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 fresh on board using a Technicon AAII auto- analyzer following methods described in Barwell-Clarke and Whitney (1996). The nutrients were analysed fresh at sea, by Wendy Richardson Precision was determined by analyzing replicate samples drawn from one Niskin. Pooled standard deviation of pairs of samples (Sp) was calculated by: Sp = SQRT{sum (d*d)/2k} where k = no. of pairs and d = difference between pairs Sp for nitrate for the range 1.5 to 45.3 uM was 0.08 Sp for silicate for the range 10.6 to 153.2 uM was 0.16 Sp for phosphate for the range 0.44 to 3.25 uM was 0.017 Accuracy was determined by using commercially available standards from WAKO Chemicals (Sagami Chemical Company of Japan). The values were within 0.77 % of the 20 uM Nitrate Standard and 0.72 % of the 100 uM Silicate standard. 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 10-AU-005-CE fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. NOTE: All Chlorophyll samples were filtered within 4 hours of being sampled unless otherwise reported. Only 1 sample per cast was collected in duplicate. References: 1. Carpenter, J.H. 1965.
