Four Synthetic Aperture Radar (SAR) images were collected during the Labrador Ice Margin Experiment (LIMEX) in March 1989 to study mesoscale ocean features over the Newfoundland shelf. Ice floe movement is detected by displacement in the first two images collected on consecutive days. Streamfunction maps of ocean currents are drawn using an objective method after direct wind-driven components are removed. The general flow pattern shows the inshore branch of the Labrador Current to be isolated from the seaward flow over the northern edge of the Grand Banks, in agreement with the mean circulation detected in NOAA satellite images for 3 years by the same method. Ice distribution in the SAR images implies mesoscale features much richer than those in the objectively drawn flow field. It is difficult to detect ice movement in the images with two day separation, because no persistent ice feature is identified in the study area. It is suggested, during the ERS-1 ice mission, to take airborne SAR images one day before or after a satellite pass for ocean current detection from ice floe movement. ¿American Geophysical Union 1991 |
