Identifying Bloom Origins of the Toxic Dinoflagellate Karenia brevis in the Western Gulf of Mexico Using a Spatially Explicit Individual-Based Model

Harmful algal blooms caused by Karenia brevis result in large fish kills, human respiratory irritation, and shellfishing closures in affected areas. Most previous work on bloom formation in the Gulf of Mexico has focused on the west coast of Florida ...
