The Arctic and sub-Arctic are defined in terms of marine environment. Differences in biological productivity between the areas are discussed, with consideration of the chemical and physical factors involved. Plankton production and biology, benthonic and littoral fauna, and fishes and marine animals present problems related to North American fisheries and Eskimo needs. In each case problems are listed for future study, a discussion of systematic and zoogeographic problems closing the report. Maps show (1) zones of the marine environment, (2) bathymetry, and (3) major currents of northern seas. Diagram illustrates the biological cycle in arctic and subarctic marine zones.
