The Tasmanian Estuaries (North West) Marine Habitats 1:25,000 layer depicts marine habitats of four estuaries (Montagu River, Duck Bay, Black River and Detention River). The habitat types depicted in the dataset include rocky reef, sand, hard sand and seagrass. The data was collected in April 2005 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The shallow waters of the estuaries enabled the use of aerial photography imagery as the primary data source. The habitats defined in the imagery required thorough checking in the field via underwater camera equipment, echo sounder data, and a Differential GPS unit to enable field checking of the image interpretation. 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 Cradle Coast NRM region of Tasmania.

The north western Tasmania marine habitat project 1:25000 depicts marine habitats from Robbins Island [144deg 53min, -40deg 44min] to West Head [146deg 43min, -41deg 44min] from the coastline to 1500m from the coastline. The habitat types depicted in the dataset include Reef, Sand, Seagrass, and Cobble. The data was collected through intensive field sampling from February to September 2006 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 data was collected through intensive field sampling from June to December 2000 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 Tasmanian Estuaries (South East) Marine Habitats 1:25,000 layer depicts marine habitats of nine estuaries (Bryans lagoon, Catamaran River, Cloudy Bay Lagoon, D'Entrecasteaux River, Great Swanport, Little Swanport, Pipeclay Lagoon, Pitt Water and Southport Lagoon) in the south east of Tasmania. The habitat types depicted in the dataset include rocky reef, sand, hard sand and seagrass. The data was collected from November 2004 to September 2005 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The shallow waters of the estuaries enabled the use of aerial photography, including purpose flown aerial surveys, and satellite imagery as the primary data source. The habitats defined in the imagery were ground truthed in the field with underwater camera equipment, echo sounder data, and a Differential GPS unit. The dataset is intended for the use of fulfilling the coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Southern NRM region of Tasmania.

The Tasmanian Estuaries (Georges Bay) Marine Habitats 1:25,000 layer depicts marine habitats of one estuary (Georges Bay) near St Helens. The habitat types depicted in the dataset include rocky reef, sand, hard sand and seagrass. The data was collected from November 2004 to March 2005 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The shallow waters of the estuaries enabled the use of aerial photography and satellite imagery as one of the primary data sources, with habitats below the depth range that imagery could detect determined with underwater camera equipment, echo sounder data, and a Differential GPS unit, This equipment was also used to field check the habitats determined from image interpretation. 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.

The Tasmanian Estuaries (South East) Marine Habitats 1:25,000 layer depicts marine habitats of nine estuaries (Bryans lagoon, Catamaran River, Cloudy Bay Lagoon, D'Entrecasteaux River, Great Swanport, Little Swanport, Pipeclay Lagoon, Pitt Water and Southport Lagoon) in the south east of Tasmania.

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.

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.

Rock Platforms on Tasmania's east coast, Flinders Island, and the north coast as far west as Port Sorell, were surveyed between December 1995 and September 1996. At each of 51 sites two transects were sampled using quadrats. All animals and plants were counted, or in the case of sessile species, their cover was estimated.

The data is quantitative abundance of fish, megafaunal invertebrates and percent algal cover derived from underwater visual census methods involving transect counts at rocky reef sites around Tasmania. This dataset allows examination of changes in Tasmanian shallow reef faunal and floral communities over a decadal scale, with initial surveys conducted in 1992-1995, and again in 2006-2007. There are plans for ongoing surveys. An additional component was added in the latter study - a boat ramp study looking at the proximity of boat ramps and their effects of fishing. We analysed underwater visual census data on fishes and macroinvertebrates (abalone and rock lobsters) at 133 shallow rocky reef sites around Tasmania that ranged from 0.6 - 131 km from the nearest boat ramp. These sites were not all the same as those used for the comparison of 1994 and 2006 reef communities. The subset of 133 sites examined in this component consisted of only those sites that were characterized by the two major algal (kelp) types (laminarian or fucoid dominated). Sites with atypical algal assemblages were omitted from the 196 sites surveyed in 2006. This study aimed to examine reef community data for changes at the community level, changes in species richness and introduced species populations, and changes that may have resulted from ocean warming and fishing. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. The underwater visual census (UVC) methodology used to survey rocky reef communities was designed to maximise detection of (i) changes in population numbers and size-structure (ii) cascading ecosystem effects associated with disturbances such as fishing, (iii) long term change and variability in reef assemblages.
