The Present is the Key to the Past
For marine scientist David Hollander (USF), there’s an idiom that underscores much of what inspires him about geology: “The present is the key to the past, but the past provides a window to see into the future.” With that in mind, he and his team have studied the ecological impacts of 1979’s Ixtoc oil spill in the southern Gulf of Mexico in order to predict how long recovery might take from 2010’s Deepwater Horizon blowout in the northern Gulf.
After a difficult research trip to Mexico’s Yucatan Peninsula and countless hours of study back at the USF labs, the team discovered that it takes roughly a decade for most of the system to clean and restore itself; however, it does not return to the same ecological position. What occurs is an ecological evolution to another stable state.
PODCAST OF THE WEEK
GulfCast: The LASER Cruise: Drifters
When the Deepwater Horizon oil spill occurred, it was difficult to know where the oil might end up. The LASER team’s goal was to study how the oil spreads out via ocean currents, so they could create predictive models for future spills. Thousand of drifters would be required to execute the experiment, but existing drifters were extremely expensive due to the GPS component. Two years were spent designing specialized drifters into a low-cost, packable version that performs well in the open ocean and is biodegradable.

Grad Student Karthikeyan Uses Genetics to Understand Microbial Oil Degradation in Beach Sands
Petroleum hydrocarbons released by oil spills can accumulate on beaches and in nearshore sediments, potentially creating health risks for humans and coastal organisms. However, the highly variable conditions of beach environments make it difficult to determine the long-term behavior and fate of hydrocarbons in sands and sediment.
Smruthi Karthikeyan combines bioinformatics and oil degradation data to examine microbial responses to oil in beach environments and identify populations that act as bioindicators of oil degradation and toxicity. Documenting microbial indicators and producing oil degradation models for environmental managers can help with future oil spill response plans for coastal zones.
