This record describes SVP Drifter deployments from the Marine National Facility RV Investigator Voyage IN2015_V03 and data access. This is the third research voyage for the RV Investigator departing Brisbane on the 3rd June and arriving in Sydney on the 18th June, 2015. The GDP (Global Drifter Program) SVP Drifters are Argos tracked Lagrangian Drifters designed to meet the need for accurate and global in-situ observation of Sea Surface Temperature (SST) and surface circulation. Each unit consists of a surface buoy and a subsurface drogue (sea anchor), attached by a long, thin tether. The buoy measures temperature and other properties, and has a transmitter to send the data to passing satellites. The drogue dominates the total area of the instrument and is centred at a depth of 15 meters beneath the sea surface. Manufacturer: Pacific Gyre Inc. A total of 10 drifters were deployed on this cruise, deployment information is provided in the documentation links below. Access to the data is via NOAA or system ARGOS.

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2015_V03 Titled: "Submesoscale processes – billows and eddies - along the productive shelf by the East Australian Current". The voyage took place between the 3rd to 18th June, 2015 departing Brisbane and arriving in Sydney. This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.

This record describes Hydrology (HYD) data collected from the Marine National Facility RV Investigator voyage IN2015_V03 titled Submesoscale processes - billows and eddies - along the productive shelf by the East Australian Current, departing Brisbane on the 3rd June and arriving in Sydney on the 18th June, 2015. 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 ammonia. CTD temperature and CTD salinity are also reported in this dataset. This dataset has been archived within the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the voyage report for this voyage and data processing report. Please see documentation and data links. Please note that quality flags for this dataset were modified on May 27, 2019 (see details in the Lineage section below).
