A duplicate sample for bottle #4, 1000db, (sample #9509) had DO = 0.232 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 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.

The salinometer malfunctioned and data run before and after repair look notably different. The later data has been used for recalibration, but there remain some doubts about it. The SBE dissolved oxygen sensor data were recalibrated differently for the earlier casts. Anoxic conditions during cast #1 may have affected the sensor up to cast #15. All casts from #15 onward were treated the same. The DO comparison with bottles had more scatter than usual. ************************************************************************** *CALIBRATION $TABLE: CORRECTED CHANNELS !
