Sample_Number 385: OXY: Small bubbles in flask Sample_Number 386: OXY: Bubble in flask Sample_Number 390: OXY: Duplicate samples both had bubbles while stirring leading to ambiguous endpoints and poor replication. Samples were not included in the precision analysis due to this problem. Sample_Number 394: OXY: Messy titration curve. Endpoint ambiguous. Sample_Number 400: OXY: Duplicate sample flask was broken prior to sampling. Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -80C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner 10AU fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed on board ship during the cruise or at IOS in Room 1409 about 7 weeks later. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2014-19CHL*.xls. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. Oxygen samples were analyzed at sea using an automated Winkler titration system (Brinkmann Dosimat model 665 for titrations, Dosimat model 865 for dispensing standards 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 QF2014-19OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Ltd. and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab at IOS on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 4 to 19 days after collection. For details including a duplicate analysis, see document QF2014-19SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples was collected and frozen immediately. Another set of samples from 400m and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis. They were analyzed using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For details see document QF2014-19nuts*.xls. DMS samples were analyzed at sea. For details on the collection and analysis of the DMS data see file 2014-19 DMS report.doc and for data see "DMS summary (2014-19 data)*.xls." The minimum detectable level for DMS is 0.10 nMol/L, so “0” values should be interpreted as <0.10nmol/L. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". Post-cruise calibration reports indicate that the primary temperature and conductivity sensors had insignificant drifts. Dissolved oxygen was calibrated using the method described in SeaBird Application Note #64-2, June 2012 revision, except offsets in the fit are allowed.
