The Marine Environmental Data and Information Network (MEDIN) is a partnership of UK organisations committed to improving access to UK marine data.

MEDIN is open to all with an interest in marine data and information. We are sponsored by a consortium of 15 sponsors and partnered with over 50 organisations. MEDIN Sponsors include a range of UK marine organisations who support MEDIN’s principles and lead the UK in marine data management. To officially join the network and become a MEDIN Sponsor, please email MEDIN stating your interest at enquiries@medin.org.uk. Our partners represent government departments and agencies, research organisations and private companies and have committed to practise good data management to help future-proof and secure UK’s valuable marine data. MEDIN reports to the Marine Science Coordination Committee.

The MEDIN portal contains information about 15,000 marine datasets.

The United Kingdom Directory of Marine Observing Systems (UKDMOS), is a unique internet-based searchable database of marine monitoring conducted by UK organisations.

Aiming to fulfil the basic requirement to know where, when and what is being monitored in the marine environment around the UK and provide information to help coordinate monitoring across different organisations, UKDMOS is a tool for searching monitoring programmes and series based on information such as the parameters measured or the frequency of measurements taken.

UKDMOS is managed and updated by the Marine Environmental Data and Information Network (MEDIN).
