    Multibeam echosounder data collected on Southern Surveyor voyage 01/2008 using the Simrad EM300 multibeam echosounder to acquire high resolution seafloor bathymetry and backscatter information. This voyage took place off southern Tasmania during January 2008. Ping rate varied according to depth. Data are stored in Simrad *.all raw format at CMAR and Geoscience Australia (GA). There are 392 files totalling 4.69 GB of raw data in this dataset. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report (as available).

  • This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 01/2008. The voyage took place in the Southern Ocean, below Tasmania, from 11 January to 1 February 2008. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset may be contained in the voyage plan and voyage summary (as available). The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data are recorded at 10 second intervals.

    The collaborative voyage, on RV Thomas G Thompson, including US and Australian researchers was led by chief scientists Dr Jess Adkins from the California Institute of Technology and Dr Ron Thresher from CSIRO's Climate Adaptation and Wealth from Oceans Flagships. This voyage follows up on work done on RV Southern Surveyor during SS 01/2008. The survey deployed the ROV Jason in the Huon and Tasman Fracture Commonwealth Marine Reserve, south-west of Tasmania, It also sampled areas of the Cascade Seamount and seamounts off the coast at St Helens (Tas). The focus of the survey was collection of fossil corals (Desmophyllum sp.), description of habitats at depth between 700 and 4000 m depth and establishing two long-term monitoring sites in the Huon CMR (settlement plates). It explored and sampled on the near vertical slice in the earth's crust, known as the Tasman Fracture Zone, which drops from approximately 2000 metres to over 4000 metres. Jason was used to collect video, high definition still images (mosaiced images) and selective samples of fossil corals and invertebrate fauna.
