The oceanography program became the responsibility of the University of Washington's Department of Oceanography; mens was largely the the collection of speci- responsibility of the North Pacific Exploratory Fishing and Gear Research Branch of the Fish and Wildlife Service; and the identification of samples and evaluation of radioactivity was the responsibility of Laboratory of Radiation Biology. Fish and Wildlife Service, Fisheries and the Fisheries the Specialists from the U. Juneau, and from the Research Institute, S. College of University of Washington, were hired for the identification of the fishes and the invertebrates and to conduct salmon surveys. During August 1959 collections and surveys were made in the field. The work last summer was the most intensive study that has been undertaken in this portant because of its region and is especially im- contribution to the present scant amount of information about the area. The fish population was small but the invertebrate collection was large both in respect to number of individuals and to number of species. indentification of the fishes is essentially complete. on the invertebrates is continuing.
