Beneath the Oil Slick

Since the oil spill began three weeks ago, most eyes and cameras have been focused on the widening, orange slick. But now, as experts argue that the flow rate could far exceed the government's estimate of 210,000 gallons a day, a team of independent scientists studying the water in and around the disaster zone have found another problem: stores of leaked oil lingering beneath the surface in long, stringy filaments and snowflake-like collections.

"It doesn't float right up on top as you would think," Raymond Highsmith of NIUST tells AOL News. "Some of it floats right under the surface, and some of it now looks like it's quite a ways down."

This is the start of a piece I just wrote for AOL News. What these scientists are doing is amazing, and important. Read the rest here.
