The mission of BioStudies is to provide access to all the data outputs of a life sciences study from a single place, by organising links to data in other databases at EMBL-EBI or elsewhere, as well as hosting data and metadata that do not fit anywhere else. The database accepts submissions via an online tool, or in a simple tab-delimited format. BioStudies provides rich mechanisms for defining and using metadata guidelines specific for a particular data source such as a project or a community, and organises datasets in collections.

A catalog of mouse genes expressed in early embryos, embryonic and adult stem cells was assembled. The cDNA libraries are freely distributed to the research community, providing a standard platform for expression studies using microarrays.

HydroShare is a system operated by The Consortium of Universities for the Advancement of Hydrologic Science Inc. (CUAHSI) that enables users to share and publish water-related data and models in a variety of flexible formats, and to make this information available in a citable, shareable and discoverable manner. HydroShare includes a repository for data and models, and tools (web apps) that can act on content in HydroShare providing users with a gateway to high performance computing and computing in the cloud. With HydroShare you can: share data and models with colleagues; manage access to shared content; share, access, visualize, and manipulate a broad set of hydrologic data types and models; publish data and models and obtain a citable digital object identifier (DOI); aggregate resources into collections; discover and access data and models published by others; use the web services application programming interface (API) to programmatically access resources; and use integrated web applications to visualize, analyze and run models with data in HydroShare.

The EMODnet geology portal provides free access to (i) geological data and metadata held by various geoscience organisations in Europe, delivered in accordance with international standards, and (ii) geological data products compiled at scales of 1:1,000,000, 1:250,000 and 1:100,000 or finer where the underlying data permit.

Rhea is a comprehensive and non-redundant resource of expert-curated chemical and transport reactions of biological interest. Rhea can be used for enzyme annotation, genome-scale metabolic modeling and omics-related analysis. Rhea describes enzyme-catalyzed reactions covering the IUBMB Enzyme Nomenclature list as well as additional reactions, including spontaneously occurring reactions. Rhea is built on ChEBI (Chemical Entities of Biological Interest) ontology of small molecules to describe its reaction participants. Since December 2018, Rhea is the standard for enzyme annotation in UniProt.

PubChem is the world's largest collection of freely accessible chemical information. Searches can be performed via a number of descriptors such as name, molecular formula and structure. Information is provided for chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more. PubChem is organized as three linked databases within the NCBI's Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool.

The Candidate Cancer Gene Database (CCGD) was developed to disseminate the results of transposon-based forward genetic screens in mice that identify candidate cancer genes. The purpose of the database is to allow cancer researchers to quickly determine whether or not a gene, or list of genes, has been identified as a potential cancer driver in a forward genetic screen in mice.

The Human Ageing Genomic Resources (HAGR) is a collection of databases and tools for the biology and genetics of ageing. HAGR features several databases with high-quality, manually-curated data: 1) GenAge, a database of genes associated with ageing in humans and model organisms; 2) AnAge, an extensive collection of longevity records and complementary traits for over 4,000 vertebrate species; and 3) GenDR, a database containing both gene mutations that interfere with dietary restriction-mediated lifespan extension and consistent gene expression changes induced by dietary restriction.

The NSIDC Distributed Active Archive Center (DAAC) processes, archives, documents, and distributes data from NASA's Earth Observing System (EOS) satellites, airborne campaigns, and field measurement programs. The NSIDC DAAC focuses on the cryosphere and related topics, including snow, sea ice, glaciers, ice sheets, frozen ground, soil moisture, and climate interactions. The NSIDC DAAC is one of the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) that archive and distribute earth science data, managed by NASA's Earth Science Data and Information System Project (ESDIS), as part of the Earth Science Data Systems (ESDS) Program.

Genome properties is an annotation system whereby functional attributes can be assigned to a genome, based on the presence of a defined set of protein signatures within that genome. This is a reimplementation at EMBL-EBI of a resource previously hosted at JCVI.
