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.
Scientists analyzed microbial communities on beaches oiled by the Deepwater Horizon spill and found taxonomic and functional changes after hydrocarbon exposure.
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.
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.
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.
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.
