The value looks a little out of line in COMPARE. Sample #334: Dissolved Oxygen: Some confusion because program rejected the flask number; unknown whether a correction was made to the volume. The value seems ok in COMPARE. Analysis methods: ----------------- Chlorophyll samples were analyzed at IOS using a Chemistry Turner 10 AU fluorometer which was calibrated using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see worksheet “Precision” in file QF2008-50CHL.xls. Oxygen samples were analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). Samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 900 Colorimeter. For details on precision see file 2008-50-DO-duplicates.xls. Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal at IOS. Salinometers are standardized with IAPSO standard seawater. See file 2008-50-sal-duplicates.xls for information on precision. Nutrient samples were stored frozen and later analysed at IOS using an Astoria-Pacific analyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file QF 2008-50nuts.xls. References: 1. Carpenter, J.H. 1965. The Chesapeake Bay Institute Technique for the Winkler Dissolved Oxygen Method.

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 a correction factor, which was based on assumptions that deep offshore transmissivity from a June 2009 cruise should be about 62%/m and that drift was linear with time between March 2008 and July 2009. The corrections produced reasonable results for all cruises in that time period. For details on how the correction factor was derived see: OSD_Data_Archive:\Cruise_Data\DOCUMENTS\Transmissometer 1005DR Corrections.doc These data should be considered estimates. ********************************************************************************* *CALIBRATION $TABLE: CORRECTED CHANNELS !
