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.\nSample 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.\nINC samples, CORE samples and UWY sample have their own logsheet.\nFor 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.\nNutrient samples were analysed using segmented flow SEAL AA500 and results are in \u00b5mol/L.  In-house methods SOP 001, SOP 002, SOP 003 and SOP 004 were used to analyse nutrients.   \nSalinities 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).\nDissolved Oxygens were analysed using Scripps UV titrator and software, units measured in ml/L and converted to \u00b5mol/L.  Dissolved oxygen was analysed using in-house method SOP 005.\nAll data was processed with HyPro 5.7 on the ship and re-processed on shore with HyPro 5.9.", "num_resources": 4, "num_tags": 22,
