Oil Spill Samples Arrive from Louisiana
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.

Baseflow measurements of field parameters
The team of USGS scientists collected stream water samples before and after rainfall events for this study. In this photo a USGS scientist is taking measurements of field parameters (dissolved oxygen, water temperature, specific conductance, and pH) from New York Branch, Iowa, at low flow (baseflow) conditions.
