Researchers described, for the first time, the dynamics and interactions of regional ocean flows with both anticyclonic eddies (circulating clockwise) near Cuba’s northern coast (dubbed “CubANs”) and cyclonic eddies (circulating counter-clockwise) along Florida’s southern coast.

The National Academies of Science, Engineering, and Math released their evaluation findings that assessed the effects and efficacy of dispersants as an oil spill response tool.

Petroleum hydrocarbons buried in sandy beaches are protected from tides and UV light and, thus, may persist longer in the environment than oil on the beach surface.

Scientists conducted mesocosm experiments with natural microbial communities to compare oil emulsion and dispersion mechanisms by microbial secretions of exopolymeric substances, EPS, also known as gels, and Corexit, a dispersant.

Researchers designed an automated network-based classification method to process large acoustic datasets and identify distinct dolphin click types without requiring prior knowledge of their distinguishing features. The method identified seven click types from over 50 million echolocation clicks recorded in the Gulf of Mexico – six clicks of unknown origin and one click belonging to the Risso’s dolphin species.

Collaborative Workshop Series: Regional Priority Setting for Health, Social, and Economic Disruption from Spills
A series of regional workshops is presented by the Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine; the Gulf of Mexico Research Initiative; and various Sea Grant partners. The series focuses on public health, social disruption, and economic impacts. Join scientists and emergency response personnel as they come together and learn about collaborations before, during, and after an oil spill. See flyer here.
