The EuroMarine Consortium is comprised of European academic or research organisations that are active in marine sciences. It was launched on 1 June 2014, when sixty-six organisations signed the EuroMarine consortium agreement. Since 2015, new member organisations can join by signing a Consortium Accession Document. Full Members contribute to the budget and have voting rights. Organisations outside Europe can join as Invited Members.
The EuroMarine Association, created in 2018 and made operational in 2019, provides the network with both an efficient and flexible management structure and a legal status as a not-for-profit organisation under French law. Since 2019, the Association has managed the budget and daily activities of the Consortium (a role formerly fulfilled by IRD as the EuroMarine Coordinator).
