In this proposal we seek to explore new potential oceanographic applications of TerraSAR-X standard modes, with particular emphasis to near shore dynamics and related to air-sea interactions studies. The project relies on various in situ studies of both near shore and offshore dynamics already scheduled for the beginning of TerraSAR mission, integrated in on going funded projects such as the U.K. NERC CASIX and the Portuguese FCT SPOTIWAVE-II. We aim to compare TerraSAR-X data with such in situ measurements and further satellite synergistic data, hoping to contribute to stimulate new oceanographic and coastal applications of SAR. It is anticipated that those studies will not only be useful for scientific inter-disciplinary results, but will also provide useful calibration and validation results for the TerraSAR-X mission.
Satellite remote sensing high resolution current information is needed for many coastal applications traditionally studied with in situ and laboratory measurements, wave tank experiments and numerical modelling. Examples of applications where TerraSAR-X data may play an important and innovative role are testing possible modelled scenarios of oil slick disaster in near shore regions, and monitoring near shore strong currents potentially hazardous to men and navigation. In this project we will look at the potential of TerraSAR-X data to observe such phenomena and report recommendations for developing new products and stimulate the Earth Observation Market.
We are hoping to compare planned in situ observations of film slicks and internal waves, in the frames of CASIX and SPTIWAVE-II projects with TerraSAR-X images in ScanSAR and Strimap modes. We will also look for match-up between SAR backscatter (integrated to a nominal altimeter footprint) and the altimeter differential mean slope algorithm (developed within CASIX) to detect slicks and apply semi-quantitative models of air-sea flux in the presence of slicks. ScanSAR and Stripmap modes are likely to provide new insights into internal wave morphology (when compared to in situ measurements in the frame of SPOTIWAVE-II) and polarimetric modes are likely to help to discriminate between oceanic and atmospheric features. Finally we expect the enhanced spatial resolution of TerraSAR-X, compared to other missions, to be very valuable to observe near shore small scale dynamics, such as rip currents and river plumes.
