High Resolution Satellite Observations of Mesoscale Oceanography in the Tasman Sea 1978-79.

Abstract

Nearly 1000 standard infra-red photographic images have been received and of these, 273 images have been received on computer-compatible tape. It proved necessary to digitally enhance the scene contrast to cover only a select few degrees K over the photographic grey scale appropriate to the scene-specific range of sea surface temperature (SST). 178 images have been so enhanced. Comparisons with sea truth are made and we conclude that SST, as seen by satellite, does provide a good guide to the ocean currents and eddies off East Australia, both in summer and winter. This is in contrast, particularly in summer, to SST mapped by surface survey, which usually lacks the necessary spatial resolution.
