The Tasmanian Estuaries (Georges Bay) Bathymetry 1:25000 depicts bathymetric contours for Georges Bay, St Helens from the mean high water mark to the deepest part of the main basin at 25 m. The contour intervals are at 1 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Northern NRM region of Tasmania. It is not to be used for navigational purposes.

The north western Tasmania Bathymetry 1:25000 depicts bathymetric contours from Robbins Island [144deg 53min, -40deg 44min] to West Head [146deg 43min, -41deg 44min] from the coastline to 1500m from the coastline. The contour intervals are at 2 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Northern NRM region of Tasmania. It is not to be used for navigational purposes.

Bathymetric contours (5 m interval) for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore (whichever boundary is first identified). Detailed bathymetric contours were developed to be used to fulfill 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.

The River Tamar 1:25,000 depicts bathymetric contours from West Head [146d 43m, -41d 4m] to Launceston [147d 8m, -41d 27m] from the coastline to 1500m from the coastline. The contour intervals 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.

Geoscience Australia carried out marine surveys in southeast Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island. port_160 is an ArcINFO grid of the Port Arthur survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. This dataset is a contribution to the CERF Marine Biodiversity Hub.

Data represents marine bathymetry for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore (whichever boundary is first identified).

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.
