The research by scientists at the Woods Hole Oceanographic Institution is based on how much of the toxic red tide algae they found in its dormant state in the Gulf of Maine last fall. The dormant cysts act like seeds for the next years bloom.

The researchers then combine the cyst data with computer simulations of various conditions that affect the algaes growth Starbrite Tattoo Ink, such as winds and currents.

The prediction helps the shellfish industry and environmental managers better prepare for the annual bloom.
