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). 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. chl a filtered on board (Jeri Butcher), not analysed on board Chlorophyll analyzed by S.
