DYNAMICS AND MORPHOLOGY OF BEAUFORT SEA ICE DETERMINED FROM SATELLITES, AIRCRAFT, AND DRIFTING STATIONS

摘要

The measurements consist of:(1) high resolution ERTS-1 imagery which is used to describe floe else and shape distri¬bution, short term floe dynamios, and lead and polynya dynamics;(2) tracking by Nimbus 4 of IRLS drifting buoys to provide ice drift Information which enhances the interpretation of the ERTS-1 imagery;(3) Nimbus 5 microwave (1.55 cm wavelength) imagery which provides synoptic, sequential maps on the distribu¬tion of multiyear and first-year ice types;(4) airborne microwave surveys and surface based observations made during 1971 and 1972 in conjunction with the AIDJEX (Arctic Ice Dynamics Joint Experiment) program.
