Sample_Number 591: OXY: Both reps suffered from poor titrations that had no endpoints. The values are flagged as a 5 and the values padded. Sample_Number 592: OXY: Niskin top valve was completely open. Very messy titration curve led to a very ambiguous endpoint. Sample_Number 595: OXY: Messy curve near endpoint. Endpoint ambiguous. Sample_Number 597: OXY-1: Niskin spigot was open prior to sampling. Sample_Number 607: OXY: Replicate value not reported. OXY-1: Bubble on lens. There was no endpoint. Just a short straight line. Sample_Number 609: OXY: Endpoint was ambiguous due to a messy titration Sample_Number 610: OXY: Niskin bottle spigot was leaking prior to sampling Sample_Number 612: OXY: Niskin bottle spigot was leaking 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 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 a controlled temperature lab. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2013-18CHL*.xls. 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 QF2013-18OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with disposable plastic inserts 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 58 to 76 days after collection. Full details including a duplicate analysis are in file QF2013-18SAL*.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 raw data, precision and duplicate details see file QF2013-18nuts*.xls. 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 2013-18 DMS Report.doc and for data see "DMS summary (2013-18 data)*.xls." References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

For events #1-39 channel Fluorescence:URU:SeaPoint was removed due to a malfunction. For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". Based on the recommendation from SeaBird, the method for calibration of SBE Dissolved Oxygen concentration was changed from that used for 2011 and some 2012 cruises. For more information see the SeaBird Application Note #64-2, June 2012 revision. Based on a precision study run by the Dissolved Oxygen post-cruise analyst, the titrated values of dissolved oxygen are only reported with 2 decimal places. The two CTD salinity channels differed by about 0.006 with one reading lower than bottles and the other higher. Delay in analysis likely caused some evaporation of samples, so the two salinity channels are likely reading higher than the comparison suggests. The little information available suggests that there has been little calibration drift in the primary salinity. For details on the processing see the report: 2013-18_Processing_Report.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 !
