The Mercury Passage marine habitat layer1: 25,000 depicts marine habitats from Cape Bougainville [148 00, -42 30] to Schouten Island [148 19, --42 20] from the coastline to the 40 metre depth. The habitat types depicted in the dataset include High profile reef, Medium profile reef, Low profile Reef, Patchy Reef, Sand, Hard Sand, Silty Sand, Silt, Seagrass, Patchy Seagrass, and Sparse Seagrass. The data was collected through intensive field sampling from November 2004 to December 2005 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.

The Mercury Passage contour map 1:25000 depicts bathymetric contours from Marion Bay [147 57' -42 44'] to Lords Bluff [148 15' -42 30'] from the coastline to the 40metre depth contour. The contour interval is 5 metres. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and is not to be used for navigational purposes

The Bathurst Channel marine habitat layer - 1: 25,000 depicts marine habitats for the entire channel from the inside of the Breaksea Islands to Nixson Point [145d 55m, -43d 18m] to [146d 08m, -43d 21m]. The habitat types depicted in the dataset include silt, silty sand, hard sand and low profile reef. The data was collected in October and November 2002 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995

The Kent Group marine habitat layer 1: 25,000 depicts marine habitats from the coastline to the 3nm limit of the island Deal, Erith, Dover and North East Islet. The habitat types depicted in the dataset include High profile reef, Medium profile reef, Low profile Reef, Patchy Reef, Sand, Hard Sand, Silty Sand, Seagrass, Patchy Seagrass, Dense and Sparse Sponge. The data was collected through intensive field sampling in September 2002 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.

The Macquarie Harbour marine habitat project 1:25000 depicts marine habitats from Hells Gate [145d13m, -42d 13m] to the mouth of the Gordon River [145d31m, -42d26m]. The habitat types depicted in the dataset include Reef, Cobble, Silt and Sand. The data was collected through intensive field sampling from January to June 2008 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.
