Maps from Environmental Studies

The following maps are a sampling of maps that are created by research performed through BOEM’s Environmental Studies Program. Search and view all of the studies reports in the Environmental Studies Program Information System (ESPIS).


Four-day trajectories of the different drifter groups released by the GLAD cruise including SPOT, flat surface drifters, NOAA, meteorological (MET) drifters and drifters released by the US Coast Guard. The S1, S2, T1, L1 and L2 clusters were released in a fractal configuration Figure 2.11 from OCS Study BOEM 2014-053: Implementation of Lagrangian Stochastic Models to Parameterize Submesoscale Transport for Tracking Oil Spills in the Gulf of Mexico
