This three-year, $395,626 project grant from the National Science Foundation Division of Ocean Sciences aims to develop a physical-biological transport model of pelagic sargassum seaweed. Funded under the Geosciences program (CFDA 47.050), the grant supports basic research to expand understanding of the integrated Earth system through the atmospheric, earth, and ocean sciences. Specifically, the awardee LGL Ecological Research Associates, Inc. will build on Maxey-Riley frameworks for drift modeling to account for the combined effects of ocean currents, wind drag, and sargassum raft inertia as a function of growth and mortality responses to temperature and nutrients. Laboratory experiments and satellite tracking of deployed sargassum rafts will help validate transport modeling incorporating buoyancy-dependent drift and wave effects. Tools from ergodic nonlinear dynamics and transition path theory will quantify connectivity and uncertainty. The model aims to unravel constraints on sargassum pathways and variability, with implications for water quality and marine resources affected by pelagic blooms.
