Data

Your access to Sensors on Tropical Research Vessels data discovery and exploration is through the Australian Ocean Data Network (AODN) Portal.

The data streams from these instruments are provided on a real-time, near-real time or archival basis to ship users, researchers and government departments (e.g. BoM) requiring sea surface temperature, salinity, chlorophyll and turbidity data for the Australian tropics.  When operating, data records are transmitted to shore by satellite or phone links on a 3-hourly basis.

The reliable provision of near-real time data (nominal 3-hr intervals) is provided to the Bureau of Meteorology (BoM) for ongoing validation of Australian SST imagery.

Automated quality control is performed as data is received by AIMS, with post-hoc checking and quality control by project personnel.

R.V. Cape Ferguson

An example of the thermosalinograph during operation is displayed below, from the AIMS voyage tracker for Trip 6163 as part of the IMOS Southern GBR voyage to the Swains and Capricorn Bunkers. The R.V. Cape Ferguson departed Townsville on 19 Mar 2015 and returned 1 Apr 2015. The purpose of this trips was to service the IMOS Yongala NRS mooring; service the Abbott Point bottom frame; deploy WQ mooring at the mouth of the Burdekin; service IMOS Capricorn Channel mooring; service IMOS Heron South Mooring; service IMOS OTE Mooring; and service Loggers at Heron Island and One Tree Island.

R.V. Solander

From the AIMS voyage tracker for Trip 6045, the R.V. Solander departed Broome on 23 Aug 2014 and arrived in Darwin on 1 Sep 2014. The thermosalinograph was operating while the cruise was underway. This trip included the retrieval of IMOS PIL moorings, with CTD transect; retrieve a tide gauge at Scott Reef; recover some or all of Camden Sound moorings and redeploy two new moorings; retrieve Cape Londonderry mooring.
