The voyage took place from Hobart (TAS) to Brisbane (QLD) between April 6 and April 16, 2018. Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. Underway samples were also collected every 12 hours (or once every 24 if a CTD coincided with collection time) for nutrient analysis from the underway system which collects water from 7 m depth and is not filtered. This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report. {"type": "Polygon", "coordinates": [[[147.3, -43.3], [154.2, -43.3], [154.2, -31.3], [147.3, -31.3], [147.3, -43.3]]]} 147.3 154.2 -43.3 -31.3 Access to metadata links and voyage plans and summaries for all Investigator surveys. documentDigital HTML Access to Marine National Facility web page documentDigital HTML Download data from Data Trawler documentDigital HTML Download Deployments (csv) Dataset: in2018_t01_Hydro_Deployments_csv.zip documentDigital HTML Download Processing Report (PDF): in2018_t01_HYD_ProcessingReport.pdf documentDigital HTML Download Voyage Plan documentDigital HTML Download the netcdf data: in2018_t01_Hydro_nc.zip documentDigital HTML Download the csv underway data: in2018_t01_Hydro_Underway_csv.zip documentDigital HTML Unnamed resource documentDigital License Graphic PNG
