Environmental Sciences Seminar:
What Are Eddy Fluxes? Biological and Chemical Feedbacks from (and to) the Ocean
Submesoscale and mesoscale eddies are ubiquitous and highly energetic rotating features of ocean circulation. Their influence on biological and biogeochemical processes stem not only from advective transport but also from the generation of variations in the environment, from the microscale to the mesoscale. A multidisciplinary approach involving sampling, remote sensing, and high-resolution modeling is woven through this presentation in an attempt to: 1) bridge long-standing scientific controversies on the signature of eddies on larval-fish distribution, 2) shed light on the transport and fate of underwater hydrocarbon plumes and surface UV filters, and 3) build a paradigm-shift in marine biophysics; quantifying the relationship of eddy activity at the length scale of biological community aggregations, where the collective behavior and motion of marine animal might also be relevant to the large scale driven motion of eddies.
