Pressure is from reversing thermometers. Sample collection methods: -------------------------- Sea Water Temperature: - Reversing thermometers mounted on bottles. Salinity: - Collected in bottles. Dissolved Oxygen: - Collected in bottles. Reactive Nutrients (Phosphate, nitrate, silicate): - Collected in bottles 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 300 m or greater. The accuracy of protected reversing thermometers is believed to be +-0.02C. Salinity determinations were made at sea with a Guildline salinometer. Accuracy using duplicate determinations is estimated to be +-0.002 ppt. 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 micro-Winkler procedure of Carpenter (1965) with a starch end-point tritration. Nutrient samples were analyzed aboard ship by the use of a Technicon AutoAnalyzer using methods described in Barwell-Clarke and Whitney, 1996. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. . References: 1. Carpenter, J.H. 1965. The Chesapeake Bay Institute Technique for the Winkler Dissolved Oxygen Method.
