Progress Code: completed Statement: Data source: original field data. See in2018_v01_HYD_Processing_Report document for method details. (1) 108 CTD stations were sampled with a 36 bottle rosette, mounted with only 24 NISKIN bottles (12L). (2) Nutrient samples were analysed using segmented flow SEAL AA3 and results are in µmol/L. In-house methods SOP 001, SOP 002, SOP 003 and SOP 004 were used to analyse nutrients. (3) Salinities were analysed using Guildline 8400B Autosal Lab Salinometer and OSIL software. The salinometer was calibrated with IAPSO standard seawater P161. In-house method SOP 006 was used to analyse salinity, units are Practical Salinity Unit (PSU). (4) Dissolved Oxygens were analysed using Scripps UV titrator and software, units measured in ml/L and converted to µmol/L. Dissolved oxygen was analysed using in-house method SOP 005. All data was processed with HyPro 5.3 on the ship and re-processed on shore with HyPro 5.5 and 5.6. Nutrient data decimal places within the CSV file; silicate is 1 decimal place, nitrite is 3 decimal places and NOx (nitrate + nitrite), phosphate and ammonium is 2 decimal places. Previously values below detection limit were set to zero these values are now displayed as the measured value even if that is a negative value. Oxygen Data is displayed to 3 decimal places. Salinity data is displayed to 4 decimal places, prior to in2018_t01 voyage it was 3 decimal places in the csv file. Data processing notes are in the process report (in2018_v01_HYD_ProcessReport_ver01.pdf). See hydrochemistry data processing report (and supporting documentation) for more information on each analysis and the corresponding data.
