Grad Student Hamilton Hunts Oil Using Microbes
Bryan Hamilton never planned to be a microbiologist, but when the opportunity arose to study microbes that produce biosurfactant in response to oil exposure, he was drawn in completely.

Study: Different Dispersant Surfactants Help and Hinder Oil-Degrading Bacteria
Scientists studied the interactions of the oil-degrading bacterium Alcanivorax borkumensis with oil across oil-water interfaces that had varying amounts of different surfactants.

Grad Student Cruz Bridges Disciplines to Track Tiniest Plankton’s Response to Oil Spill
Jarrett Cruz has been all over the world studying nannoplankton, a marine species he did not know existed when his journey began. Jarrett’s research into these minuscule creatures spans both biology and geology as he studies the impact of oil on nannoplankton that live in the Gulf of Mexico.

Study: Early-Responder Microbial Groups Differed Over Time in Oiled Beach Sands
Scientists analyzed microbial communities on beaches oiled by the Deepwater Horizon spill and found taxonomic and functional changes after hydrocarbon exposure.

Study Shows Hypoxia and Dispersed Oil May Increase Fish Mortality
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.

Why Grad Student Martinec Digs the Seafloor
Ceil Martinec picks microscopic creatures out of mud collected from deep in the Gulf of Mexico. She is looking for possible lingering effects of the 2010 oil spill on sediment-dwelling animals and making some exciting discoveries along the way.

Studies Identify Oil Spill Effects in Deep Sea Fish
Two studies show that some demersal fishes living in waters likely contaminated by the Deepwater Horizon oil spill exhibited elevated hydrocarbon concentrations and experienced shifts in diet and trophic level.

Study Suggests Biodegradation Strongly Influences Oil Spill Transport Predictions
Scientists simulated twenty subsurface spill scenarios, using data reflective of the Deepwater Horizon spill, and found large differences in transport predictions when model parameters included bacterial consumption (biodegradation) of oil droplets.

Grad Student Deb Adhikary Sees How Burrowing Shrimp Help Microbes Deal with Oil
Nihar Deb Adhikary uses his veterinary training and microbiology research to better understand the connections between oil fate, microbial degradation, and sediment-dwelling organisms such as shrimp and clams.
