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. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. Complete documentation on DIC and ALK sampling, analysis and precision estimates can be found in the Carbon Excel file from the cruise located in the cruise "DOC" directory. . References: 1.

Canadian Technical Report of Hydrography and Ocean Sciences, No. 182, 43 pp. ------------------------------------------------------------------- Salinity accuracy The post-cruise calibration suggests that the sensors were reading lower than was shown in the bottle comparison, but since there is likely a source of error besides sensor drift, the bottle comparison was used to recalibrate. There remains some doubt about the CTD salinity which may be low by up to 0.004psu. ------------------------------------------------------------------- Pressure 2001.4 - Large DIC replicate difference but analysis looked fine.
