Abstract

The southern Benguela area of the South Atlantic ocean is characterised by intermittent, wind-induced upwelling. Because of its economic importance related to the fishing industry in this area, the upwelling has been the subject of intense investigation for many years (Hart & Currie, 1960; Shannon, 1969; Visser, 1969; Andrews & Cram, 1969; Schell, 1970; De Decker, 1970; Bang, 1971; Bang, 1973; Bang & Andrews, 1974; Bang, 1976, Shannon, 1979; Shannon, Nelson & Jury, 1980). With the advent of thermal infrared sensors on satellites new avenues have been opened up to investigate this phenomenon. This report describes a number of features of the dynamics of upwelling in the area which have not been noted by conventional means, and attempts to relate them to existing knowledge.
