Oil-spill berm

Detailed Description

Seafloor depths (rainbow colors) acquired by swath and single-beam bathymetric survey conducted around the berm in June 2011, with oil-spill berm and Chandeleur Island shorelines (black and brown, respectively) acquired by lidar survey conducted in March 2011. Repeated surveys will be conducted to monitor seafloor response to short-term berm and island evolution. During construction, approximately 4 million m3 of sediment was excavated from a borrow site 2 km north of the berm.
