Samples were analyzed in the lab (5 to 7 days after collection) 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 1965). For details see worksheet “Total-chl” in file 2010-20_CHL*.xls. Phaeopigment data are provided for information only and no quality flags are assigned to them. Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965) with modifications by Culberson et al. (1991). Samples were analyzed using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 950 Colorimeter. All samples were analyzed at sea. File 2010-20oxy*.xls includes the raw data and duplicate analysis. Salinity samples were collected in glass bottles and analyzed on Guildline Autosal model 8400B, S/N 69086, at IOS. Salinometers are standardized with IAPSO standard seawater. Full results are in file 2010-20-sal*.xls. Nutrient samples were collected in plastic tubes and stored frozen and later analysed at IOS using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). File "QF 2010-20nuts*.xls" includes the raw data and an analysis of duplicates. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

Similar problems were noted when the same sensor was used during cruises 2010-36 and 2010-14 in July and August 2010. Using an appropriate recalibration brought those casts into reasonable agreement with the other casts. For casts without titrated dissolved oxygen sampling, a decision on how to recalibrate was based on the noise level in the raw oxygen voltage. The casts with the offset all had a higher noise level for all three cruises known to have had this problem. ************************************************************************************ *CALIBRATION $TABLE: CORRECTED CHANNELS !
