Macro-nutrients analysed were Silicate (SiO44- as Si), Phosphate (PO43- as P), Nitrate (NO3- as N) plus Nitrite (NO2- as N) referred to as NOx, Nitrite (NO2- as N) and Ammonium (NH4+ as N). Measurements were performed onboard RSV Nuyina in the Hydrochemistry containerised laboratory, the HydroBox. The HydroBox team measured DO, salinity and macro-nutrient samples from each CTD cast deployment where samples were collected. The team also measured macro-nutrients from underway samples (UWY), trace metal rosette (TMR) casts, pore water from kasten, multi-core sediments and Smith McGrab (CORE), and phytoplankton incubation (INC) experiments. In addition to that, the HydroBox team collected and measured salinity samples (TSG) from the underway system to calibrate the thermosalinograph.Sample ID for CTD and TMR samples are CTD or TMR number and Niskin position, e.g., for CTD 021 Niskin bottle 16 the sample ID is 02116; for the TMR 04 Niskin 07, the ID is tmr 0407.INC samples, CORE samples and UWY sample have their own logsheet.For sampling time and location, please see the elog document associated to the deployment. All results are csv files, supporting documents such as log sheets and data processing reports are pdf. Nutrient run analysis processing sheet (RAPS) are csv.Nutrient samples were analysed using segmented flow SEAL AA500 and results are in µmol/L. In-house methods SOP 001, SOP 002, SOP 003 and SOP 004 were used to analyse nutrients. Salinities were analysed using Guildline AutoSal 8400B and a Guildline PortaSal 8410A Salinometers and OSIL software. In-house method SOP 006 and SOP 008 was used to analyse salinity, units are Practical Salinity Unit (PSU).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 5.7 on the ship and re-processed on shore with HyPro 5.9.Progress Code: completedStatement: The data as of the end of the voyage was preliminary data only. All HydroBox data has since undergone final quality control checks, and all nutrient data has been corrected for Refractive Index. Nutrient data quality is good; Japanese KANSO certified reference materials for silicate, phosphate, nitrate and nitrite in seawater (RMNS CP) was included with each analysis run to determine accuracy. The salinometer was calibrated with IAPSO standard seawater P167 prior to each analysis run. The dissolved oxygen UV titrator was standardised each run with an inhouse standard.

Sample ID for CTD and TMR samples are CTD or TMR number and Niskin position, e.g., for CTD 021 Niskin bottle 16 the sample ID is 02116; for the TMR 04 Niskin 07, the ID is tmr 0407.
INC samples, CORE samples and UWY sample have their own logsheet.

For sampling time and location, please see the elog document associated to the deployment. All results are csv files, supporting documents such as log sheets and data processing reports are pdf. Nutrient run analysis processing sheet (RAPS) are csv.

Nutrient samples were analysed using segmented flow SEAL AA500 and results are in µmol/L. In-house methods SOP 001, SOP 002, SOP 003 and SOP 004 were used to analyse nutrients.

Salinities were analysed using Guildline AutoSal 8400B and a Guildline PortaSal 8410A Salinometers and OSIL software. In-house method SOP 006 and SOP 008 was used to analyse salinity, units are Practical Salinity Unit (PSU).

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 5.7 on the ship and re-processed on shore with HyPro 5.9.
