Data Type(s): Sonar: Single Beam, Environmental Data: Turbidity, Sampling: Biology, Sampling: Chemistry, Sampling: Geology, Location-Elevation: Navigation, Sonar: Sidescan
Scientific Purpose/Goals: 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.
Vehicle(s):
Start Port/Location: Sandusky, OH
End Port/Location: Sandusky, OH
Start Date: 1992-08-14
End Date: 1992-08-23
Equipment Used: Echosounder, Acoustic resuspension measurement system, Sidescan sonar, SCUBA, Loran-C
Information to be Derived:
Summary of Activity and Data Gathered: 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.
