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. Jarrett, a geology Ph.D. student at Read More

Publication Highlights Study: Early-Responder Microbial Groups Differed Over Time in Oiled Beach Sands Jonathan Delgardio and Will A. Overholt (Georgia Institute of Technology) collect samples from a Pensacola Beach sand trench with oil layers. (Photo by Markus Huettel)

Scientists analyzed microbial communities on beaches oiled by theDeepwater Horizon spill and found taxonomic and functional changes after hydrocarbon exposure. Taxonomically, there was an increase in specific oil-degrading bacteria followed by a return of more diverse non-oil degrading bacteria a year later. While these returning microbes were typical for beach sand, they were different from Read More

Publication Highlights Study Shows Hypoxia and Dispersed Oil May Increase Fish Mortality Subham Dasgupta (left) and Irvin Huang (right) used this glove box to create hypoxic conditions for this study.  (Photo provided by Anne E. McElroy)

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. Hypoxia as a co-stressor with Corexit® 9500 or Corexit-dispersed oil reduced larvae survival by 80% to 90%. There were no significant effects observed to the larvae Read More

GoMRI Students Why Grad Student Martinec Digs the Seafloor RFP-IITroyGroup_Landers_1639a

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. “We are documenting new species for the area and studying the natural links or relationships between Read More

Publication Highlights Studies Identify Oil Spill Effects in Deep Sea Fish A red snapper collected from Gulf of Mexico waters for oil spill impact studies. (Photo provided by Joseph Tarnecki)

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 in the study PAH Exposure in Gulf of Mexico demersal fishes, post-Deepwater Horizon (Environmental Science & Technology) assessed the bile of golden tilefish, king Read More

Publication Highlights Study Suggests Biodegradation Strongly Influences Oil Spill Transport Predictions biodegradation_1742b

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. Simulations with biodegradation indicated that tiny oil droplets remained deeper by hundreds of meters and were less spread out by thousands of kilometers compared Read More

GoMRI Students Grad Student Deb Adhikary Sees How Burrowing Shrimp Help Microbes Deal with Oil Nihar conducts a 14C-radiolabeled naphthalene assay in a radioactive laboratory to determine naphthalene degradation rate using sediments after each greenhouse microcosm experiment.

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. “Oil in coastal sediment can significantly impact the animals that live there,” he said. “I think it will be amazing if we can show that these benthic Read More

Teachers and Students AUV Jubilee: CONCORDE Coordinates Gulf-Wide Data Collection Event AUV_Jubilee_1614d

The AUV Jubilee was a premier event to coordinate autonomous underwater vehicles, known as AUVs or gliders, and other in situ operations in the Gulf of Mexico during July 2015. Called a “big science party,” the name used the term Jubilee to refer to the Gulf Coast phenomenon during which naturally occurring hypoxia pushes fishclose Read More

Teachers and Students ADDOMEx Researcher Helps Introduce Teachers to Engineering James_Chiu_1579

James Chiu presented the ADDOMEx Consortium’s research to nearly seventy teachers participating in a program called Team-E Science, which will help them better understand engineering concepts. The program is part of a three-year endeavor to implement engineering curriculum in Merced and Mariposa county schools. Underrepresented minority groups make up more than half of the student body Read More

GoMRI Scientists GoMRI Interview with Dr. Debra Murie 2645

Dr. Debra Murie from the University of Florida answered a few questions about her RFPII project, Spatial and Temporal Effects of the Deepwater Horizon Oil Spill on Growth and Productivity of Recreational and Commercial Fisheries in the Gulf of Mexico. The PIs on the project, in addition to Dr. Murie, are Dr. Daryl Parkyn and Dr. Read More
