The Euro-Argo European Research Infrastructure Consortium (ERIC) provides in situ ocean observations to a range of user communities, with an interest in the ocean’s state and its evolution. Euro-Argo ERIC aims at maintaining one quarter of the international Argo network, one of the most important components of the Global Ocean Observing System (GOOS).

Since 2014, the Euro-Argo ERIC Members joined their effort to get a better grasp of climate change, but also to support operational coeanography and to serve marine ecosystem health. This report summarizes the last five years main achievements and tells the story of the ERIC first steps.
