A geological dataset from the Australian Ocean Data Network details growth fabrics and rates of Holocene reefs in the Great Barrier Reef. It is based on analysis of 61 drill holes into 24 reefs, providing nearly 250 radiocarbon dates. The data delineates five major biosedimentologic facies and quantifies their depositional rates.
A map from 26 May 2022 shows satellite-detected surface waters in Sylhet, Mymensingh, Dhaka, and Chattogram Divisions, Bangladesh. It was produced by the United Nations Satellite Centre (UNOSAT) using Sentinel-1 radar imagery and an automated machine learning analysis. The analysis estimates about 6,800 km² of land was flooded, affecting approximately 5,400 km² of cropland and 1,270 km² of herbaceous wetland.
Northern Queensland and eastern Northern Territory, including the Gulf of Carpentaria, are covered by this geological synthesis. The bulletin summarizes field surveys that began in 1969 by the Bureau of Mineral Resources and the Geological Survey of Queensland, incorporating geological mapping, geophysical surveys, and stratigraphic drilling. It is based on aerial photography, Landsat imagery, and wire-line logging of water bores.
Visean-age fossil samples from the Delepinea aspinosa Zone in New South Wales were analyzed using multivariate cluster analysis to identify recurrent species associations. The dataset likely contains results from the Inflatia elegans and Linoprotonia tenuirugosa Subzones, showing several intergrading communities. It was aggregated by the Australian Ocean Data Network and last updated on 2026-06 27.
Biogeochemical-Argo float data reveals a two-regime model reduces estimates of particulate organic carbon flux into the mesopelagic zone by 40-60%. The dataset, hosted by the Australian Ocean Data Network, supports improved modeling of the ocean's biological carbon pump. Findings suggest a need for more mechanistic representations to reduce uncertainties in ocean-climate feedbacks.
Replication data from a paper by Carl Henrik Knutsen of the University of Oslo analyzing global democratic trends. The paper investigates evidence for democratic decline over the last decade, evaluates measurement methodologies, and examines potential biases in expert coder assessments. It specifically critiques V-Dem's methodology and Little and Meng's proposed objective democracy measures.
Digital Rocks Super Resolution Dataset 1 contains organized 2D slices and 3D volumes of Bentheimer Sandstone and Estaillades Carbonate micro-CT images for machine learning. The dataset includes 800 images for training, 100 for validation, and 100 for testing, with high-resolution, 2x, and 4x downsampled versions. It was created by Ying Da Wang of UNSW Sydney and is structured similarly to the DIV2K benchmark dataset.
A collection of over 15,000 prompts used for OpenAI's GPT Image 2 model, paired with the resulting generated images. The dataset, created by Goku-OpenLab, exceeds 5GB in size and includes full metadata and preview images. It was last updated on Hugging Face in July 2026.
A list of most Senior Civil Service posts in the UK Department for Education. The data includes job titles, contact details, line manager information, and officer names where disclosed. The dataset is published by the Department for Education under the OGL-UK-3.0 license and was last updated on 2026-07-15.
The eastern sector of the Southern Ocean between 55°E and 80°E is covered by this dataset on Antarctic krill (Euphausia superba). Data was collected during the RV Investigator voyage IN2021_V01 from 29 January to 24 March 2021 under the TEMPO program. It provides estimates of krill areal biomass density derived from acoustic data and biological sampling.
19% omission and 41% commission error rates characterize this Landsat-derived burned area dataset validated with high-resolution commercial satellite imagery. The United States Geological Survey algorithm identifies burned areas from 1984 through 2018 using machine learning and image segmentation on Landsat analysis ready data. This product provides a unique data source for monitoring spatial and temporal fire patterns across the contiguous United States.
Western Europe weather data for detecting bow echoes using convolutional neural networks. The dataset contains 9,174 simulated reflectivity fields and manually labeled ground truth contours from Météo-France's AROME-EPS and AROME models. It was created by Arnaud Mounier of the Centre National de la Recherche Scientifique for training and validating a U-Net model.
Raster data for the 2023 Parliamentary Constituency of Lagan Valley. The boundaries are official, as agreed by The Boundary Commission of Northern Ireland. The dataset was last updated on 2026-07-08 and is provided by OpenDataNI under the OGL-UK-3.0 license.
Two sediment cores collected from beneath the Amery Ice Shelf in East Antarctica describe physical sedimentation patterns. The cores, AM01b and AM02, comprise Holocene siliceous muddy ooze and provide indicators like lithology, 14C surface ages, absolute diatom abundance, and diatom assemblages. This dataset was published by the Australian Ocean Data Network and was last updated on June 23, 2026.
ETAS (Eastern TASmania) model output provides high-resolution three-dimensional estimates of daily ocean currents for eastern Tasmania. The dataset consists of eastward (u) and northward (v) currents organized into yearly files covering the period from 1993 to 2014. It is provided by the Australian Ocean Data Network.
Eastern Tasmania ocean model output provides three-dimensional daily estimates of temperature, salinity, and circulation from 1993 to 2014. The data includes temperature, salinity, density, sea level, and eastward and northward currents organized into timeseries files. It is hosted by the Australian Ocean Data Network.
1700 km of 24-channel seismic data and 2550 km of bathymetric, gravity, and magnetic data were recorded during a 1977 R.V. Valdivia survey between the Scott Plateau and Java Trench. The dataset includes 31 bottom samples from water depths between 2000 m and 5800 m, providing information on sediment layers and tectonic structures. It was aggregated by the Australian Ocean Data Network.
Dampier Peninsula in Western Australia contains marine fossils from the Upper Jurassic (Kimmeridgian and Tithonian) and Lower Cretaceous (Neocomian and Aptian) periods. The data is documented in publications by authors including Brunnschweiler, Guppy, and Fairbridge, with stratigraphic context provided by McWhae et al. (1958). Some fossil specimens were lost in a 1953 fire, and descriptions rely on surviving photographs.
Marine National Facility RV Investigator voyage IN2020_V08 collected oceanographic and biogeochemical observations across the subpolar and polar Southern Ocean between 4 December 2020 and 15 January 2021. The dataset includes measurements of temperature, salinity, chlorophyll fluorescence, nutrients, particulate organic carbon, and dissolved iron. It was compiled to investigate the structure and environmental controls of deep chlorophyll maxima and phytoplankton productivity in the Southern Ocean.
A new stratigraphic interpretation of Cretaceous sedimentary rocks from petroleum wells, stratigraphic holes, and water bores along the southern Australian coast. The record, presented by the Australian Ocean Data Network, correlates onshore and offshore sections using biostratigraphic and seismic data. The succession reaches a maximum thickness of more than 357 meters in the Madura 1 well, documenting depositional environment evolution from the Valanginian to Campanian stages.
