This data set formed the basis for estimating sea ice floe velocities covering two spring whaling seasons with markedly different rates of success from March to June in 2000 and 2001 in the Chukchi and Beaufort Seas near Barrow, Alaska. Synthetic Aperture Radar (SAR) images from the RADARSAT and the European Remote Sensing Two (ERS - 2) satellites and broadband visible (VIS) and infrared (IR)images from the Advanced Very High Resolution Radiometer (AVHRR) satellite were used. Sea ice floe velocity and sea ice reflectance are the parameters used in this data set.

The temporal resolution of these images were from one to seven days with a mean of three days. The spatial resolution was 30 m to 1.6 km. These images were georeferenced and reproduced in Microsoft PowerPoint format; thus, PowerPoint is necessary to view these images. Data and browse images are available via FTP.
