Oil, gases, and bubbles jet out together during a deep-ocean petroleum blowout, and the oil quickly breaks up into different-sized droplets. Predicting the sizes of these droplets is critical to determine how long it will take the oil to reach the ocean’s surface and the resulting oil slick’s size.

Outreach specialists working with science consortia, funded by the Gulf of Mexico Research Initiative (GoMRI), reflected on their collective multi-year efforts for insights gained and lessons learned. These reflections resulted in recommendations for creating, managing, and implementing scientific outreach plans.

When the Deepwater Horizon incident occurred, not much was known about how conditions in the deep sea would affect oil biodegradation. Juan Viamonte uses high-pressure reactors that simulate conditions at depth to observe microbial degradation and help predict what might happen should another deep-ocean oil spill occur.

The Gulf of Mexico Research Initiative is pleased to announce a new Sea Grant publication about how oysters, which play a critical role in a healthy coastal wetland, fare when faced with oil exposure. The outreach publication also discusses how the Deepwater Horizon incident and subsequent response efforts affected oysters, a vital part of Louisiana’s seafood industry which is the nation’s second-largest seafood supplier.

Researchers analyzed the combined effects of photooxidation and biodegradation on sand patties associated with the Deepwater Horizon incident. The scientists found that irradiation contributed to increased concentrations of dissolved organic carbon, which leached from sand patties penetrated by seawater.

Louisiana State University scientists quantified Louisiana island erosion pre- and post-Deepwater Horizon to determine the shoreline retreat rate when oiled, the length of time that oiling effects lasted, and whether or not there was recovery.
