For details including a precision analysis, see document QF2024-006_OXY*.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 within 18-31 days after collection. For details see document QF2024-006_SAL*.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 Institute 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 QF2024-006_NUTS*.xlsx. Chlorophyll samples were filtered onto 25mm GF/F filters after collection, and immediately frozen and stored in a -80C freezer until analysis. All samples were returned to the Institute of Ocean Sciences and analyzed 1-2 weeks after the cruise on a Turner Trilogy7200-000 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 further details on methodology, see document QF 2024-006_CHL_*.xlsx Methodology sheet. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values The minimum detectable level for DMS is 0.1 nM, so “0” values should be interpreted as <0.1 nM. DMS data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. All samples were run on an 8890 Gas Chromatograph system. For more details on analysis see documents "DMS summary (2024-006).xls". The minimum detectable level for DMSP is 0.1 nM, so “0” values should be interpreted as <0.1 nM. DMSP data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. For more details including method, raw data and duplicates, see document "QF2024-006 DMSP QF file.xls”. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

Sample Number 370: CTD variables are averages of values from Bottles Number 9 to 16. Sample Number 371: CTD variables are averages of values from Bottles Number 17 to 24. Conductivity, Transmissivity and Fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. NOTE: While the SBE 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. 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. Two different CTDs were used during this cruise. The following channels were removed: - PAR: 6,27,28,34,43,45,47,55,61,62,66,70,83,88 - Transmissivity: 61 - Transmissivity:Green: 61,62,66,70,73,74 - Both Fluorometers: 61,62,66,70,73,74,76,79 For details on the processing see the report: 2024-006_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CALCULATED CHANNELS !
