Euro-Argo main achievements

WP3

As part of WP3, Euro-Argo strengthened its links with other ocean observing networks, e.g. through the participation in the Ocean Gliders Best Practice developments. Euro-Argo was also involved in assessing the status of the European Ocean Observing networks status (D3.2 and D3.18) and the definition of the EuroSea strategic vision (D3.8).

Euro-Argo ERIC Office worked with Ifremer and CNRS, plus some volunteers from the Euro-Argo Management Board, to write a new Argo deployment strategy for the Deep-Argo and BGC-Argo missions (D3.16). This provides some new insight on how Euro-Argo plans to contribute to one fourth of the OneArgo array at the horizon 2030, including a rationale and some targets in terms of number of floats to be maintained in specific regions.

WP7

In the frame of the WP7, the project allowed Euro-Argo ERIC to deploy 5 BGC and 6 Deep Argo floats. They can be monitored on the following dashboard:

Specific studies were undertaken as part of WP7 based on the Argo data acquired thanks to these deployments (among other datasets), such as improvement of the procedures for the Delayed Mode Quality Control of pH measurements, and estimate of magnitude and drivers of regional carbon variability for the two deployments regions (Labrador Sea and tropical Atlantic).

WP8

The project supported the comic book ‘A journey with Ocean Observers’. This joint OceanOPS/Euro-Argo ERIC initiative aims to contribute to a greater understanding of ocean observations by readers aged 10 and over.
