Atmospheres, Oceans, Earths -- Unifying perspectives on geophysical and environmental multiphase flows

Coordinators: Elisabeth Guazzelli, Michael Manga, and Ray Shaw

Progress achieved via field observations, laboratory experiments, numerical simulations and theoretical approaches has led to significant advances in our understanding of geophysical and environmental fluid flows involving bubbles, drops and particles. This conference intends to bring together researchers whose primary expertise lies in the physics of particle- and droplet-laden flows in the geosciences to discuss common approaches to understanding the multi-scale and multi-physics nature of the multiphase geophysical flows across problems ranging from the dynamics of clouds to the transport of granular material over complex and erodible surfaces.

PLEASE NOTE: During the conference there will be an opportunity to present a poster. If you are interested in presenting a poster please visit the conference website and submit your title and abstract. Each poster board is 4 feet high x 6 feet wide. We ask that the posters be no larger than 44 inches high x 34 inches wide at the most (it is important to follow these measurements or posters may be turned down due to limited space) . There will not be a poster selection, all posters are welcome. The deadline to submit a poster is September 30.
