They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater within 7-134 days after collection. For details, see document QF2022-030SAL*.xlsx. Chlorophyll samples were filtered onto 25mm GF/F filters after collection, and immediately frozen and stored until analysis. All samples were returned to the Institute of Ocean Sciences after completion of the timeseries. Samples were analyzed 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 2022-030_CHL*.xlsx Methodology sheet. Nutrient samples were collected but all were lost before analysis. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

Surface samples were taken from a Niskin bottle held just below the surface. For casts with no CTD data available near the surface, Pressure and Depth were entered as 0. These should be considered nominal readings. 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 well with deep samples. CTD fluorescence compared well with extracted chlorophylls samples.
