A preliminary survey on the distribution of temperature, bottom topography and ichthyofauna on the New Year Bank in the Solomon Sea, about 45 nautical miles to the south of Guadalcanal, was carried out by the training ship "Kakuyo-maru" of the Faculty of Fisheries, Nagasaki University, on November 5th to 8th, 1978. The following results were obtained. 1) Along the east and south margins of the bank, a thermoline was observed between the layers 200m and 300m below the surface. 2) The bottom topography on the bank was very rugged, especially in the central part where the difference in altitude of ups and downs was as big as 23m. 3) A number of echos of fish schools were recorded on the bank. They were especially dense and numerous just above the tops of ups in the southern half of the bank. 4) A total of 30 fish species belonging to 14 families were caught by hand-line fishing. Groupers, pigfaces, and snappers were commercially important fishes among them.
