GoMRI ScienceResearch StoriesRFP-V Project Highlights RFP-V Drennan: Using Complementary Simulations to Improve Oil Tracking under Hurricane Conditions 4041a

Interactions among wind, waves, and upper-ocean currents are essential factors in predicting oil slick transport and fate. These complex interactions, however, make capturing their dynamics in simulations challenging, especially when turbulent weather conditions are present. The Gulf of Mexico Research Initiative recently awarded Dr. William Drennan a grant to study how wind-wave-current interactions affect oil Read More

GoMRI ScienceResearch StoriesRFP-V Project Highlights RFP-V Shay: Building a Rapid Response System for Predicting Water Column Processes and Oil Fate 4101a

As the Deepwater Horizon oil spill unfolded, there were concerns that the Loop Current might transport oil out of the Gulf to the Florida Keys and up the eastern seaboard. This possibility highlighted the need for quick predictions of oceanic flows and subsurface hydrocarbon distribution during and after a spill. Because physical and biochemical processes Read More

GoMRI ScienceResearch StoriesRFP-V Project Highlights RFP-V Thomas: Building a Benthic Genome Database for Improved Oil Spill Monitoring 4116a

Meiofauna are invertebrate organisms that live in seafloor sediments. These marine creatures perform ecosystem functions such as trophic transfer, biogeochemical cycles, pollution removal, and sediment transport stability. Sensitive to environmental events such as oil spills, meiofauna are valuable bioindicators of impacts from contamination. However, their small size and our limited knowledge about these organisms’ community Read More

Marshes depend on a healthy, well-functioning complex of plants, microbes, and benthic communities to support the environmentally and economically important ecosystem services they offer, such as reducing storm surges and providing nursery grounds for many species. Researchers have been conducting studies assessing Louisiana marsh flora and fauna after the 2010 Deepwater Horizon oil spill and Read More

Researcher Oscar Garcia-Pineda demonstrates some of the methods the team uses to collect imagery and samples of floating oil near MC20. (Provided by Villy Kourafalou) The flow of the Mississippi River into the northern Gulf of Mexico may have caused circulation patterns and fronts that significantly influenced the transport and fate of Deepwater Horizon oil.

GoMRI ScienceResearch StoriesRFP-V Project Highlights RFP-V Miller: Identifying Toxic Components in Fresh and Weathered Crude Oil 3806a

Hydrocarbons associated with oil spills can have harmful effects on humans and organisms, yet little is known about the specific compounds that contribute to toxicity. The ability to identify and quantify oil’s key toxic compounds will help improve predictions of future spills’ effects on human health and marine ecosystems. The Gulf of Mexico Research Initiative Read More

Living inside the roots and leaf tissues of marsh grass are bacteria and fungi known as endophytes that help promote plant growth. Since some endophytes can also help degrade petroleum that the plants absorb, it is possible they could be a natural tool to help clean up oil buried in marsh soils. The Gulf of Read More

GoMRI ScienceResearch StoriesRFP-V Project Highlights RFP-V Meneveau: Improving How Oil Spill Models Predict Plume Dispersion and Transport A Large Eddy Simulation of oil droplet (color contours) and gas bubble (white lines) plumes emerging from 1500 m below the surface into a stratified ocean, including 3D Coriolis force and west-to-east current effects. (Simulation performed by Dr. Di Yang, University of Houston)

Deep ocean oil plumes that formed from the Deepwater Horizon spill and their subsequent rise through the water column were greatly influenced by physical mixing mechanisms such as turbulence, Langmuir circulations, and sub-mesoscale eddies. These mixing processes are crucial variables needed for existing models to accurately predict a plume’s overall size, shape, and transport direction. Read More

Evidence suggests that when oil interacts with particles in the marine environment, it can form larger, rapidly sinking particles called marine snow. These oily aggregates are often transported from the sea surface to the seafloor. The snow falls more like a heavy blizzard than a light flurry for large discharges such as the Deepwater Horizon Read More
