The Allele Frequency Net Database is a freely available repository for immune gene frequencies in worldwide populations. Users can contribute allele, haplotype and genotype data and search existing records. HLA datasets are classified into Gold-Silver-Bronze standards, and a second version is in development.
CUGIR is a repository offering datasets and scanned maps. Datasets can be browsed by theme or found by zooming a map to an area and clicking a search button. Themes include boundaries, geology, agriculture, land cover, transportation, climate and elevation. The scanned maps section provides access to all map holdings.
The National Archive of Marine Seismic Surveys is a USGS data website presenting marine seismic reflection data within the United States. Visitors can click the map to select nearby surveys, mouse over survey names to highlight surveys, filter surveys by keyword and open individual survey pages for data and information.
The Cross-National Equivalent File is a household panel data package of equivalently defined variables for 9 general population household panel surveys. It harmonizes and makes available cross-national panel data for social science research, with country-specific data offered online through the CNEF-Investigator platform. Access requires an application.
The Environmental Data Initiative preserves and provides open access to environmental and ecological data, with information-rich metadata and a secure, persistent archive. It supports publishing and reusing data through tools, a REST API for workflow automation, and personalized data catalogs. Authentication for API access becomes required on July 30, 2026.
The General Social Survey is a survey project whose 2024 cross-section data is available with a multi-mode design. The data, collected between April and December 2024, include historically repeated measures and new data on digital societies, national identity and citizenship, and mental health stigma.
The Norwegian Meteorological Institute offers free access to much of its meteorological data and products through self-service download services. Customised delivery of data from other suppliers is also described, with charges for such arrangements.
