Vessel Needed for Collecting Seafloor Images Using DIDSON and Video Imagery

Deadline for written questions: 3.16.2018
Deadline for submissions: 3.23.2018

This work will make tows with a sled equipped with DIDSON and video imaging equipment to collect seafloor images across the swept area of a bottom trawl equipped with elevated trawl sweeps (designed to reduce seafloor contact and interactions with small macroinvertebrates [e.g., Dungeness crab, Echinoderms]). The DIDSON sonar and video imaging will be used to estimate the degree of seafloor contact made by examining the cross-section of the sweeps disc tracks formed on the seafloor and the texture of the seafloor between the disc tracks.
