NORTH PACIFIC OCEANOGRAPHIC CRUISE BY "HUGH M, SMITH (Cruise 30): The Hugh M. Smith during a 6-week participation cruise in Operation Norpac vestigated the oceanography of the North Pacific in an area between latitudes 25 N. and 50° N. and longitudes 180 and 158° W. The weather was fair throughout the cruise, except for a brief period of rough weather on the first leg (180th meridian) and fog in areas of sudden temperature drop where the North Pacific current fringed on sub- arctic waters at about 45 N. latitude. A total of 79 oceanographic stations were oc- cupied at depths ranging from the surface to 8,000 feet. Plankton hauls were rou- tinely made and the Isaac-Kidd trawl was operated very successfully. Surface troll- ing produced 7 albacore at stations in the vicinity of 45 N. latitude and 157-172^ longitude. The results from Norpac, a multiple-ship operation involving vessels of U. S. Fish and Wildlife Service Pacific Oceanic Fisheries Investigations, Scripps Institution of Oceanography, the Univer- sity of Washington, the Pacific Oceano- graphic Group of Canada, and severalJa- panese agencies should be invaluable in furthering an understanding of North Pa- Cruise 30 of the Hugh M. smith (Norpac), JiUy 15-Aug. cific midsummer oceanographic conditions 28,1955. and their relationship to meteorology and the distribution of albacore and salmon. The Hugh M- Smith left Pearl Harbor on July 15 and returned to that port on August 28. The wheel watch mainiained a careful lookout for tuna schools, bird flocks, and scattered birds and mamals. Except for the numerous schools of flying fish in the southern part of the area, fish were sighted on o
