The International Council for the Exploration of the Sea (ICES) is an intergovernmental marine science organization, meeting societal needs for impartial evidence on the state and sustainable use of our seas and oceans. The goal is to advance and share scientific understanding of marine ecosystems and the services they provide and to use this knowledge to generate state-of-the-art advice for meeting conservation, management, and sustainability goals. The ICES Data Centre accepts a wide variety of marine data and meta-data types into its databases. The data formats, guidelines and vocabularies are specific to the type of data and whether it is associated with a marine convention monitoring programme.
