摘要

Anomolies in surface wave patterns observed on SEASAT Synthetic-Aperture Radar (SAR) imagery over Cobb Seamount are examined. These anomalies are the surface expression of currents interacting with the seamount. The wavelength of the imaged surface patterns are extracted with advanced SAR digital image processing techniques. Nine of the ten detected wavelengths match the expected spectral wavelength envelope of the internal waves that are calculated using oceanographic data. The results show that the wavelengths of the surface pattern imaged are actually the surface manifestation of internal waves on a subsurface density interface. The internal waves are created by current flow over and around Cobb Seamount disturbing the density interface. (Author)
