Brief description
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.Lineage
Progress Code: onGoing
Maintenance and Update Frequency: asNeeded
Statement: Data source: field surveys
Imagery: selected images collected during the ROV dives were annotated for faunal abundance; the annotation data is held at CSIRO marine laboratories.
Invertebrate Fauna: species occurrence data from physical collections using the ROV Jason were updated with identifications received from taxonomic experts. The data including all upgrades entered until Dec 2016 have been transferred to the CSIRO Information and Data Centre.
