Sample_Number 224: CHL: sample lost during analysis. Analysis methods: ----------------- 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 precision analysis, see document QF2024-019_OXY*.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 within 5-15 days after collection. For details see document QF2024-019_SAL*.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 QF2024-019_NUTS*.xlsx. Chlorophyll samples were filtered onto 25mm GF/F filters after collection, and immediately frozen and stored in a -80C freezer until analysis. All samples were returned to the Institute of Ocean Sciences and analyzed 1-2 weeks after the cruise on a Turner Trilogy7200-000 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 QF 2024-019_CHL_*.xlsx Methodology sheet. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values The Ammonium method used at IOS is a modification of the fluorometric technique of Holmes et al., 1999. The method uses a single working reagent and minimizes contamination, can be applied to a large range of ammonium concentrations, and allows for samples to be processed quickly in the field. Samples are collected during the day into vials cleaned with working reagent, and stored in the Cold Room on the Tully. Working standards that bracket the expected sample concentrations are made up daily from seawater low in organic matter, collected on 2023-066, station P23, at 2005m. Samples and standards are spiked with working reagent at the same time, and allowed to incubate for 8-18 hours to maximize fluorescence signal and stability. The fluorescence is then read using a Turner Trilogy fluorometer in raw fluorescence mode. A linear calibration curve is generated from the standards, and the calibration equation then applied to sample fluorescence to determine sample concentration. For further details on methodology, see document QF 2024-019_NH4_*.xlsx All the CTD variables are averaged over the same pressures in order to have one line of data per sample. References: 1.

NOTE: 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. For details on the processing see the report: 2024-019_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CALCULATED CHANNELS !
