Dispersants: The Lesser of Two Evils

During the Deepwater Horizon spill, dispersants were sprayed onto oil slicks on the surface of the water, as well as directly into the escaping oil, to break up as much as possible. Ever since, scientists have been studying the impacts of these dispersants.

They’re now evenly split on whether their use was ultimately a good or bad choice for the environment. For some organisms, dispersant plus oil is a very toxic mix. For others, the dispersant itself was actually more toxic than the oil alone. And, for yet other another set of organisms, the dispersant helped, as oil posed the most serious threat.

PODCAST OF THE WEEK
GulfCast: The Science of Dispersants

Dr. Noshir Pesika (Tulane University) and Dr. Claire Paris-Limouzy (University of Miami) are working to understand the effects of dispersants sprayed during the Deepwater Horizon disaster. Dispersants are chemicals meant to help the cleanup effort by breaking oil apart into smaller droplets and keeping it from sticking to other surfaces.

Gulf’s deep-sea coral granted new protections by federal regulators

Federal fisheries regulators have approved a plan granting new protections to some of the Gulf of Mexico’s oldest and most fragile stands of deep-sea coral.

The Gulf of Mexico Fishery Management Council unanimously voted to designate about 480 square miles as Habitat Areas of Particular Concern, a status that would make them a priority for conservation and scientific study. The protected areas are broken up into 21 sites, most off the Louisiana coast.
