On 8 March 2018, the European Ocean Observing System (EOOS) initiative held its first Forum. This brought together more than 80 ocean observing stakeholders from across Europe to discuss critical components of the European ocean observing system and ways to improve the existing coordination efforts. EOOS is a community initiative with a Steering Group co-Chaired by AtlantOS partners EuroGOOS and EMB. These organizations are working in collaboration with experts and advisers across the ocean observing value chain at national, regional and European scales. In 2018 EOOS is developing a Strategy and Implementation Plan 2018-2022 including concrete steps and community actions for the next five years. The recent Forum was a critical step to move this forward and an open stakeholder consultation will follow in Spring 2018. Following community feedback, the Strategy and Implementation Plan will be launched at the EOOS Conference on 21-23 November 2018 in Brussels. Conference registration is now open and it is free to attend.
