Samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner 10AU fluorometer which is calibrated annually with commercially pure chlorophyll a (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed on board ship in a controlled temperature lab. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2011-27_CHL-*.xls. Phaeopigment data are provided for information only and no quality flags are assigned to them. Oxygen samples were analyzed on an automated Winkler titration system (Brinkmann Dosimat model 765 and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). All samples were analyzed at sea. For details including a duplicate analysis, see document QF2011-27oxy*.xls. Salinity samples were collected in 200 mL type ll glass bottles with plastic inserts and screw caps supplied by Ocean Scientific Internation Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater within 2 months of collection. Full details are in file QF2011-27sal*.xls. Nutrient samples were collected in plastic tubes. Most samples were analyzed fresh at sea. A few loop samples were analyzed frozen at IOS. An Astoria analyzer was used following methods described in Barwell-Clarke and Whitney (1996). File "QF 2011-27nuts*.xls" includes the raw data and a precision study. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2011-27 DMS Report.doc. For the data see DMS 2011-27 summary.xls and for the precision study see "std dev of pairs 2011-27.xls". References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". SBE DO calibration was done using the method described in the SeaBird Application NOte #64-2. For further processing details see the processing report 2011-27-proc.doc.
