    Two OneTemp HOBO pressure data loggers were installed at the Seaport Marina in central Launceston in June 2014 by Dr Ian Kidd, measuring water depth at 1-hr intervals as well as water temperature. Depth is calculated from temperature, total pressure, and barometric pressure, based on fresh water density. The height of the gauge relative to AHD was measured 23 March 2018 by Launceston City Council surveyor Leigh Cornwell, and a correction applied to the data to give water level in metres AHD. The gauge was installed for the purpose of Dr Kidd's PhD research into sediment transport processes in the upper Tamar, and remains open with data collected monthly by Karen Palmer (IMAS honours student). Both projects were supervised by Dr Andrew Fischer.

  • Time Series video to support Project C3 of the Marine Biodiversity Hub NESP programme 2015/2016. The video illustrates coastal change at the Southern end of Stradbroke Island QLD, using 118 Landsat observations from within the Australian Geoscience Data Cube (AGDC) from 1987-2016.

    The Marine Futures Project was designed to benchmark the current status of key Western Australian marine ecosystems, based on an improved understanding of the relationship between marine habitats, biodiversity and our use of these values. Approximately 1,500 km2 of seafloor were mapped using hydroacoustics (Reson 8101 Multibeam), and expected benthic habitats "ground-truthed" using towed video transects and baited remote underwater video systems. Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc. This project record provides linkage to each of metadata records describing data collected from the 9 study areas: Abrolhos Islands, Broke Inlet, Geographe Bay, Jurien Bay, Middle Island, Mount Gardner, Point Ann, Rottnest Island, and Southwest Capes​. To access the source datasets from each study site in their original (unaggregated) form, see child records linked to this parent record.

    The Tasman Fracture CMR AUV survey was a pilot study undertaken in 2014/15 as part of the National Marine Biodiversity Hub's National monitoring, evaluation and reporting theme. The aim of this theme is to develop a bluepint for the sustained monitoring of the South-east Commonwealth Marine Reserve Network. The particular aim of the survey was to contribute to an inventory of the distribution and abundance of demersal fishes in the reserve and adjacent reference sites using BRUVs. Data contained here represents footage collected using these drops and the associated scored data (abundance and lengths).

The Recherche Archipelago provides habitats for a diverse range of both terrestrial and marine species, and can be accessed either by vessel from the town of Esperance, or by four wheel drive along the coastal roads adjoining the Cape Arid National Park.

The area is host to a number of human uses, including recreational and commercial fishing, diving, surfing, recreational boat use and shipping and mining. The marine environment at this location is different to the other three study locations on the south coast, in that it encompasses the protected Two Peoples Bay with seagrass and invertebrate communities and the more exposed rocky and macroalgal reefs around the Mt Gardner peninsula itself.

  • This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project D1 - "Ecosystem understanding to support sustainable use, management and monitoring of marine assets in the North and North-west regions". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Effective management of marine assets requires an understanding of ecosystems and the processes that influence patterns of biodiversity. Focusing on the North and North-west regions, this project will leverage previous research to improve ecosystem understanding through a synthesis of existing information and by making testable predictions about the character and extent of conservation values, including for key ecological features (KEFs) and Commonwealth Marine Reserves. End-users and stakeholders will benefit from improved regional descriptions of marine ecosystems and uncertainty statements. In turn, this will inform prioritisation of future investments in monitoring marine ecosystems and State of the Environment reporting. Planned Outputs • A report on the synthesis (based on collations completed in 2015) of datasets and models for the North and NW identifying areas of greatest information coverage, gaps and themed to CMRs and KEFs in those regions. This report will also describe key spatial patterns in biodiversity (benthic and pelagic) and associations between benthic environments, fish and megafauna and large scale processes (e.g. oceanography). • Predictions and related products (maps) of the spatial distribution of biodiversity across the Oceanic Shoals CMR that encompasses benthic habitat, pelagic and demersal fish and megafauna communities. This will provide an example/test case at the National Prioritisation Workshop of how confidently predictive modelling can be used to describe assets and values in data poor areas to inform management and monitoring. • An updated conceptual model of ecosystem processes (benthic and pelagic) within the Oceanic Shoals CMR based on extension of modelling into pelagics. • A review of existing knowledge of the Ancient Coastline KEF. • A qualitative model of Glomar Shoal KEF (to be confirmed in consultation with DOE). • Communication products that capture activities and general interest stories of scientific results disseminated through NW Atlas social media links. • Upload of new relevant spatial data layers in NW Atlas for management and planning, and engagement with end users to maximize uptake of the NW Atlas products.

Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc. Surveys took place across 9 study areas, including Geographe Bay in the southwest Capes region. The marine environment at this location varies from extensive seagrass meadows in protected waters, to kelp-dominated granite and limestone reefs in areas of high wave energy. A small number of corals are also found throughout the region, reflecting the influence of the southward flow of the Leeuwin Current. The fish fauna is also diverse, with a high proportion of endemic species.

  • Coral community transect data collected concurrent with coral disease surveys in in the vicinity of Hoga Island in the Wakatobi Marine National Park, Sulawesi, Indonesia. Three replicate 20 m transects were collected by divers in each of reef flat, crest and slope habitats in 2005 (four sites, point intersect transect data), 2007, 2010 and 2011 (all six sites, line intersect transect data).

    Opportunistic visual surveys were conducted in transit to, and within, the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea during September and October 2012 onboard the RV Solander. This resource comprises species lists and estimated counts of marine mammals, sea snakes, seabirds, sea turtles and other large wildlife encountered during the voyage. The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters. Further information on the survey is available in the post-survey report published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L.,Siwabessy, J., Przeslawski, R., Picard, K., Alvarez de Glasby, B., Colquhoun, J., Letessier, T. & Heyward, A. 2013.
