Video: Low-oxygen dead zone found on seafloor off Alabama coast
July 04, 2010
Recent testing by the Press-Register indicates that a low-oxygen dead zone is hugging the seafloor in places along the Alabama coast, with levels far below the threshold required to support life.
The newspaper sampled oxygen levels in the water column every 5 feet from the surface to the bottom at two natural gas platforms, using an electronic meter made by YSI Inc. The meter is a standard piece of equipment used by state and federal agencies for such field testing.
