37th International Liège Colloquium on Ocean Dynamics
Gas Transfer At Water Surfaces
The focus of the 37th Liège Colloquium on Ocean Dynamics is gas transfer at water surfaces with oral and poster presentations of recent advancements in this field. Discussions will identify the most critical conceptual and experimental improvements for future.
In the context of the present and future global climatic change, robust constraints of the exchange of greenhouse gases (CO2, CH4, N2O, DMS, CO, ...) between the atmosphere and aquatic ecosystems are needed. Gas transfer depends on the gas air-water gradient and the gas transfer velocity. The air-water gradient is generated by physical, chemical and biological processes acting from daily to climatic time-scales. The gas transfer velocity depends on numerous complex processes, the major one being turbulence in surface water and/or air. Wind stress at the interface is the main turbulence generator but at low wind speeds, the air-water gas transfer is further modulated by presence of surfactants, convective cooling, chemical enhancement and water currents. At high wind speeds, waves, bubbles and spray also strongly contribute to air-water gas transfer.
Topics of relevance to the Colloquium include:
History of the International Symposia on Gas Transfer At Water Surfaces
The First International Symposium
on Gas Transfer at Water Surfaces was held at Cornell University in Ithaca,
New York, 13-15 June, 1983. Dr. W. Brutsaert and Dr. G. H. Jirka were
organizers of this successful symposium that attracted approximately 150
participants. The second conference, the Second International Symposium
on Gas Transfer at Water Surfaces was held in Minneapolis, 11-14 September,
1990. It was organized by Dr. J. S Gulliver and Dr. J. P. Holland. The
third conference, aptly named the "Third International Symposium on Gas
Transfer at Water Surfaces", was held in Heidelberg, Germany 24-27 July,
1995. The organizing committee was comprised Drs. Jähne, Monahan, Munnich,
Asher, and Wanninkhof. The fourth conference was held in Miami in June
2000 with nearly 200 attendees. The conference committee led by Prof.
Mark Donelan and included Dr. Will Drennan, Dr. Eric Saltzman, and Dr.
The members of the Organizing Committee wish to express their gratitude to:
for their valuable assistance in organizing the Colloquium.
