The Mercury Passage marine habitat layer1: 25,000 depicts marine habitats from Marion Bay [147 57'-42 44'] to Lords Bluff [148 00'- -42 30'] from the coastline to the 40 metre depth contour including the complete coastline of Maria Island. 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 June 2001 to February 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 contour map 1:25000 depicts bathymetric contours from the coastlines of the islands of the Kent Group to the 3nm offshore limit. The contour intervals are at 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 bathymetric layer1: 25,000 depicts depth contours for the entire channel from the inside of the Breaksea Islands to Nixson Point [148d 00m, -42d 30m] to [148d 00m, -42d 30m]. The contour intervals are 5m, 10m, 20m, 30m, 40m, 50m. The data was collected through intensive field sampling from 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 southeastern Tasmania marine contour map 1:25000 depicts marine habitats from Marion Bay [147 57, -42 44] to Second Lookout Point [146 52, -43 40] from the coastline to the 40metre depth contour. The contour intervals are at 2metres, 5metres, 10metres, 20metres, 30metres and 40metres. 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.

Data layer containing 10 meter bathymetric contours for the Channel Islands National Marine Sanctuary and Santa Barbara Bay. Data are derived from 1:250,000-scale National Oceanic and Atmospheric Administration (NOAA) charts and Monterey Bay Aquarium Research Institute (MBARI), Santa Barbara Bay Multibeam Data

The Macquarie Harbour - 1:25,000 Series depicts bathymetric contours from Hells Gate [145d 13m, -42d 13m] to the mouth of the Gordon River [145d 31m, -42d 26m]. The contours are at 5 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995. It is not to be used for navigational purposes.
