Salinity: - Collected in bottles. Dissolved Oxygen: - Collected in bottles. Nutrients - two plastic and two glass vials Analyzes methods: ------------------------- Temperatures at depth were measured by deep-sea reversing thermometers of German (Richter and Wiese) and/or Japanese (Yoshimo Keiki Co.) manufacture. Two protected thermometers were used on all bottles, and one unprotected thermometer was used on each bottle at depths of 250 m or greater so that depths could be calculated. The accuracy of protected reversing thermometers is believed to be +-0.02C. Salinity determinations were made at sea with a Guildline model 8400 lab salinometer. Depth determinations were made using the "depth difference" method described in the U.S.N. Hydrographic Office Publication No. 607 (1955). Depth estimates have an approximate accuracy of +-5 m for depths less than 1000 m, and +-0.5% of depth for depths greater than 1000 m. The dissolved oxygen analyses were done in the shipboard laboratory by a modified Winkler method (Carpenter, 1965). Nutrient samples for nitrate, phospahte and silicate were drawn unfiltered into two plastic and two glass vials and frozen in an upright position. Following the cruise samples were analyzed using a Technicon auto-analyzer under contract to Seakem Oceanography Ltd. The maximum duration between sample collection and analysis was six months. NOTE: The nutrient samples collected during this cruise were accidentally thawed for three days in a closed freezer and then re-frozen. Obviously erroneous data in this case have been omitted; however the remainder may also be invalid. References: 1. R.E. Thomson, W.S. Hugget and L.S.C. Kuwahara. 1980.
