NOAA_NCEI's CLIVAR LADCP dataset contains estimates of deep ocean absolute currents and shear collected from 2003 to 2014. Measurements were obtained using Acoustic Doppler Current Profilers lowered on CTD rosette frames across multiple research cruises. The collection represents 20 years of evolving data acquisition and processing techniques for measuring full-depth water velocities.
A 1986 paper in the journal concluded that past activity attributed to the Cook submarine volcano was likely hydrothermal blowouts from a sea floor vent 1300 m below sea level. This discussion document is provided by the Australian Ocean Data Network and was last updated on 2026-04-10. The content likely contains geological analysis and debate regarding volcanic versus hydrothermal processes.
Surface underway measurements from the M/V Atlantic Cartier cover a 188-day period from December 29, 2016, to July 4, 2017, in the North Atlantic Ocean. The data include the partial pressure of carbon dioxide in both the atmosphere and surface water, alongside sea surface salinity, temperature, and barometric pressure. These measurements were collected using a CO2 gas analyzer as part of the Ship of Opportunity Program (SOOP/VOS) by researchers from Dalhousie University and GEOMAR.
From December 1994 to January 1996, the research vessel KNORR collected underway surface observations across the Indian Ocean and adjacent seas. The dataset includes measurements of barometric pressure, sea surface temperature, salinity, and the partial pressure of carbon dioxide in air and seawater. These data were collected as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program to study the ocean's role in climate.
Discrete sample and profile data were collected from the AURORA AUSTRALIS research vessel in the Indian and Southern Oceans (>60°S) between January 3 and March 17, 2003. The dataset includes measurements of dissolved oxygen, salinity, water temperature, potential temperature, hydrostatic pressure, and concentrations of nitrate+nitrite, phosphate, and silicate. These data support the CLIVAR program's goal of quantifying changes in ocean heat, freshwater, and carbon dioxide storage and transport.
NCEI Accession 0080987 contains surface underway measurements from the research vessel NATSUSHIMA across the Pacific Ocean from 1987 to 1991. The dataset includes simultaneous measurements of atmospheric and aquatic carbon dioxide fugacity, salinity, sea surface temperature, and wind conditions. Data were collected by researchers from Hokkaido University and the Meteorological Research Institute using specialized CO2 gas analyzers and equilibrators.
Surface underway data from the R/V Marcus G. Langseth spans the Arctic Ocean, Beaufort Sea, Bering Sea, Caribbean Sea, and multiple U.S. National Marine Sanctuaries from 2010-05-07 to 2013-06-25. The dataset includes measurements of the partial pressure (or fugacity) of carbon dioxide in water, salinity, and sea surface temperature. It was collected by researchers from Columbia University's Lamont-Doherty Earth Observatory and the University of Colorado using carbon dioxide gas analyzers and equilibrators.
Tropical Pacific oceanographic data from the equator at 156°E, collected between November 29 and December 26, 1992. The dataset contains 101 CTD casts measuring temperature, salinity, dissolved oxygen, and potential density at one-meter intervals from the surface to 1000 meters depth. It was gathered as part of the Tropical Ocean Global Atmosphere and Coupled Ocean-Atmosphere Response Experiment project.
A geospatial dataset aggregating the best available jurisdictional data on major hydrographic polygon elements, both natural and artificial, for Australia. The dataset is supplied by Jurisdictions and aggregated by Geoscience Australia, intended for defining hydrological features with attributes. It was last updated on 2026-04-10.
NCEI Accession 0144538 and 0148768 contain surface underway data collected from the RV Laurence M. Gould during 2004. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, and barometric pressure across the Caribbean Sea, North and South Pacific, South Atlantic, and Southern Oceans. Data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory, NOAA ESRL, and the University of Colorado using CO2 gas analyzers and equilibrators.
A reanalysis database provides hourly estimates of four plasma moments—density and temperature for hot protons and electrons—at geosynchronous orbit. The data covers the years 1990-2005 and fills gaps using an ensemble of models applied to measurements from Los Alamos sensors. Validation shows rank order correlations ranging from 0.65 to 0.97 for the reconstructed moments.
1991 to 1997 data contains estimates of deep ocean absolute currents and shear from Lowered Acoustic Doppler Current Profilers (LADCP) deployed during the World Ocean Circulation Experiment (WOCE). The dataset was collected by scientists inventing the field of LADCP acquisition and processing, requiring integration with ancillary data like CTD, GPS, and ship navigation. Its cross-platform presence on NASA EarthData and Data.gov signals its importance as a foundational resource for physical oceanography.
Via Scavi in Montegrotto Terme, Italy, is the location for this dataset of X-ray fluorescence (XRF) analyses on volcanic clasts extracted from mortar samples at the archaeological site. The dataset was authored by Simone Dilaria and last updated on April 13, 2026. It is a small, 12.6 KB file available in XLSX format under a CC-BY-4.0 license.
Geoscience Australia and the National Oceans Office collaborated on the AUSTREA marine survey to map the seafloor character over the southern Macquarie Ridge. Multibeam swath bathymetry, reflectivity, and high-resolution seismic data reveal complex morphology and sedimentation patterns. The data collection was part of the Australian Government South-east Regional Marine Plan.
Nimbus-6 Level 2 data from two Data Systems Tests in 1975 and 1976, assessing the impact of satellite observations on numerical weather forecasting. The product consists of meteorological parameters like relative humidity, temperature, and wind speed reported every 6 hours. NASA recovered the data from original magnetic tapes and now stores it online in its original proprietary binary format.
Nimbus-6 Level 3 data from two Data Systems Tests in 1975 and 1976, assessing the impact of satellite data on numerical weather forecasting. The product contains meteorological parameters like relative humidity, temperature, and wind speed on a regular latitude/longitude grid reported every 12 hours. NASA recovered this data from original magnetic tapes and stores it online in its original proprietary binary format.
HadGEM1 climate model simulations provide input for the IPCC Fourth Assessment Report, reflecting a future scenario of regionally-oriented economic development. The model includes interactive couplings for the atmosphere, ocean, biosphere, atmospheric chemistry, and aerosols. This specific run for the IPCC A2 Scenario was developed by the Hadley Centre between 2000 and 2004.
Projected global and regional emissions for five fluorinated gas groups (HFCs, PFCs, SF6, CFCs, HCFCs) are provided at 10-year intervals. The dataset contains scenario-based projections from 1990 through 2100, developed by the Intergovernmental Panel on Climate Change (IPCC). It is distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
HadGEM1 climate model simulations project future conditions under the IPCC A1B socioeconomic scenario. The Hadley Centre developed this model to provide input for the IPCC Fourth Assessment Report. The dataset contains a future scenario run continuing from a historic anthropogenic simulation.
Forty distinct global and regional greenhouse gas and sulfur emissions scenarios project future levels every decade from 1990 to 2100. The Intergovernmental Panel on Climate Change produced this foundational data set, which underpins major climate change assessments. Columbia University's CIESIN distributes the collection.
