Paleoceanography, one of the youngest branches of earth sciences, is concerned with the development of oceanic circulation through geologic time. This is a multifaceted and integrated endeavor since none of the subdisciplines is easily separated from the others. The field is holistic in character, and includes the history and effects of bottom, intermediate and surface circulation patterns, planktonic and benthonic biogeographic development and rates of organic evolution, the history of biogenic productivity and dissolution and their effect on sediment distribution and the consequences of sea level change.
Paleoceanography was largely born of the Deep Sea Drilling Project (DSDP) and continues to be nourished by it. Because problems are of global scope, the appetite for new sediment core material is large, and is being supplied by numerous expeditions of DSDP. This article is a brief overview of a number of advances that have occurred in paleoceanography and related fields during the period from 1979 to 1982. Because of page limitations, all publications cannot be cited which is not meant to indicate any lack of importance.
