The Sargassum Ocean Sequestration (SOS) pilot experiment occurs in the Caribbean Sea from May 26 to June 9, 2019. It is led by Prof. Alex Slocum and Mr. Luke Grey of the Precision Engineering Research Group in Mechanical Engineering at MIT. The MSEAS team specific objectives are to: (i) Utilize our new Lagrangian transport theory and methods to forecast transport of sargassum in the Caribbean Sea between the Yucatán Peninsula and Cozumel; (ii) Apply and expand our multi-resolution submesoscale-to-regional-scale ocean modeling for real-time forecasting; (iii) Help design field experiments and predict sargassum collection strategies in the region. We thank all of the SOS team members for their inputs and collaboration. We also thank NCEP for their atmospheric forcing data.
The research of the Precision Engineering Research Group is sponsored by the Federal Government of Mexico.
Real-time MSEAS Forecasting
- MSEAS Deterministic Ocean Forecasts
Real-Time Estimates of Present (26 May 0000Z) Environmental Conditions (downscaled from HYCOM) Full Modeling Domain (200m resolution) Interactive Ocean Physics Forecast Sargassum Flow Map Forecast 0m Temperature 2m Vorticity 
MSEAS high-resolution tidally-forced forecasts downscaled from HYCOM - Methods and Systems: The MIT-MSEAS Primitive-Equation (PE) ocean modeling system is utilized in real-time to provide ocean forecasts for Lagrangian transport and analyses in the region. The modeling system was set-up with 200m resolution in the Caribbean Sea/Gulf of Mexico domain. The ocean forecasts are initialized from HYCOM, downscaled to higher resolution and updated with ocean data from varied open sources of opportunity. These ocean simulations are forced by atmospheric flux fields from the 12-km North American Model (NAM) from the National Centers for Environmental Prediction (NCEP) and by tidal forcing from TPXO8, but adapted to the high-resolution bathymetry and coastlines.
