EESA Researchers Solve Deepwater Horizon Mystery1 min read

Deepwater Horizon Oil Spill

The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 is one of the most studied spills in history, yet scientists haven’t agreed on the role of microbes in eating up the oil. Now a research team at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has identified all of the principal oil-degrading bacteria as well as their mechanisms for chewing up the many different components that make up the released crude oil.

The team, led by Gary Andersen—a microbial ecologist and senior scientist at Berkeley Lab’s Earth & Environmental Sciences Area—is the first to simulate the conditions that occurred in the aftermath of the spill. Their study, “Simulation of Deepwater Horizon oil plume reveals substrate specialization within a complex community of hydrocarbon-degraders,” was just published in the Proceedings of the National Academy of Sciences.

“This provides the most complete account yet of what was happening in the hydrocarbon plumes in the deep ocean during the event,” said Andersen. Berkeley Lab’s Ping Hu, the lead author of the study, added: “We simulated the conditions of the Gulf of Mexico oil spill in the lab and were able to understand the mechanisms for oil degradation from all of the principal oil-degrading bacteria that were observed in the original oil spill.”

  Scientists from the Energy Geosciences Division have begun working with European partners on three new geothermal research projects through the Department of Energy’s membership in GEOTHERMICA, a transnational consortium that combines the in-country financial resources and research expertise of 15 participating countries to demonstrate and validate novel concepts in geothermal energy use. This marks the…

EESA Senior Scientist Talks Earthquake Building Resilience1 min read

Berkeley Lab senior scientist David McCallen leads a subproject called Earthquake Sim, or EQSIM, for the DOE’s Energy Exascale Computing Project. He is also professor and director of the Center for Civil Engineering Earthquake Research in the Department of Civil and Environmental Engineering at the University of Nevada, Reno. McCallen recently spoke with Scott Gibson of…

EESA Scientist Coauthors New Comprehensive Guide on Removing CO2 from the Atmosphere2 min read

Berkeley Lab researchers are working on ways to sequester more carbon in soil, including through agricultural practices. (Credit: Berkeley Lab) Scientists say that any serious plan to address climate change should include carbon dioxide removal (CDR) technologies and policies, which makes the newly launched CDR Primer an especially vital resource, says Berkeley Lab scientist Margaret Torn, one…
