Long-term in situ marine observations largely vary in context. They could be performed in coastal areas or in the open sea, onto the seafloor or along the water column, and in addition, they could involve different types of systems (e.g. fixed or mobile platforms) and instruments. Their maintenance and development are operated by distinct teams and they primarily aim at serving local challenges and/or specific demands. But beyond this apparent diversity, common goals to ensure both sensor performance and data reliability are pursuedand the community, unequivocally, always get very good benefits in sharing and discussing their practices in the domain.

JERICO-RI, EMSO ERIC and AtlantOS, with the support of the European Commission, jointly organized the “Workshop on Interoperability Technologies and Best Practices in Environmental Monitoring” that took place in Brest, France, in October 2018. The workshop, addressed to technical and scientific staff, was designed to support the harmonization of practices for marine observations and favour technology interoperability.

The full agenda of the Workshop can be viewed here.

As part of it, EMSO ERIC specifically organized the last day session entitled “Dissolved oxygen: seafloor and water column data, from sensor to users”, which focused on the practical aspects of time series data production from sensors characteristics, acquisition parameters, quality control and calibration procedures, to data processing and interpretation. Broader objectives were also to promote best practices regarding the acquisition, qualification, and distribution of dissolved oxygen data, as well as to develop synergies around these data between EMSO, JERICO-RI and AtlantOS communities.

Here below are listed the presentations used as a support during the session:

  • Scientific issues and corresponding needs (spatial coverage, accuracy, data availability, etc..) associated with dissolved oxygen data for each community:
  • Data acquisition, state of the art of sensor knowledge, implementation, and recommendations:
