Chlorophyll and Phaeo-Pigments precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2010-13_CHL.pdf. 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 see file 2010-13_OXY.pdf Salinity samples were collected in glass bottles and analyzed at sea using a Guildline Portasal (#58879) or at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. For information on precision see 2010-13_SAL.pdf. 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 (400 dbar and below) were analyzed cool at IOS. For details on nutrient precision see file 2010-13_NUT.pdf. NOTE: FROZEN SAMPLES WERE ACCIDENTALLY THAWED FOR 2 DAYS AT ROOM TEMPERATURE THEN STORED COOL UNTIL ANALYZED. 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 2010-13_DMS_Report.pdf. For duplicates see 2010-13_DMS.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogren ion concentration scale was determined photometrically and is reported at 25C and surface pressure. For duplicates and precision of DIC, ALK and pH samples see files 2010-13_DIC.pdf, 2010-13_ALK.pdf, and 2010-13_pH.pdf respectively. References: 1. Carpenter, J.H. 1965.

In August 2010 a study was made of transmissivity that led to a decision to apply post-processing corrections to all cruises between March 2008 and June 2010. Transmissivity data from this cruise were corrected by multiplying the original values by correction factor 2.5, which was based on the assumption that deep offshore transmissivity should be about 62%/m. For details on the transmissometer post-processing see: Transmissometer_1005DR_Corrections.pdf These data should still be considered nominal. ********************************************************************************** For details see the processing report 2010-13-proc.pdf. 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.
