Harmful Algal Blooms

Harmful algal blooms (HABS) are increasing in frequency and magnitude in coastal waters. HPL scientists are involved in investigation of the causes and consequences of HAB events in Chesapeake Bay and around the world.

Current Research:

The interdisciplinary project “Grazing and Windows of Opportunity for Dinoflagellate Blooms” is investigating the effects of microzooplankton and mesozooplankton grazing on the formation and persistence of dinoflagellate blooms in the two tributaries of the Chesapeake Bay. It is hypothesized that blooms can only occur when “windows of low grazing pressure” coincide with environmental conditions suitable for dinoflagellate growth.
