Sea Ice Lead Statistics from Satellite Imagery of the Lincoln Sea during the Iceshelf Acoustic Exercise, Spring 1990

Abstract : During March and April of 1990, the Remote Sensing Branch collected Advanced Very High Resolution Radiometer (AVHRR) satellite imagery of the Lincoln Sea and Fram Strait in support of the ICESHELF and ICEX acoustic exercises. The Lincoln Sea imagery was analyzed for sea ice lead statistics using a new method based on the Hough transform. Products of the analysis such as lead orientation rose diagrams, lead spacing statistic, and the area covered by leads, are presented here along with the imagery from which the products were derived. Icemotion vectors for three time periods produced by an automated ice motion algorithm are also shown. Imagery of the Fram Strait is included in the appendix. Keywords: Acoustic, Satellite, Exercises.
