Scientists conducted field and laboratory experiments using oil and Corexit dispersant to uncover the reasons harmful algal blooms, also known as Red Tides, can occur after an oil spill.
Researchers combined laboratory experiments and molecular simulations to examine how two Corexit surfactants – DOSS (dioctyl sulfosuccinate) and Span 80 – individually affect oil aerosolization.
Scientists developed and validated a high-resolution mass spectrometry method to fill data gaps in existing methods that detect the surfactant DOSS, a significant Corexit component, in sediments near the Deepwater Horizon spill site.
Scientists observed in laboratory experiments the formation of extracellular polymeric substances (EPS, a natural microorganism excretion) when phytoplankton and their associated bacteria were exposed to Corexit dispersant.
Oil spill responders currently have the option to treat oil spills with a synthetic dispersant called Corexit, however scientists continue to search for alternatives. In this search, scientists seek to develop an understanding of the specific mechanisms that drive dispersion and identify an effective combination of food-grade components.
Research about commercial dispersant safety has seen increased efforts to identify benign alternatives and improve current dispersant systems since the Deepwater Horizon oil spill.
Scientists conducted experiments to determine the effects of hypoxia (reduced oxygen conditions), a seasonal occurrence in the northern Gulf of Mexico, and oil spill contaminants on sheepshead minnow larvae.

Mount Allison University Researcher Part of a $7.25 M Grant to Study Effects of Gulf of Mexico Oil Spill – February 26, 2015 Mount Allison University geography and environment professor Dr. Zoe Finkel is collaborating with researchers in a multi-university consortium that received $7.25 million to study the impact of the Deep Water Horizon oil…
Chemists from Oregon State University developed a method that detects and measures the chemical composition of the four Corexit surfactants in seawater.
Scientists from Louisiana State University evaluated bursting bubbles as a pathway for hydrocarbons to move from the sea into the air and they investigated the influence of Corexit 9500A on this process.
