Nitrate_plus_Nitrate:Bottle - H2S so no nitrate analyzed. Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C prior to analysis. 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. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see file 2011-27_CHL.pdf. 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 file 2011-27_OXY.pdf. Salinity samples were collected in 200 ml type ll glass bottles with plastic inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 5 months after collection. Full details are in file 2011-27_SAL.pdf. 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). See file 2011-27_NUT.pdf for duplicates and precision information. NOTE: July 2013: A correction has been applied to Nitrate_plus_Nitrite:Bottle and Phosphate:Bottle data from deep-water cruises analyzed at IOS between 2009 and 2012. For details see the report: Corrections_to_Nitrate_and_Phosphate_Data_2009-2012.pdf. 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.pdf. See file 2011-27_DMS.pdf for duplicates and precision study. References: 1.

For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. The Oxygen:Dissolved:CTD calibration was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf).
