Using Ozone to Remove Red Tide from Seawater

MOTE MARINE LABORATORY
A single-cell of the algae species Karenia brevis, which causes Florida red tide.

As coastal communities continue facing the repercussions from the nearly year-old red tide bloom lingering off the coast southwest Florida, researchers are searching for ways to reduce its impact, and possibly even physically remove the organism that causes it, Karenia brevis, from the water.

Mote Marine Laboratory in Sarasotais testing a device it first developed to purify water entering its Aquarium, called an Ozonator. It basically bubbles ozone through seawater inside a special container, destroying and removing organic matter it contains. We're joined by Dr. Richard Pierce, Associate Vice President for Research, and a Senior Scientist and Program Manager at Mote.
