Purpose
|
|
Employ video and still photography, and high-resolution subbottom
|
|
profiling to groundtruth and quantify the sidescan sonar mosaic and acoustic
|
|
data collected in 1993 of the US Army Corps of Engineers South Oahu Deep Ocean
|
|
Dredged Material Disposal Sites. We are attempting to acoustically characterize
|
|
the anthropogenic effects on the seafloor and near-surface substrate over the
|
|
disposal sites. Through photography and bottom sampling we can quantify the
|
|
Sonar Mosaic and acoustics collected in the 1993 field operations.
|
|
|
Summary
|
|
Nearly 100 hours of underwater video and still photography, and over 200 km of high-resolution 3.5 kHz subbottom profiles over the deep ocean disposal sites.
