NEANIAS is an EU funded project, which aims to develop and integrate services to EOSC in the field of Underwater, Atmospheric and Space research. The objective of integration is to share these thematic services with scientific researchers of EOSC communities on these fields.

The European Open Science Cloud (EOSC) is a European Commission initiative aiming at a trusted, virtual, federated environment in Europe to store, share and re-use digital output from research (publications, data and software) across borders and scientific disciplines. The envisaged infrastructure is established by aggregating services, software, data and other types of scientific outputs from a diverse set of providers.

The EOSC initiative started in 2015, and the first phase of EOSC development finished under a multi-layered, interim governance structure that was active from November 2018 until the end of 2020. In the initial phase of development until the end of 2020, the Commission invested around €320 million to start prototyping the EOSC through project calls in Horizon 2020 - the Commission's research and innovation funding programme.

The EOSC Association is the legal entity established to govern the European Open Science Cloud. It was formed on 29th July 2020 with four founding members and has since grown to over 200 Members and Observers.

EOSC has a “core”, the set of services providing the means to discover, share, access and re-use data and services. The initial version of the EOSC core was developed and operated by the EOSC-hub project between 2018 and 2020. The EOSC Portal (https://eosc-portal.eu/) is part of the EOSC core, and during 2021 it was operated and further developed by the EOSC-Enhance project. Now, the developments of the EOSC core (and EOSC ecosystem in general) are being monitored by the EOSC Future project. The EOSC Portal provides a European delivery channel connecting the demand-side and the supply-side of the EOSC and all its stakeholders.

EU countries and countries associated with Horizon 2020, represented in the EOSC Governance Board, agreed unanimously to run the EOSC as a co-programmed European Partnership under Horizon Europe from 2021. Horizon Europe is the Commission's research and innovation funding programme, succeeding Horizon 2020 from 2021. The new governance model agreed with EU countries for the next EOSC implementation phase after 2020 will be tripartite including:

• The EU represented by the Commission

• The European research community represented by the EOSC Association

• EU countries and countries associated with Horizon Europe represented through a Steering Board to be set up in 2021 outside of the EOSC Association
