetic Aperture Radar (SAR) interferometry.
The Arctic Ocean Perennial Ice Zone
This study shows that: 1) the NSCAT backscatter fields provide an estimate of the PIZ coverage of the Arctic Ocean; and, 2) the decrease in PIZ area over the winter gives an indication of the PIZ area exported through Fram Strait.
Shipborne Scatterometer Measurements of Great Lakes Ice

Great Lakes Ice Cover Classification and Mapping Using Satellite Synthetic Aperture Radar (SAR) Data
Owing to the size and extent of the Great Lakes and the variety of ice types features found there, the timely and objective qualities inherent in computer processing of satellite data make it well suited for monitoring and mapping ice cover.
Shipborne Scatterometer Measurements of Great Lakes Ice
The Jet Propulsion Laboratory C-band polarimetric scatterometer was used to measure radar backscatter of Great Lakes ice during the 1997 Great Lakes winter experiments.
