NSW Department of Climate Change, Energy, the Environment and Water developed this geospatial layer depicting the distribution of the Pink-tailed Legless Lizard (Aprasia parapulchella). The data is intended to inform impact and stewardship assessments under the Biodiversity Assessment Method. It was last updated on 2026-05-03 and is available under a CC-BY-4.0 license.
13.0 MB of data supporting a study on a phosphorus-modified NiFe2O4-TiO2 nanocomposite catalyst for the oxygen evolution reaction (OER). The dataset, authored by Siyabonga Patrick Mbokazi and last updated in April 2026, likely contains experimental results showing the catalyst achieved overpotentials of 294 and 321 mV at 10 and 50 mA cm–2 in 1 M NaOH.
Fish stocking records from Nova Scotia hatcheries detail the release of trout and salmon, including both fall and spring distributions. Columns suggest data on fish size, quantity, location, and stocking objectives for each event. This dataset appears on multiple government data platforms, indicating its official status and potential for longitudinal analysis.
A multibeam bathymetry and backscatter survey conducted from February 3 to 7, 2022. The data was acquired by Precision Hydrographic Service Pty Ltd onboard the Southern Ranger, using a Kongsberg 2040P MBES system. The objective was to map five areas south of Kangaroo Island for habitat mapping purposes.
A framework developed by Zhi Huang et al. estimates potential habitat condition for pelagic, epibenthic, and benthic infauna in all known submarine canyons along the Australian continental margin. The methodology uses geomorphic and oceanographic heterogeneity as surrogates to derive suitability scores. The framework is intended for spatial prioritization in marine planning and conservation.
The Petrel Sub-basin Marine Survey GA-0335 (SOL5463) was acquired by the RV Solander in May 2012 under the National Low Emission Coal Initiative (NLECI). It contains underwater video footage and 12-megapixel still images from 11 stations in shallow seabed environments to investigate CO2 storage potential. The survey was a collaboration between the Australian Institute of Marine Science (AIMS) and Geoscience Australia.
A 13.7 MB document by Maria A. Diaz-Mateus, last updated April 2026, details experimental results on microbial community structure, metabolic potential, and mineral formation during fish decay under controlled aerobic and anaerobic conditions. The study uses 16S rRNA gene sequencing, PICRUSt2 predictions, and SEM-EDS/XRD mineralogical analyses to compare decay trajectories. Results show distinct microbial assemblages and metabolic pathways linked to oxygen availability.
Data from controlled fish decay experiments comparing aerobic and anaerobic conditions, authored by Maria A. Diaz-Mateus and last updated in April 2026. The dataset includes measurements of oxygen, pH, hydrogen sulfide, water chemistry, microbial community composition via 16S rRNA sequencing, predicted metabolic functions, and mineral precipitate identification. The file is a 35.8 KB Excel spreadsheet.
A study in a tropical estuary compares phytoplankton and benthic microalgae responses to nutrient loads across tidal creeks with and without secondary treated sewage. The research highlights the scale and type of algal community response to sewage nutrients in situ, using sewage markers like coprostanol. The dataset is provided by Geoscience Australia Data and was last updated on 2026-04-30.
Geoscience Australia and Defence Science and Technology Organisation collected sediment samples from Sydney Harbour in August 2003. The analysis aims to groundtruth multibeam sonar mapping data and assess how sediment properties influence acoustic backscatter for benthic habitat classification. This work was part of the Coastal CRC's Coastal Water Habitat Mapping Project.
Spatial environmental data layers compiled from various sources for predicting distributional patterns of Antarctic seafloor biodiversity. The dataset is projected to a polar stereographic coordinate system (EPSG:3031) at a 2-kilometer resolution. It was published by the Australian Ocean Data Network and last updated on April 28, 2026.
Geoscience Australia Data provides a dataset on Ashmore Reef's sedimentological response to Holocene sea-level rise. The model is derived from a post-glacial sea-level curve, C14 dated facies changes, and growth phases extrapolated from a reference reef model. Data collection involved 12 vibro-cores across algal-foraminiferal sand and coral, with carbon dates ranging from 970 to 2020 BP.
A multidisciplinary dataset integrates observations from the manned submersible Nautile, ship-based sediment coring, and geophysical surveys at the Kazan mud volcano. The data focuses on biogeochemical processes like anaerobic oxidation of methane (AOM) and associated microbial and macrofaunal communities. The dataset was published by Geoscience Australia Data and was last updated on 2026-04-30.
A study evaluates hydrological and ecological changes downstream of a reservoir using eco-flow indicators and 32 Indicators of Hydrologic Alteration. The analysis, conducted by Mingqian Li of Jilin University, reveals significant seasonal flow alterations and reduced ecological diversity post-reservoir construction. Results indicate high-flow values and frequency decreased, especially in autumn, while low-flow components increased significantly in spring and summer.
A new seabed geomorphology classification system developed by Dr Rachel Nanson and an international team simplifies complex seabed interpretations into accessible maps. Geoscience Australia is implementing this internationally adopted method to map parts of Australia's Marine Park network. The maps support government decisions for the expanding Offshore Renewable Energy sector and sustainable ocean economy growth.
A methodology for quantifying uncertainties in marine habitat mapping based on physical surrogate data. The study uses a case study from northern Australia to define uncertainties from extrapolating bio-physical associations and interpolating physical data. It was published by the Australian Ocean Data Network and last updated on 2026-04-16.
Autonomous Underwater Vehicles integrated high-resolution imagery and multibeam bathymetry to map marine habitats in coastal and offshore waters of SE Tasmania. The study successfully surveyed kelp-dominated rocky reefs to deep mid-shelf sediments, identifying invasive species distributions. Presented at the OCEANS'10 IEEE Sydney Conference in May 2010, the data supports predictive modeling of biodiversity.
Brock Lake in the Northwest Territories was sampled during a winter subsistence fishery in November 2003 and assessed physically, chemically, and biologically in July 2004 and July 2005. The data includes physical, chemical, and biological variables and is documented in a Canadian manuscript report. It was published by Fisheries and Oceans Canada and is available under an open government license.
Rainbow Smelt habitat data from Fisheries and Oceans Canada's Fish Habitat Management Information System (FHAMIS). The dataset includes feeding areas, breeding areas, concentration, and species presence. Data was extracted from a literature review of documents produced between 1977 and 2001.
River, canal, and surface water transfer centerlines in England and Wales are classified for ecological and chemical status under the EU Water Framework Directive. The dataset, created by the UK Environment Agency, contains attribution from the 2022 classification results for Cycle 3 of the program. Geometry is simplified from the EA Detailed River Network for faster web mapping.
