Here are highlights from selected GoMRI-funded peer-reviewed publications related to advancements in knowledge about physical ocean processes that affect how an oil spill moves.

Hydrocarbon-degrading microbes living in ocean environments consumed and metabolized oil droplets following Deepwater Horizon, which significantly influenced the oil’s fate in the Gulf of Mexico.

Scientists assessed an economical 2D model simulation of deep-ocean oil plume dynamics against 3D model results using conditions similar to Deepwater Horizon to better understand point-source buoyant convection, which affects the oil’s spreading rate and environmental impact.

A 12-day science expedition on the exploration vessel Ocean Intervention II embarks June 11 to investigate how oil, gas, and chemical dispersants affect marine life and their environment deep in the Gulf of Mexico. Scientists and outreach personnel onboard the vessel will interact with the public and school-age children using streaming video, social media, and question-and-answer sessions.

Webinar Series on Human Health Impacts Following Oil Spills
The Sea Grant Oil spill Outreach Team is hosting three online workshops titled "Detecting the true, potential, and perceived impacts to human health following an oil spill." Question and answer sessions will follow presentations. The first workshop was held on June 8th and addressed impacts on air quality. The second will cover impacts on water quality (date TBD), and the third will cover impacts on human health (date TBD). More information is available at: https://gulfseagrant.org/oilspilloutreach/presentations/webinar-series-detecting-the-true-potential-and-perceived-impacts-to-human-health-following-an-oil-spill/
Workshop Report on Emergency Responder and University Researcher Collaboration
A report is now available that draws from workshops hosted by the Sea Grant Oil Spill Outreach Team where emergency responders and oil spill science researchers from around the Gulf of Mexico gathered to learn from one another. The report is available at: http://masgc.org/oilscience/Researcher-Responder-Workshop-Report.pdf
Workshop Report on Delaware Bay Oil Spill-Related Needs and Resources
A report is now available on the proceedings from the January 2019 workshop hosted by the Sea Grant Oil Spill Outreach Team titled "Oil in the Bay: 15 years after the Athos I spill." The Gulf Sea Grant Team partnered with the Sea Grant programs of Delaware, New Jersey, and Pennsylvania and hosted a special session at the Delaware Estuary Science and Environmental Summit that highlighted oil spill-related needs and resources in the Delaware Bay and strengthened networks.The report is available at http://masgc.org/oilscience/Summary-OilSpillSession-PDEsummit.pdf
Upcoming Sea Grant Oil Spill Webinars
Keep your eye out for these events that are in the works that the Sea Grant Oil Spill Outreach Team will host: "Breaking it down: Oil in the environment;" "Every snow often oil, microbes, and sediment get together and sink" (on marine oil snow); and "Oysters: Adapting to a changing Gulf, a three-part series." Details will be available at https://gulfseagrant.org/oilspilloutreach/presentations/
Call for Papers: Predicting Hydrocarbon Fate in the Ocean
Editors invite papers that explore the fate of hydrocarbons in the ocean using multi-component numerical models, especially studies that explore the relationship between two or more processes, including microbial ecology, sediment transport, oil/gas plumes, and physical mixing and transport processes. They also welcome papers on related experimental aspects of these topics, i.e. that can contribute to modeling parameterization, calibration, and verification. Read more here.
