CES "Dissolved oxygen"

Scientific Expertise Consortium Dissolved Oxygen

The Dissolved Oxygen Scientific Expertise Consortium (CES) was set up at the beginning of 2019 in order to network and federate scientific stakeholders at national and even international level around the theme of Deoxygenation of the offshore and coastal ocean and to establish an exhaustive and qualified database of national data on dissolved oxygen in the ocean. It is led by Véronique Garçon (LEGOS, CNRS), Joël Sudre (LEGOS, CNRS) and Sabine Schmidt (EPOC, CNRS), see their contacts in the tab below.

Oxygen is essential to the health of the planet. It affects the cycles of carbon, nitrogen and other key elements, and is a fundamental requirement for aquatic life. Nevertheless, deoxygenation is worsening in the coastal and open ocean (more information on dissolved oxygen).

In the long term, this synthetic product should include all Eulerian and Lagrangian observations, i.e. Winkler titration measurements, oxygen sensor data implanted on CTDs and on fixed anchorages/bottom observations/time series, oxygen sensors on BGC-ARGO profilers, on gliders and wavegliders or on any other type of autonomous vehicle/platform. One possible strategy would be to focus first on Eulerian data, then to work on Lagrangian data. The philosophy is to be inspired by the SOCAT approach, a community-based initiative developed and maintained by data providers and users.

July 2019 : Dissolved oxygen in the ocean: towards an ocean and coastal French community dataplatform

A first workshop is organized on Dissolved oxygen in the ocean: towards an ocean and coastal French community dataplatform at the joint initiative of LEFE/CYBER and ODATIS.

When: July 2 and 3, 2019

Where: in Paris (Jussieu, Pierre and Marie Curie campus of Sorbonne University), at the joint initiative of LEFE/CYBER and ODATIS.

Objective: Bring together ocean science stakeholders interested in dissolved oxygen and contribute to the development of an open access platform on dissolved oxygen concentration data collected by the entire French community, whatever the approach used: BGC-Argo, profiling float, anchorage, experimental data, water-sediment interface. The purpose is to identify existing data and develop specifications for the implementation of a synthetic data product, including quality control. It is part of the international effort led by the IOC-UNESCO GO2NE and IOCCP network.
