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. Chlorophyll concentration was estimated from fluorescence of aqueous acetone extracts from filtered samples. Analysis methods generally followed those described in Parsons et al. 1972, however there have been various modifications of filtering and extraction protocols. Contact data originator(s) for details specific to individual time periods. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. . References: 1. Carpenter, J.H. 1965.
