Physical, Chemical and Biological Data, TASADAY Expedition - Legs I, II, III andIV: Leg I, 5 June-1 July 1973; Leg II, 8-15 July 1973; Leg III, 22 July-4 August 1973; Leg IV, 13 August-6 September 1973

摘要

TASADAY EXPEDITION aboard RV Thomas Washington was a multidisciplinaryoceanographic expedition in the Pacific and Indian Oceans during 1973-1974. This report presents the physical, chemical and some of the biological data, physical and chemical data, all in the Pacific Ocean during 1973. Temperature was measured using paired deep sea reversing thermometers and is reported to hundredths of a Celsius degree. Most Nansen bottles below 100 meters included unprotected (pressure) thermometers for depth determination. Water samples on most stations were collected by Nansen bottles hung on the STD wire in conjunction with STD lowerings. Salinity was determined using an inductive salinometer. Samples from shallow casts were determined by inductive salinometer; conductive bridge was used to determine samples from deep casts. The values, tabulated in parts per thousand (%o), are reported to three decimal places provided the values meet accepted standards. The values are reported to two places when only one determination per sample was obtained or when the accuracy of a particular sample is in doubt.
