The Gulf oil disaster reminds me of that old Donald Rumsfeld chestnut, the one about known-knowns and known-unknowns. With a massive, ongoing gushing oil spill, and an enormous ecosystem at risk, we're in the realm of the "known unknown" â€“ we know that there is a huge amount of oil moving through the Gulf, but no oneâ€™s quite sure exactly where it is or where itâ€™s going.
A group of federal agencies, including NOAA, Fish and Wildlife Service, Bureau of Land Management and the National Park Service are trying to push us into the "known known" category with teams sent out on what are essentially reconnaissance missions. Two months into the oil disaster, theyâ€™re still grappling to understand the impacts on shorelines, turtles, mammals and more.
Last Thursday, for the first time, NOAA allowed a small group of ocean conservation activists to shadow a crew working on discovering the location and severity of subsurface oil. I joined our senior campaign director, Jackie Savitz, along with scientists and campaigners from Ocean Conservancy and the Gulf Restoration Network in a couple of skiffs that tailed the NOAA crew for a few hours on the water just east of Grand Isle, La.
Before we embarked, NOAA restoration specialist Sean Meehan gave us the rundown as we stood on the dock in Jean Lafitte, about 25 miles south of New Orleans. A jovial guy, Meehan is an experienced marine researcher, but even he acknowledged the unique difficulty of locating subsurface oil.
