The Census of Agriculture is a complete count of U.S. farms and ranches and the people who operate them, taken once every five years. It examines land use and ownership, operator characteristics, production practices, income and expenditures. The National Agricultural Statistics Service provides access to agricultural data through the searchable Quick Stats database.

Cellosaurus is a knowledge resource and database that aims to describe cell lines used in biomedical research. Its scope includes immortalized, naturally immortal tissue limited-life distributed cell lines, and vertebrate cell lines with emphasis on human, mouse and rat, plus invertebrate and plant cell lines. Records include names, synonyms, accession numbers, species of origin and comments. It also offers search tools, downloads and documentation.
The Cell Image Library is an accessible resource database of images, videos, and animations of cells, capturing a wide diversity of organisms, cell types, and cellular processes. It offers advanced search, an open source API, and CDeep3M, and hosts over 12,000 unique datasets and 30 TB of data. It also accepts image submissions.
The Cell Centered Database is an archived UC San Diego Library digital collection of high resolution 2D, 3D and 4D data from light and electron microscopy of tissues from the nervous system and other systems. It provides raw data, reconstructions and segmented data for download, plus 2D images, animations and image maps for online visualization.

Find and access basic in biology and medicine research data, with indexed aggregated data.
Searchable repository for finding atmospheric, oceanography and climate datasets and measurement and test data.
CDAWeb is a service of NASA's Space Physics Data Facility that holds selected public non-solar heliophysics data from current and past missions and projects. It supports creating data subsets by date and variables, uniformly time binned data, plots in PDF, PS and PNG formats, and movies of image sequences. All SPDF services are unavailable during monthly system maintenance.
Research data portal for exploring economics records, including survey data.
CCHDO, the CLIVAR and Carbon Hydrographic Data Office, supports oceanographic research by providing access to global, vessel-based CTD and hydrographic data from GO-SHIP, WOCE, CLIVAR and other repeat hydrography programs. Data are openly accessible in standardized community formats, and search options include cruise, map and profile searches.
CCC Data Base is a database of convergent close-coupling cross-section data for atomic targets, created by Yuri Ralchenko and Igor Bray. It lists electron-impact data for several elements and ions, positron-impact data for several targets including H-like ions, and proton-impact data for helium. Molecular targets are directed to a separate site.
CATH is a free online database providing information on evolutionary relationships of protein domains, developed by the Orengo group at University College London. Structures from the Protein Data Bank are split into domains and classified by class, architecture, topology and homologous superfamily. Gene3D adds sequence data from UniProtKB and Ensembl, assigning domains to superfamilies.

CARS is the first data release of the Close AGN Reference Survey, a spatially resolved multi-wavelength survey of about 39 nearby luminous AGN and 2 starburst galaxies. It provides 3D cubes and high-level data products from optical IFU spectroscopy. All data is publicly available; registration offers a dedicated SQL workspace.
Dataset repository covering art history, music, theatre and media studies, with searchable text.
The Carbohydrate-Active enZYmes Database is a specialist database, online since 1998, describing families of structurally-related catalytic and carbohydrate-binding modules of enzymes that degrade, modify, or create glycosidic bonds. Data can be browsed by sequence-based families or by genome content, with new genomes added after GenBank releases. It also offers automatic annotation and human curation services for data.
The CANUE Data Portal is a product of the Canadian Urban Environmental Health Research Consortium for research on urban living and human health. The portal is described as a beta upgrade and offers a map browser, data request, data download and restricted area; users are asked to report issues to [email protected].
The CanPath Portal gives the research community resources to identify epidemiological and biological data available from six participating cohorts. An access request is initiated directly through the portal, which also covers the cohorts, datasets, biosamples and access policy.
