Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter is controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples are analyzed frozen or cooled using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996 Nutrient analysis comments from spreadsheet: Samples were collected in glass and plastic test tubes, some were kept cool and some were frozen. Frozen samples were thawed for 1/2 hour in 50 C bath (silicate and nitrate) and in air (phosphate). The following results are from frozen samples for Stations SI03, Argo1, Argo 2, Argo 3, Argo 4, and Argo 5. The results of cool samples are given for Stations P26, P20, P16, P12, P08, and P04. Chlorophyll samples are collected in duplicate in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters are placed in glass scintillation vials and immediately frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract is decanted and measured using a Turner Designs 10-AU-005-CE fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. Chlorophyll analysis comments from spreadsheet: Chlorophyll samples filtered onboard JP Tully by James Zwiers and stored frozen until analysis. Samples analyzed at IOS May '03 by Melissa Hennekes. Fluorometer calibrated August '02. References: 1. Carpenter, J.H. 1965. The Chesapeake Bay Institute Technique for the Winkler Dissolved Oxygen Method. Limmnol. & Oceanogr., 10: 141-143. 2. J.
