The Seventh International Symposium on Gas Transfer at Water Surfaces was held May 18-21, 2015 in Seattle, Washington, USA. The Symposium has occurred every five years since 1983 to bring together the scientific and engineering community investigating the theory and applications of gas transfer at water surfaces. The focus is on the physicochemical and biogeochemical processes that govern gas fluxes, which include turbulence, bubbles, shear, and natural and anthropogenic surfactants. These are the same mechanisms that govern the fluxes of heat and momentum and thus the conference is attended by many in the community studying a wide range of transport processes that occur across gas-water boundaries or within the near-surface layers close to those boundaries.
Presentations from geosciences (oceanography, atmospheric sciences, hydrology) engineering disciplines (civil, mechanical, chemical, environmental) and the basic sciences related to all aspects of transport to, and transfer across, gas-water boundaries were presented. Symposium topics involving gas-water fluxes of mass, heat, and particulates include, but are not limited to:
- Laboratory and numerical studies
- Field observations
- Influence of wind, wave breaking, bubbles, and raindrops
- Biological effects, including surfactants
- Measurement techniques
- Remote sensing
- Global scale processes
- Ocean acidification
- High latitude processes
The meeting consisted of 4 days of oral and poster sessions, May 18-21, with a Welcome Reception on May 17. There were invited and keynote speakers to deliver overview talks on the broad themes of the Symposium. Poster sessions also took place, at which the presenters were stationed at their posters to take questions about their topics of research.
