Though they can be as tall as skyscrapers, internal ocean waves rarely break the surface, making it more difficult to determine their speed. But researchers at the University of Miami have managed to determine the speed of one massive wave using a single satellite overpass, according to a release from the school. Previously, multiple satellite overpasses were needed to determine wave speed. <\/p>\n
The feat was accomplished using a German TerraSAR-X satellite\u2019s radar, which provided a single-pass image. The single-pass image was noisy and required further processing by UM\u2019s Center for Southeastern Tropical Remote Sensing (CSTARS) before the internal wave speed could be determined. <\/p>\n
CSTARS enhanced the internal wave patterns in the image to accurately gauge its wave velocity. Only CSTARS and the German Aerospace Center are currently capable of processing the images correctly to ascertain internal ocean wave speeds. <\/p>\n
The movements of internal ocean waves are important because they move large amounts of heat, nutrients and salt across the ocean, which affect fish, marine industries and global climate.<\/p>\n
