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 for 24 hours and analyzed at sea 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). For details see file QF2010-14CHL*.xls. Phaeopigment data are provided for information only and no quality flags are assigned to them. Oxygen samples were analyzed at sea using an automated Winkler titration system with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). The titration system consists of a Brinkmann 665 Dosimat, a UV light source and a UV detector with a 365nm filter custom built by Scripps Institution of Oceanography. For details including a duplicate analysis, see document 2010-14oxy*.xls. Salinity samples were collected in glass bottles and analyzed at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. See file 2010-14-sal.xls for analysis output. For information on precision see 2010-14-sal-duplicates.xls. Nutrient samples were collected in plastic tubes. Most samples were analyzed frozen at IOS using an Astoria autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). Deep silicate samples (400m and below) were analyzed cool at IOS. For full data and details on nutrient duplicates and precision see file QF2010-14nuts*.xls. 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 2010-14 DMS Report.doc and for data see DMS 2010-14 summary.xls. References: 1. Carpenter, J.H. 1965.

The quality of the SBE Dissolved Oxygen data is lower than usual for both sensors because recalibration was based on observations from very few casts, and the fits of bottles against CTD produced significantly different fits for some casts from others. Similar problems were found in sensor #1176 (CTD#0506) on some other 2010 cruises and appear to be associated with CTD communication problems. For details see the processing report 2010-14-proc.doc.
