All samples were returned to the Institute of Ocean Sciences and analyzed 3-4 months 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 further details on methodology, see document QF2024-041_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, 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 QF2024-041_OXY*.xlsx. Salinity samples were collected in 200mL or 250mL 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 5-17 days after collection. For details see document QF2024-041SAL*.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 QF2024-041nuts*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

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.
