Scientists from the Woods Hole Oceanographic Institution, MA, embarked on June 17 for a 12-day research effort in the Gulf of Mexico to characterize subsurface oil plumes. They are aboard the research vessel Endeavor conducting projects funded through the National Science Foundation rapid response program. The research should help answer questions about the extent, chemical composition and biological impact of subsea plumes. The research pulls together some of the most advanced technology for underwater chemical sampling and underwater autonomous vehicles. The team has studied archived oil spill reports stretching back 40 years and has received data and advice from colleagues at other institutions who recently surveyed the site. (Source: NSF, 06/22/10)
