On Some Planktonic Protozoa Taken from the Track of the Drift Station ARLIS I, 1960-61
Twenty-six species of protozoans identified from ARLIS I plankton collections are discussed with respect to their geographic and depth distribution. Diversity of species and abundance of organisms were both greater in the eastern than in the western collections. Plankton was generally sparse in the...
