Scientists find dead and dying coral covered with a brown substance 7 miles from BP oil spill site

Thursday, November 04, 2010, 10:00 PM A brown substance is killing coral organisms in colonies located 4,600 feet deep about seven miles southwest of the failed BP Macondo oil well, according to scientists who returned Thursday from a three-week cruise studying coral reefs in the northern Gulf of Mexico. The finding is the first case in which researchers have found evidence that living organisms in the deepwater area near the well site might have been killed by oil from the spill. Penn State University biology professor Charles Fisher, chief scientist aboard the NOAA ship Ronald H. Brown said soft coral in a 15-meter to 40-meter area was covered by what appeared to be a brown substance. “Ninety percent of 40 large corals were heavily affected and showed dead and dying parts and discoloration,” according to a news release reporting the findings by Fisher and other scientists issued jointly by NOAA and the Bureau of Ocean Energy Management, Regulation and Enforcement, which co-sponsored the research. “Another site 400 meters away had a colony of stony coral similarly affected and partially covered with a similar brown substance.” “While this mission was not designed to be focused on oil spill research, the timing and location provided an opportunity to observe any impacts to our research areas,” Fisher said in the news release. Fisher was unavailable for further comment on Thursday night. The release said the scientists “observed dead and dying corals with sloughing tissue and discoloration.” …
