All samples were returned to the Institute of Ocean Sciences after collection. 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 5 weeks after the cruise. For further details on methodology, see document QF 2022-069_CHL_ *.xlsx Methodology sheet. 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 and 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 duplicate analysis, see document QF2022-069OXY*.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 3 - 33 days after collection. For details see document QF2022-069SAL*.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 analyzed using an Astoria-Pacific and the SEAL AA3 following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney.

Fluorometer # 3982 malfunctioned. It was used for events #2-135. Data from the top 20m were lower compared to extracted chlorophyll samples than is usual for this type of sensor. Deep values varied from 0 to high values with noisy sections. Files that include fluorescence may be obtained by sending a request to: PAC SCI IOS Data / Données ISO SCI PAC (DFO/MPO) For events #136-145 fluorometer #3641 was used and performed normally. The data are considered nominal and are unedited except that some records were removed in editing temperature and salinity. 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. Silicate values were corrected if CTD salinity was <25psu.
