Abstract (EN):
The use of an ERS-1 SAR fast delivery image in near real-time for guiding an oceanographic cruise in search of internal waves is discussed. Different image navigation methods are presented and compared. A simple method for predicting the position of internal waves up to four days after image acquisition is presented. The reliability of the prediction method is assessed by comparing the times at which internal waves were observed to arrive at several positions on the Portuguese shelf, with predictions derived from an automatically navigated image.
