Zooplankton of Foxe Basin in the Canadian Arctic
Zooplankton collections from 100 stations in Foxe Basin and immediately adjacent waters of the eastern Canadian arctic, made in 1955, 1956 and 1957, are considered. Available information on physical oceanography of the region is discussed, especially factors with apparent direct relationship to plan...
