Abstract : Airborne tests of multispectral remote sensors have been conducted on eight occasions during July 1966 to September 1968 over the Mississippi Delta area and eastern Gulf of Mexico to determine their usefulness in surveying river, coastal and deep-sea phenomena. Four of these tests were supported concurrently by oceanographic research vessels. Passive remote sensors--principally metric cameras, infrared imagers and microwave radiometers--were flown at 1,500, 5,000, 10,000 and 50,000 feet above sea level. In addition, studies into the relationship between low cloud development and horizontal anomalies in the sea surface temperature field and studies into basic microwave research have been conducted at Texas A and M University. The following features of the Mississippi River were surveyable by remote sensors from aircraft: (1) location of surface frontal zones of convergence, (2) determination of surface water mass type, (3) small scale pattern of mixing, (4) location of internal waves and (5) general outflow pattern shape and extent. A persistent area of apparent upwelling in East Bay between South Pass and Southwest Pass was discovered during the aircraft program. A positive correlation was found between horizontal anomalies in the air-sea temperature difference field and the low cloud coverage over the ocean. (Author)
