On April 20, 2010, the Deepwater Horizon Drilling Platform exploded and sank, causing the largest oil spill yet recorded. Samples from the oil spill were collected by Louisiana USGS scientists Greg Swayze and Charlie Demas and sent for analysis in Menlo Park, CA. The analysis team was lead by Bob Rosenbauer, who is a senior geologist at USGS and has performed similar research on petroleum fingerprinting. He also collaborated on a USGS report on the tar balls of southern California.
