(deg min) *COMMENTS Samples Number 10, 28, 102, 158, 224, 310, 551, 638: Oxygen:Dissolved:Bottle - Flags explained in Analysis methods below. Sample Number 159: Salinity:Bottle - lid loose; Chlorophyll:Extracted:Bottle - too low for surface chlorophyll. Sample Number 312: Salinity:Bottle - insert came out very easily; may not have provided a good seal. Sample Number 360: ALL SAMPLES: Entire cast believed offset by one place due to lanyards being misplaced; the data were rearranged so that Bottle Number 1 is the bottom bottle. Sampling Methods are expressed with the following codes ------------------------------------------------------- ROS - Rosette sample collected from approximately 5m depth. LOOP - Sample drawn from a pumped seawater supply provided to the ship laboratory from a nominal depth of 4.5 metres. Analysis methods: ----------------- Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs 10AU fluorometer which was calibrated on May 13, 2009 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2009-10_CHL_precision.pdf. Oxygen samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 765) and a PC 950 Colorimeter. For information on precision see file 2009-10_OXY_duplicates.pdf. The thiosulphate titer of 0.709 obtained during standardization was low and out of range leading to a suspected overestimate in Oxygen:Dissolved:Bottle value of ~2.5%. This is believed to be due to either a bad batch of standard or incorrect calibration parameters (temperature or volume dispensed). Comparison to the Oxygen:Dissolved:CTD data confirmed the likely Oxygen:Dissolved: Bottle data overestimate using the original 0.709 titer. The Oxygen:Dissolved:Bottle data were thus recalculated using the mean thiosulfate titer for the year (0.721). Recalculated results are consistent with a post-cruise calibration of the Oxygen:Dissolved:CTD data. All samples are flagged "4" since the data are considered to be of lower quality than usual. Salinity samples were collected in glass bottles and analyzed at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. Samples from two casts were analyzed at sea on a Guildline Portasal; there are comments attached to those samples and all were flagged "4". See file 2009-10_SAL_duplicates.pdf for information on Autosal precision. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using an Astoria Pacific autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see files 2009-10_NUT_duplicates.pdf and 2009-10_NUT_precision.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 2009-10_DMS_report.pdf.
