All samples were returned to the Institute of Ocean Sciences and analyzed 11 weeks after the cruise on a Turner Trilogy 7200-000 fluorometer, using methods described in Holm-Hansen et al (1965). Fluorescence readings taken before and after sample acidification were used to calculate chlorophyll and phaeopigment concentrations. For details on methodology, see document QF2022-022_CHL*.xlsx Methodology sheet. NOTE: Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values. Oxygen samples were analyzed at sea using an automated Winkler titration System (Metrohm Dosimat model 876 and a UV light source and detector with a 365nm filter controlled by LV02_876 software designed and constructed by Scripps Institution of Oceanography) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details including a precision analysis, see document QF2022-022OXY*.xlsx. Salinity samples were collected in 200 mL type ll glass bottles with disposable nylon inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 6 - 17 days after collection. For details including a duplicate analysis, see document QF2022-022SAL*.xlsx. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. For samples 400m and deeper a second set of samples are collected and stored cool for silicate analysis. All samples were returned to the Insitute of Ocean Sciences and they were analyzed using an Astoria-Pacific Analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document QF2022-022nuts*.xlsx. The ammonium method used at IOS is a simplification of the fluorometric technique of Holmes et al, 1999. This method applies to a wide range of ammonium concentrations, uses the addition of a single working reagent and reduces contamination. Typically, samples are collected during the day and stored in the cold room. The working reagent is added to standards and samples at the same time, and the fluorescence is read approximately 8 hours later using a Trilogy Fluorometer in Raw Fluorescence Mode. Standards are made in LNSW collected at P22 400m. For full details including a precision study see file QF2022-022NH4*.xls. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

There were 2 WetLabs CStar transmissometers in use during this cruise: Channel Transmissometer refers to sensor #1185DR (650nm - red) Channel Transmissometer:Green refers to sensor #1883DG (530nm - green) For comparison with other Institute of Ocean Sciences cruises, note that the transmissometer wavelength is 650nm unless otherwise stated. NOTE: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. Channel Salinity:T1:C1 was found to be very close to bottle samples. The SBE DO sensor hysteresis setting and calibration appeared to change suddenly between casts #128 and #133. This might be related to problems encountered in the previous cast at the same site as #133. The change was small and principally affected low oxygen values. The later casts were reconverted with different hysteresis parameters. Separate recalibration schemes were applied to the 2 groups of casts. For details on the processing see the report: 2021-022_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
