Brief description
The Huon Commonwealth Marine Reserve (CMR) covers a broad depth range from the inner continental shelf at about 70 m, to abyssal depths of more than 3000 m. The majority of the area is in deep water. The Tasman Seamounts Marine Reserve that was proclaimed in 1999 has been wholly incorporated into the Huon Commonwealth marine reserve. The reserve contains a cluster of seamounts that appear as cone-shaped submerged mountains, which provide a range of depths for a diversity of plants and animals. The peaks of many of the reserve's seamounts are between 750 m and 1000 m below the sea surface and support endemic species, including large erect corals and sponges. Some of the flora and fauna are hundreds and possibly thousands of years old, making them some of the longest-lived animals on Earth. The reserve also provides an important connection between seamounts of the Indian Ocean and the Tasman Sea. This map of the geomorphology of the Huon CMR was prepared for the NESP Marine Biodiversity Hub Theme D (1) project: National data collation, synthesis and visualisation to support sustainable use, management and monitoring of marine assets.Lineage

Statement: The Huon bathymetric data sets have been sourced from CSIRO and Geoscience Australia. The data has been gridded to 50 m resolution.
The geomorphology layer is mapped to the Geoscience Australia Marine Geomorphology Classification Version 1.
Huon_Geomorphology_Level1_Provinces.shp: shapefile of the first level of the Geoscience Australia Seabed Geomorphology classification table to shelf, slope and rise.
Huon_Geomorphology_Level2.shp: defines the second level of the Geoscience Australia Seabed Geomorphology classification table to plane, slope and escarpment. This was generated by creating a slope layer and reclassifying the surface in ArcGIS to Plane (<2 degrees; Slope >2 degrees and Escarpment (>10 degrees) in slope.
Huon_Geomorphology_Level3_Finescale.shp: Fine scale geomorphic features identified from the bathymetric grid [Channel, Depression, Knoll, Ridge, Seamount]
Huon_Geomorphology_Level3_Broadscale.shp: Broad scale geomorphic features identified from the bathymetric grid [Floor plain, Rise, Shelf Plain, Terrace]
Huon_Seamap_Level1: Seafloor habitat classification as per the Seamap Australia benthic habitat classification table - Level 1: [Hard; Mixed or Soft Substrata]
Huon_AMP_Boundary.shp: Boundary layer from the Department of Environment detailing the spatial boundary of Huon AMP.
LEGEND FILES: Legend files for each of these layers are supplied in the file.
