This data is part of the 2013 report "Synthesis of seagrass mapping studies" conducted by the Water Science Branch of the Department of Water. Surveys were conducted by the WA Department of Water together with Geoscience Australia. The objective of these surveys was to collect baseline data on seagrass composition and distribution in key estuaries of southern and south-western WA. This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. The datasets making up the Irwin Inlet seagrass survey data are: WA_Irwin_SAV_polygons - polygon dataset showing interpolated percentage cover of Ruppia spp.

Aquatic flora surveys of the Hardy Inlet were conducted from the top of Molloy Island and the Scott River Basin to the mouth of the Inlet. Surveys were initially conducted in 2008 by Murdoch University’s Marine and Freshwater Research Laboratory (MAFRL) and forms part of the 2013 report "Synthesis of seagrass mapping studies" conducted by the Water Science Branch of the Department of Water. This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. Surveys were conducted again in 2018, 2020 & 2023 by the Department of Water and Environmental Regulation as "Hardy Inlet Seagrass Survey". The datasets making up the 2008 Hardy Inlet seagrass survey data are: WA_MAFRL_Hardy_seagrass_polygons - polygon dataset showing interpolated percentage cover of Ruppia spp. This record provides access to the initial MAFRL surveys. See associated DWER records in Data WA catalogue for access to newer surveys at this site.

Aquatic flora surveys were conducted in Wilson Inlet in 2007 and 2008. This data is part of the 2013 report "Synthesis of seagrass mapping studies" conducted by the Water Science Branch of the Department of Water. The 2007 survey was conducted to review any changes in seagrass distribution since the previous survey in 1996 (data not included in this record), and was funded internally by the Water Science branch. The 2008 survey was conducted by the WA Department of Water together with Geoscience Australia. The objective of the 2008 survey was to collect baseline data on seagrass composition and distribution in key estuaries of southern and south-western WA. This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. Surveys were conducted again in December 2017, April 2018, December 2019, December 2020, December 2021 and December 2022 by the Department of Water and Environmental Regulation as "Wilson Inlet Seagrass Survey". The datasets making up the 2007-2008 Wilson Inlet seagrass survey data are: WA_WilsonInlet_seagrass_polygons - polygon dataset showing interpolated percentage cover of seagrass with species information (where available). This record provides access to the initial WA DoW surveys. See associated DWER records in Data WA catalogue for access to newer surveys at this site.

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. freycinet_4m is an ArcGIS layer of the backscatter grid of the Freycinet Peninsula survey arae produced from the processed EM3002 backscatter data of the survey area using the CMST-GA MB Process This dataset is a contribution to the CERF Marine Biodiversity Hub.

This record describes a single aggregated dataset of the geomorphic habitat environment (facies) for Australia's 7 states and territories: New South Wales, Victoria, Tasmania, Queensland, Northern Territory, South Australia, Western Australia. The classification system contains 12 easily identifiable and representative environments: Barrier/back-barrier, Bedrock, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. For the New South Wales region, 134 coastal waterways are described. Most of the estuaries of New South Wales are under intense land use pressure with approximately 80% of the State's population living near an estuary (NSW Dept of Land and Water Conservation) For the Victorian region, 54 coastal waterways are described. Most of the 54 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition. For the Tasmanian region, 88 coastal waterways are described. The majority of near pristine estuaries in Tasmania are located in the south and west of the State and on Cape Barren Island, according to the Department of Primary Industries, Water and Environment. For the Queensland region, 213 coastal waterways are described. Southern and central Great Barrier Reef lagoon coasts have a broad spectrum of river, tide and wave- dominated estuaries. For the Northern Territory region, 63 coastal waterways are described. Estuaries on the northern Arnhem Land, Gulf of Carpentaria coasts are predominantly tide-dominated estuaries, which vary greatly in size and floodplain characteristics. For the South Australia region, 36 coastal waterways are described. Most of the 36 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition. For the Western Australia region, 103 coastal waterways are described. Western Australia has a diverse range of Estuaries due to different climates. Ranging from mostly "near pristine" and tide influenced estuaries in the north to "near pristine" wave dominated estuaries in the southwest region.
