For details including a precision analysis, see document QF2024-034_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 21 days after collection. For details see document QF2024-034_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 QF2024-034nuts*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

Channel pH:SBE was removed from events #1-30 because the cap was left on. Corrections to the pressure and salinity channels were based on post-cruise calibrations. Oxygen:Dissolved:SBE data were corrected by multiplying all values by 1.087 based on the bottle comparison. This is a much larger correction than suggested by the post-cruise calibration, but evidence suggests that there was some contamination of the sensor membrane. For details on the processing see the report: 2024-034_Processing_Report.doc. ---------------------------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
