A Florida State University researcher and his team have developed a comprehensive analysis of oil in the Gulf of Mexico and determined how much of it occurs naturally and how much came from the 2010 Deepwater Horizon spill.
(From Science Daily) — And more importantly, their data creates a map, showing where the active natural oil seeps are located.
The research was recently released online by the Journal of Geophysical Research Oceans and is also the basis for a paper with researchers at Columbia University published in Nature Geoscience.
In total, 4.3 million barrels were released into the Gulf from the oil spill versus an annual release of 160,000 to 600,000 barrels per year from naturally occurring seeps, according to the new results.
“This information gives us context for the Deepwater Horizon spill,” said FSU Professor of Oceanography Ian MacDonald. “Although natural seeps are significant over time, the spill was vastly more concentrated in time and space, which is why its impact was so severe.”
