presented by Shane Ross (Virginia Tech), Banff International Research Station for Mathematical Innovation and Discovery, in September 2013. From a workshop on "Uncovering Transport Barriers in Geophysical Flows".
Techniques uncovering transport barriers and structures in environmental flows are poised to make a considerable impact on the field of ecology. Here we discuss some results relevant for real-time analysis and prediction of geophysical transport structures, which have arisen from applications to fluid-borne microbial ecology. Focusing on aeroecology, we consider challenges involved in forecasting atmospheric Lagrangian coherent structures, including the effect of subgrid turbulence and ensemble averaging. We also consider notions that may be relevant in an ecological context, such as persistent barriers, which may lead to the most diverse populations (in terms of origins) sampled sequentially at a geographically fixed location.
