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 which is calibrated annually with commercially pure chlorophyll a (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 in June or in July-August at IOS in a controlled temperature lab. A number of samples were analyzed on a different fluorometer (plankton lab) and values seem to be slightly lower than those analyzed on WP fluorometer. These are flagged. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2013-17CHL*.xlsx where * with the most recent date is the most recent update. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. Oxygen samples were analyzed at sea on 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 QF2013-17OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 22 to 40 days after collection. Full details including a duplicate analysis are in file QF2013-17SAL*.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 on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". The CTD salinity was lower than bottle salinity by an average of ~0.0017. The Dissolved:Oxygen:SBE data are considered of lower quality than usual which is likely due to noisy secondary temperature and/or problems in the secondary plumbing. Problems were less severe during bottle stops except for casts #18, 19 and 22 from which the SBE DO channel was removed. For details on the processing see the report: 2013-17-proc.doc. --------------------------------------------------------------------------------- WARNING: SeaPoint Fluorometer #2228 malfunctioned during the latter half of 2013. There were large values at great depth that got steadily higher through the year until it was removed from service. The data have been left in the file so researchers can see the shape of the profile. Comparison with extracted chlorophyll is recommended. *CALIBRATION $TABLE: CORRECTED CHANNELS !
