The Symposium periodically brings together the international scientific and engineering community investigating the mechanisms, parameterizations, and implications of gas transfer at water surfaces. The focus is on the physical and biogeochemical processes that govern gas flux, which include turbulence due to wind, wave breaking, and currents and the effect of natural and anthropogenic surfactants. These are the same mechanisms that govern the flux of heat and momentum and thus the conference is attended by many in the community studying a wide range of air- and water-side mixing processes that occur at or near the ocean surface. The exchange of greenhouse gases between the atmosphere and natural bodies of water is critical to characterizing and quantifying global climate change. Gas transfer at air-water interfaces encompasses a wide variety of research, including fundamental fluid dynamics, biogeochemistry, and oceanography. The establishment of a regular series of international symposia with a periodicity of about five years was motivated by the increasing societal interest in the consequences of gas transfer at air-water interfaces, the size and productivity of the research community, and the wide geographic distribution of active researchers. The Symposium has established a reputation as an important and influential venue for presenting and disseminating research progress to the community. The roughly 5-year period between gatherings ensures that significant progress since the last occurrence will be reported.
