Examination of springtime ice drafts obtained from submarine profiles in a narrow band of the western Arctic Ocean from offshore Alaska to 89°N indicates that the mean ice draft decreased 1.5 m between the mid-1980s and early 1990s. No similar trend

The effectivity of multichannel Wiener filters to improve images obtained with passive microwave systems was investigated by applying Wiener filters to passive microwave images of first-year sea ice. Four major parameters which define the filter were

An aircraft data set of coincident Ka band (33.6 GHz, vertical polarization) passive microwave images and aerial photographs acquired in the Chukchi-Beaufort Sea region in March 1983 was analyzed to evaluate radiometric signatures of deformational fe

Polynomial trend surface analysis was applied to three AVHRR images to determine whether regional trends in image radiance can be removed with this procedure. Results suggest that trend surface techniques can be effective in removing region-scale var

Results are presented of a series of coordinate special sensor microwave imager (SSM/I) underflights that were carried out during March 1988 with NASA and Navy aircraft over portions of the Bering, Beaufort, and Chukchi seas. NASA DC-8 AMMR data from

Numeric analysis of otolith morphology provides vital information to commercial fisheries concerning the age distribution, racial origin, and, to some extent, the environmental history of fish stocks. Conventional methods used to retrieve these data,

Students who take four or five courses simultaneously frequently feel they must “sacrifice” or dilute time from one course for another, especially during exam periods. To alleviate this attention-dilution problem, we developed a logistical format
