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.

When Deepwater Horizon oil approached coastal environments, it was unclear how river water entering the Gulf of Mexico would affect the oil’s transport and fate. Steve Dykstra uses drifters and ship-deployed sensors to study how freshwater plumes disperse in the coastal environment over different seafloor topography.

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.

Scientists assessed the behavior of a Florida river plume to determine how it might influence the transport and dispersion of surface oil near coastal regions. The researchers found that the near-surface measurements of dissipation at the front’s bounding edge were four orders of magnitude larger than the environment beneath.

Kelsey Rogers looks for evidence of oil and methane intrusion into Gulf of Mexico water and sediment, but finding these hydrocarbons is only the beginning of her work. Like a scientific crime scene investigator, Kelsey analyzes the chemical fingerprints of oil and gas and uses them to identify their source, such as from an oil spill or a natural seafloor seep.

Scientists from the University of South Florida used circulation models to conduct a tracer simulation and compared output patterns with ecological analyses to determine the possibility that hydrocarbons from the Deepwater Horizon oil spill could have moved onto the West Florida Shelf

CARTHE Researcher Named UCAR Trustee
Dr. Shuyi Chen is an expert in extreme weather prediction and an ocean science professor at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science. Dr. Chen was recently selected as a board member for the University Corporation for Atmospheric Research (UCAR), a nonprofit consortium that targets atmospheric and related Earth system sciences research and training. Congratulations!
C-IMAGE’s The Loop Podcast Highlights Deepwater Horizon’s Risks to Fish
The podcast’s most recent episode features Mote Marine Laboratory’s Dana Wetzel and Kevan Main, who analyze how fish’s bodies recover after exposure to small oil doses in their food, water, or seafloor sediments. Wetzel, Main, and Matt Resley discuss how understanding the risks fish have during oil spills can assist oil spill response decisions.
