Tasmanian Estuaries (Georges Bay) Marine Habitats - 1:25000

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.
