To test feasibility of operating sidescan sonar from a small (22 ft) vessel in the very nearshore zone of Lake Erie and to ground truth via diving unique bottom features observed on previous sidescan sonar records.
Location
offshore Lorain and Vermilion, Ohio, Lake Erie, Great Lakes, United States, North America;
Summary
Approximately 25 nautical line miles (nlm) were run in both the nearshore zone and as site-specific lines over previously recorded features. A total of 14 dives were made (7 each by 2 divers) on 3 different sites. Bottom samples, descriptions and 8 mm video were collected on each of the 3 sites. On 1 site, a 1.78 m core was taken. This core was later extruded, described and subsampled.
