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: RI2, Sample Number: 633, Silicate corrected using Bottle salinity. ===================================================================================== Analysis methods: ----------------- Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs fluorometer which was calibrated in May 2007 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see worksheet “Precision” in file QF 2008-26CHL.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 2008-26-duplicates-DO.xls. Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal or a Guildline Portasal 8410A. Salinometers are standardized with IAPSO standard seawater. See file 2008-26-sal-duplicates.xls for information on precision, and note the warning given below. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file QF 2008-26nuts.xls. DMS data are provided by C.S. Wong and researchers are asked to contact him before using them. 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 2008-26 DMS Report.doc.

Canadian Technical Report of Hydrography and Ocean Sciences, No. 182, 43 pp. WARNING: The salinity analyses done on a Portasal salinometer at sea are considered unreliable. Many duplicate samples were run using an Autosal at IOS and the Portasal. The results showed that the Portasal read much lower than the Autosal for those samples analyzed on the Portasal on June 5th. For other days the Portasal was low by an average of 0.0016 but there was a lot of noise in the comparison with many values within 0.001 of the Autosal, while others looked unstable. (For more detail see file 2008-26-bottle-salinity-port-auto-dups.xls.) Autosal values have been selected for Salinity:Bottle where possible. Where there are no Autosal values, the Portasal values were used, but were all flagged "c", except for those from June 5th which have been flagged "d". *CALIBRATION $TABLE: CORRECTED CHANNELS !
