A portal from the Government Digital Service contains daily marine heatwave and cold spell datasets from 2020 to the present. The data includes flags for events based on sea surface temperature percentiles and durations calculated over a 10-day rolling window. It is derived from the OSTIA L4 Reprocessed satellite data product.
From March to May 1992, the Australian Bureau of Mineral Resources and the Philippine Office of Energy Affairs conducted a joint marine survey in four offshore basins. The project collected 2,750 km of 192-channel seismic data, plus geochemical sniffer, gravity, magnetic, and bathymetric data across the NE Palawan Shelf, Cuyo Platform, Tayabas Bay, and Ragay Gulf. The data were acquired using the research vessel Rig Seismic and are intended for petroleum potential analysis.
Jervis Bay, Australia, is the location for a marine survey collecting paired geochemical and biological samples. The dataset includes data from 32 stations in a defined grid, with fine-scale replicates at 8 stations, and vertical CTD profiles for temperature and salinity. The survey was conducted by Geoscience Australia to investigate seasonal variation by combining results with a prior winter survey, with samples processed by late 2009.
Data from sediment cores collected by the Australian Geological Survey Organisation from the Exmouth Plateau, Perth Basin, and Ceduna Terrace. The dataset provides evidence of glacial-interglacial changes in surface ocean productivity and deep water chemistry since the Last Glacial Maximum, roughly 20,000 years ago. It includes measurements of sediment accumulation rates, biogenic components, and benthic foraminiferal stable isotopes.
Atmospheric backscattering coefficient profiles were collected by a NASA DC-8 aircraft from July 20 to August 8, 2017, over Alaska and parts of Canada. The data were measured by the CO2 Sounder Lidar instrument during the ASCENDS and ABoVE campaigns. Profiles include the atmospheric backscatter cross-section and two-way atmosphere transmission, provided in ICARTT format.
Five years of airborne campaigns from 2016 to 2019 collected atmospheric gas mole fractions for the NASA ACT-America project. The data includes carbon dioxide, methane, carbon monoxide, molecular hydrogen, nitrous oxide, sulfur hexafluoride, and other trace gases from discrete flask samples. Measurements were taken across all seasons and three regions of the central and eastern United States using two instrumented aircraft.
The Atmospheric Carbon and Transport - America project collected in situ measurements of carbon dioxide, methane, carbon monoxide, ozone, and ethane during flights over the central and eastern United States. NASA used two aircraft platforms, the Beechcraft B200 King Air and the C-130H Hercules, to gather continuous and flask sample data across various surfaces and atmospheric conditions. These merged products provide integrated measurements useful for modeling the transport and fluxes of atmospheric carbon dioxide and methane across North America.
Geoscience Australia Data published a study testing a model for stratiform copper deposit genesis in modern environments. The investigation focuses on the northeastern shore of Spencer Gulf, South Australia, where saline continental redbed groundwaters mobilize and transport metals to coastal Holocene carbonate complexes. The research supports the generation of metal-transporting groundwaters in semi-arid climates but notes challenges in forming zoned stratiform deposits.
Samples from eight dredge hauls collected during BMR cruise 107 from seamounts in the Vening Meinesz chain, south of Christmas Island. The data includes calcareous nannofossils, foraminiferids, and fragmentary macrofossils with ages ranging from the Late Cretaceous to the Holocene. The dataset is provided by Geoscience Australia Data and was last updated in April 2026.
Global anthropogenic carbon monoxide emissions are estimated from 2005 to 2021 using the Tropospheric Chemical Reanalysis v2 (TCR-2). TCR-2 uses JPL's MOMO-Chem data assimilation framework to simultaneously optimize concentrations and emissions from multiple satellite sensors. The data are provided as monthly grids at a spatial resolution of 1.125 x 1.125 degrees.
Four consecutive years (2020–2023) of field trial data evaluating six cocoa clones for yield stability and adaptability under varying environmental conditions in the humid tropics of India. The dataset, authored by Alwala Kireeti and shared under a CC-BY-4.0 license, likely contains measurements for dry bean yield, pod yield, bean number, and fat content. Analysis methods included combined regression, AMMI, and variance-based stability analyses to assess genotype-by-environment interactions.
1750 km of multichannel seismic data were collected on the west Tasmanian margin and 265 km off southeast Tasmania during a 1988 research cruise. The Bureau of Mineral Resources (BMR) conducted the cruise from March 24 to April 18, 1988, to examine basin structure and petroleum potential. Geological samples were taken at 49 stations, and thermal measurements were made at 10 stations to support seismic interpretation and sedimentation modeling.
Government of Yukon research provides instrument records and a hydromechanical model of subglacial processes beneath Trapridge Glacier, a surge-type glacier in the Yukon Territory. The study analyzes data from summer 1995, including high-pressure pulses and basal motion events, and compares four sediment flow laws in a coupled model.
Australian and surrounding marine seismic refraction surveys indicate substantial crustal mass variations. The dataset likely contains geophysical measurements used to infer sub-crustal mantle densities and compensation depths, published by Geoscience Australia Data. The record was last updated on 2026-04-20.
26 years of AVHRR Sea Surface Temperature data from 1992 to 2018 were used to map the East Australian Current off northern New South Wales. The dataset, sourced from the Australian Ocean Data Network, applies a Topographic Position Index technique to quantify the current's seasonal shoreward intrusion. It provides direct measurements of intrusion area and distance-to-coast, revealing a seasonal migration pattern.
A fleet of Australian ocean bottom seismographs (OBSs) recorded seismic data during commercial surveys in Australian waters. The instruments have a broadband frequency range and three-component recording capability, allowing analysis of both P-waves and S-waves. The dataset, presented at the 2017 APPEA Conference, demonstrates imaging of the crust and upper mantle from industry-standard airgun arrays.
Geoscience Australia's 2019 National Gravity Compilation project produced isostatic residual gravity anomaly grids for Australia. The grids were generated by Intrepid Geophysics using the Airy isostatic compensation method, incorporating new elevation models and both Airy-derived and seismic-derived Moho depth grids. The project aimed to create a benchmark isostatic residual grid and supplementary products, with results tested against Geoscience Australia's 2016 and 2019 models.
2012 to 2015 data provides high-resolution volumetric soil moisture profiles for the root zone at ten North American sites. The dataset contains Level 2/3 estimates derived from P-band synthetic aperture radar (SAR) measurements collected via NASA's AirMOSS instrument on a Gulfstream-III aircraft. It captures soil moisture at multiple depths with a 90-meter spatial resolution over areas approximately 100km by 25km per site.
A 2016 abstract presents geophysical data on the Lord Howe Rise, a submerged continental fragment formed during the Cretaceous period. The dataset, hosted by the Australian Ocean Data Network, includes marine and satellite geophysical data, dredge samples, and shallow drilling results. It aims to resolve the tectonic drivers behind the rifting of eastern Gondwana.
South Australia's Willunga Fault, ~40 km south of Adelaide, is the focus of a paleoseismic study. The dataset likely contains evidence for 3-5 ground-rupturing earthquakes since the Middle to Late Pleistocene, with single event displacements of 0.5–1.7 meters. This abstract was presented at the Australian & NZ Geomorphology Group Conference in September 2022.
