Water quality sampling sites. In lieu of a more complete metadata record this has been added in by F.McAllister (AIMS).

This dataset was developed from the written description of the boundaries contained in the Marine and Safety (Pilotage and Navigation) Regulations 2017. There are several commercial working ports within Tasmania. The limits of these ports often cover large areas, which include a full spectrum of on-water activities, including, recreational boating, charter operators, sailing races, as well as commercial shipping. Port waters are those defined by the Marine and Safety (Pilotage and Navigation) Regulations 2017. Rules are in place specific to all vessels operating within these defined port areas.

Water Quality Data from the AIMS Long Term Monitoring Program. Water and sediments (another dataset) were sampled at the same sites adjacent to all 52 reefs where fish and benthic transects are conducted. Sampling occurs in open water within 500 metres of the reef, on both sides (north and south flanks) of the reef. Sampled reefs occur throughout the Great Barrier Reef, and the reefs of the North West coast of Australia. To track change. Data recorded includes temperature, salinity, Secchi depth, suspended solids, silicates, ammonium, nitrite, dissolved nitrogen (organic, inorganic and total), dissolved phosphorus (organic, inorganic and total), chlorophyll-a and phaetophytin pigments. Observations commenced in August 1990 and ceased in 1996.

This file contains the water quality data summarized in the 1994 report entitled: Baseline Water Quality Inventory, Cape Hatteras National Seashore. The data and locations existed in the United States Environmental Protection Agency's Storage and Retrieval (STORET) water quality database management system when the report was published.

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. The "challenger" folder contains processed multibeam backscatter data of the South East Tasmania Shelf. The SIMRAD EM3002 multibeam backscatter data were processed using the CMST_GA MB Process, a multibeam processing toolbox codeveloped by Geoscience Australia and Curtin University of Technology This dataset is a contribution to the CERF Marine Biodiversity Hub.
