This item includes summary logs (including flowmeter logs), detailed logs, and bathythermograph observations. Summary of route: The cruise begins at 31° 10'n, 67° 31'w, near Bermuda. They sail west and south into the Caribbean sea and then into the North pacific Ocean. They continue west until they are near Hawai'i, then head northwest into the Bering Sea. They travel south and further west across the North Pacific Ocean, ending at 34° 49'n, 139° 58'e, off the coast of Japan. Summary logs tracking temperatures from February 16 to December 9, 1964 are also included. These include the following information: date, station number, time, coordinates, and temperature. Flowmeter summary logs record the following information: Station, type of tow, reading (revs.), length (min.), Revs/min., wind force, sea condition, vol. H20 filtered, and remarks. The detailed logs are from February 16 to June 23, 1964 and include the following information: cruise number, station number, date, type, 1M net in, out, 1M meter reading, 1/2M net in, out, 1/2M meter reading, coordinates, median local time, 1M length tow, 1/2M length tow, wire angle at depth, corrected depth, corrected depth, 1M displ. vol., 1/2M displ. vol., corrected displ. vol., vol. H20 filt. 1M, vol. H20 filt. 1/2M, comments (whether or not the haul was successful), net clogged, net tears, No. bottles used, surface temp. (occasionally), and observer. The back (verso) of the detailed log sheets records BT slide no., depth, temperature, salinity in a table. Some detailed logs sheets include time-depth recorders (made by Benthos, Inc), which are approximately 3 inches in diameter.
