They sail through the Mozambique Channel, the Indian Ocean, and the Philippine Sea. Sample data sheets include the following information: ship-cruise, ship station, sample and number of samples, coordinates, date, local start and finish time, duration, wire angle, TDR no., corrected depth range, type tow, opening-closing, sampler type, ship speed, TSK flowmeter no. and reading, temperature, salinity. Logs also include the following environmental data: surface water temp., air temp., sky conditions, cloud cover, sea conditions, wave height, wind speed, water transparency, BT slide info, BS slide info, Hydro station no. and type, surface salinity sample no., core no., depth to bottom, other sample information, comments (successful tow? If not, why?), observer name. The back (verso) of some these forms records wire angle and hydro station data. Some sheets include time-depth recorders, (made by Benthos, Inc), which are approximately 3 inches in diameter. Plankton sample log sheets record IBM serial number, ship/cruise, sample number, no. of samples, coordinates, upper sampling depth, deeper sampling depth, date, time, duration, device, mesh size, type tow, vol. water filtered, speed, sea state, temperatures, calibration, salinity, wind, wire angle, conditions, depth to bottom, hydro station data, flowmeter reading. Dial settings for 12 kc an d3.5 kc pdrs each watch and at any change settings listed below are the new settings.
