The CTD data degrades at about 500m of the downcast. The last part of the downcast and all of the upcast data is non-useable. 19 bottles were tripped and 13 bottles confirmed. There is no way to confirm bottle depths using CTD data comparisons. *********************************************************************** Comments from secondary file: Q:\Cruise_Data\2003-31\ctd\test\2003-31-0066.chl ------------------------------------------------ Average of two samples is reported. Variability is assessed as the % (std dev/mean*100). Note that average variability is usually around 4.5% for total chlorophyll measurements, and some of the chlorophyll duplicates in this cruise vary by more than this. Variabilities greater than 10% have been flagged “c”. ------------------------------------------------------------------ CHL Samples 232, 233 and 234 were flagged "f" by the analyst, but were changed to "c" because of doubts about the depth of bottle firing. ------------------------------------------------------------------- DOX samples 232, 233 and 234 were flagged "c" because of doubts about the depth of bottle firing. 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.
