They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater within 3-55 days after collection. For details, see document QF2023-010SAL*.xlsx. Chlorophyll samples were filtered onto 25mm GF/F filters after collection, and immediately frozen and in liquid nitrogen in cryovials and stored in a -80C freezer until analysis.stored until analysis. All samples were returned to the Institute of Ocean Sciences and analyzed 1-14 weeks after the cruises 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. Chlorophyll samples were analyzed at IOS in Room 2423 1-10 months after the cruise. For further details on methodology, see document QF 2023-010_CHL*.xlsx Methodology sheet. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks and 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, J. and Whitney, F.

Surface samples were taken from a Niskin bottle held just below the surface. Oxygen:Dissolved, Conductivity and Fluorescence:URU:Wetlabs data are nominal and unedited except that some records were removed in editing temperature and salinity. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. This type of sensor is usually found to read low by a few %. CTD salinity near the bottom compares reasonably well with deep samples. CTD fluorescence showed the usual pattern of reading higher than extracted chlorophylls samples, CHL<2ug/L and gradually dropping until it was about 50% of CHL when CHL>10ug/L.
