Air-sea Gas Flux Climatology; Progress and Future Prospects

24 September 2013

ESA is pleased to announce that the Air-sea Gas Flux Climatology; Progress and Future Prospects Workshop, will take place 24-27 September 2013 at IFREMER, Brest, France.

Information on the meeting can be found HERE.

Background to the Meeting

The air-sea transfer of gases is a major part of the budget of carbon dioxide and several other radiatively-important gases. While there are other methods for constraining global and basin budgets of the air-sea transfer, we depend on an air-sea gas flux equation for regional and sub-seasonal resolution of fluxes across the surface of the world's ocean.

That flux equation requires accurate values of transfer velocity, in addition to the concentrations of the dissolved gas in the upper ocean and in the lower atmosphere. This endeavour requires the maintenance of major observing systems (shipboard and satellite-borne) and deep understanding of transfer processes. It is a challenging task that will require interdisciplinary collaboration and cost-effective solutions.

The European Space Agency (ESA) and the International Surface Ocean Lower Atmosphere Study (SOLAS) community came together in 2010 to support a new initiative in this area and the OceanFlux GHG project arose. At the same time, there have been enormous efforts internationally on calculating climatologies, strengthening and organising the measurement of dissolved gases (e.g. SOCAT) and exploring new methods of measuring and modelling the transfer processes and exchange coefficients.

We invite interested parties to an international workshop in France in September 2013. The OceanFlux GHG project will be presented. Renowned international scientists will present overviews of key initiatives. We solicit oral and poster presentations from workshop participants. Together we will build a picture of the existing capability in air-sea gas flux climatology. More importantly, we will look ahead to new challenges and opportunities. ESA and other agencies are setting their own priorities and strategies. This workshop is an important opportunity to rationalize and explain the priorities of the scientific community.

Key aims will include
Identifying key challenges facing the air-sea gas flux community

Identifying opportunities and setting priorities

Practical information will be provided soon.
