June 1964 B. C. F. Townsend Cromwell Cruise The June 1964 Townsend Cromwell cruise was the fifth of a series of cruises run by the U. S. Fish and Wildlife Bureau of Commercial Fisheries covering a fixed grid to the east of the main Hawaiian Islands for the purpose of determining variations in structure of the water masses and currents of this area. Pacific Project personnel have taken part in four of these cruises. On the June cruise Project personnel maintained daily sunrise to sunset bird observations for a total of 256.2 hours. In addition Project personnel aided on recording weather observations and in taking bathy- thermograph traces. Project personnel included Warren King and Dayle Husted. Upon availability of oceanographic data, an attempt will be made to correlate bird distribution with prevalent oceanographic conditions of the cruise. Warren King Research Assistant U. S.
