  • NESP Marine Biodiversity Hub Project C2 involved integration and analysis of three existing monitoring datasets: the Reef Life Survey (RLS), IMAS Long-term MPA (LTMPA), and AIMS Long-term (AIMS LTM) monitoring programs. These analyses involved generating new derived data on indicator values for survey sites in each of the datasets, which have been reported in the 2016 State of the Environment (SoE) report. Indicators included the biomass of large fishes, the community temperature index, the proportion of invasive species, crown-of-thorns seastar density and the proportion of threatened species. Details of calculation of these indicators and summary of trends in values across sites and times are provided in detail in a manuscript currently in the review process for an international journal [RSS to provide publication details once available], as well as in metadata supplied for the State of the Environment report. This metadata record provides links to each of the three datasets used in the synthesis, and links to access the derived biological indicator data reported in the 2016 SoE report. See "On-Line Resources" section.

  • The movement and behaviour of the Southern Rock Lobster (Jasus edwardsii) was monitored using a radio acoustic telemetry systems at two sites in eastern Tasmania.

  • Collected benthic community structure (species and abundance) and physical/chemical attributes (including sediment grain size, redox, sulphide and depth) for a large number of locations in the Huon and Derwent estuaries of south east Tasmania. Data was collected using van veen grab, divers where necessary or core samples. All locations include heavy metal data and site information. Most data was collected with spatial references (GPS).

    Temperature loggers have been deployed at a range of sites statewide in waters ranging between 6 and 22m depth. From 2012, 27 sites around Tasmania are being monitored. This record shows data collected from 2004 up to December 2020. Data is still being collected (June 2021) and will be added to this collection as it becomes available.

    Investigations of the impact of sewage and heavy metal inputs on inshore rocky reef communities have been limited to date because the scale of information on levels of pollutants has been much broader than the span of transects at sites investigated. As a consequence, analyses have been confounded by poor information on the variety of stressors operating at any site. Finer resolution data on pollutants are needed. To address this deficiency, the influence of sewage, heavy metals and other pollutants were assessed by collecting sediment samples at Reef Life Survey ecological monitoring sites and measuring a range of associated markers. This includes basic biogeochemical information (pH, turbidity, total phosphate, TKN, total organic carbon), stable isotopes (delta15N, delta13C), heavy metal concentrations, hydrocarbon concentrations.

    Marine benthic habitat data for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore. A full breakdown of habitat classifications is available on the SeaMap Tasmania website:

  • This data is primarily benthic invertebrate community information including species abundance & distribution collected by diver coring/grab. Spatial information is available for Huon Estuary and Tasman Peninsula (Nubeena) sites. Associated physical chemical parameters (sediment grain size, redox, sulphide, depth) were also collected and, in most cases, includes spatial GPS references.

    Seagrass meadows within the Broadwater were mapped using high-resolution 2005 orthorectified color aerial photography obtained from the Gold Coast City Council at a scale of 1:10,000 and pixel size 0.15 m. Using desktop GIS mapping (MapInfo Professional 8.0), polygons were drawn over all potential seagrass meadows at a scale of 1:5000. Spatial accuracy was estimated to be approximately ± 1 m on well-defined boundaries (e.g. dense seagrass meadows) and ± 2 m along poorly defined boundaries (e.g. sparse seagrass meadows).

    The seagrass dataset has been compiled by UNEP-WCMC in collaboration with Dr Frederick T. Short, University of New Hampshire, USA to show the global distribution of seagrass species. This dataset has been created from multiple sources and was used in the creation of the “World Atlas of Seagrasses”(2003). This polygon feature dataset is an update of the data used in the Atlas and is a unique data holding about the state of the world’s seagrasses. For a complete overview of global seagrass distribution this dataset should be displayed together with the associated point dataset. Both polygon and point datasets are available to download from this record.
