They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater within 13-14 days after collection. For details, see document QF2022-071SAL*.xlsx. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. 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 F. Whitney. For details see document QF2022-071_NUTS*.xlsx. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in cryovials in liquid nitrogen onboard, then transferred to -80C storage in the lab until analysis. Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner Trilogy 7200-000 fluorometer calibrated wtih commercially pure chlorophyll a standard (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 at IOS in Room 2423 3 weeks after the cruise. Variability is assessed as the CV% (std dev / mean*100). Chlorophyll values ranged from 5.94-12.46 ug/l in 4 samples. 0 samples were below Minimum Limit of Detection (
