Adjustment was made for salinity values (when available) of <= 25 psu. Adjustment equation: Silicate:Corrected = Silicate * [1+((-0.003)*(32-S))] where, Silicate:Corrected = corrected silicate concentration in micromoles/litre Silicate = uncorrected silicate concentration in micromoles/litre -0.003 = salt correction factor 32 = salt concentration of artificial seawater used by the WPG Astoria Pacific continuous flow analyser S = salinity of the sample At Station: BS8, Sample Number: 110, Silicate corrected using CTD salinity. At Station: BS8, Sample Number: 109, Silicate corrected using CTD salinity. ===================================================================================== Analysis methods: ----------------- Oxygen samples were analyzed at sea using 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). For details including a duplicate analysis, see document QF2011-25oxy*.xls. Salinity samples were collected in glass bottles and analyzed on Guildline Autosal model 8400B, S/N 68572, at IOS within a month of collection. Salinometers are standardized with IAPSO standard seawater. Full results are in file 2011-25-sal*.xls. Nutrient samples were collected in 15mL plastic tubes and frozen and later analysed at IOS using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For details including a duplicate analysis see file QF 2011-25nuts*.xls. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

The SBE data are considered of lower quality than normal because 24 scans were averaged in acquisition. These averages may contain spikes that would normally be removed in processing and might be systematic in nature. The pH data have been removed as they are not considered suitable for archiving. For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". SBE DO calibration was done using the method described in the SeaBird Application NOte #64-2.
