Analysis methods: ----------------- Chlorophyll samples are collected 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 Model 10 fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. Chlorophyll samples were analyzed on board ship. Oxygen samples are analyzed at sea 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. Salinity samples are collected in glass bottles and analyzed at IOS on Guildline model 8400B Autosal Salinometers which are standardized with IAPSO standard seawater. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using an Astoria autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2007-15_NUT.pdf. NOTE: All Phosphate:Bottle data are flagged “4” because new equipment caused contamination ranging from 0.07 to -0.33 µmol/l PO4. Phosphate data were recovered by comparing to archived data below 1000 dbar at each station and correcting accordingly. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2007-15_DMS_report.pdf. For details on duplicates see file 2007-15_DMS.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. For duplicates and precision of DIC and ALK samples see files 2007-15_DIC.pdf and 2007-15_ALK.pdf respectively. References: 1. Carpenter, J.H. 1965.
