Full description

Australia has gazetted an ambitious national network of Commonwealth Marine Reserves that includes the iconic Huon and Tasman Fracture reserves off Tasmania where seamounts (‘undersea mountains’) support unique deep-water coral reefs. These reefs rank among the most bio-diverse globally.
Protection of deep-water coral reefs is a high-priority conservation concern nationally and internationally because deep-water corals are very fragile, easily impacted by human activities including bottom trawling, and are believed to recover very slowly. These corals may also be highly vulnerable to climate change because projected changes in water chemistry could limit the ability of corals to build calcareous skeletons.
Despite these concerns, and Australia’s significant investment in marine conservation, several fundamental ecological issues remain to be evaluated. These include defining the spatial extent of deep-sea coral communities inside and outside the Tasmanian reserves, and evaluating the resilience of the communities to bottom trawling. This information is important to understanding the dynamics of deep-sea communities globally, and for developing and implementing conservation management plans.
The survey aboard RV Investigator set out to determine the spatial extents of deep-sea coral communities in and adjacent to the Huon and Tasman Fracture reserves, and quantify changes in the communities by comparing samples taken in 2018 to samples taken, using similar methods, in 2007 and 1997. There was supplementary sampling on the heavily trawled St. Helens Seamount which was surveyed in 2008.

This metadata record refers to the image data collected during the survey.
The imagery collected for this project have been registered to the 2018 incidence of the CSIRO VARS database, where annotations have been added.
The annotations collected for this project have also been linked to the Oracle data base BHIMAGE and the associated videos and still images have been archived as described in MarLIN record 14436 'Benthic Habitats Video Image Archive'.
