| Purpose | Geophysical mapping, sediment sampling and photographic characterization of mine spoils on lake floor | ||||||||
| Location | Big Traverse Bay, Lake Superior | ||||||||
| Summary | Collected multbeam depth and backscatter data along 375 kms (14 sq kms) of survey lines using a Reson T20-P Dual-head multibeam sonar 5-11 August. Collected bottom photographs, video and grab samples at 94 locations using the mini-SEABOSS.13-16 August. | ||||||||
| Info derived |  Bathymetry, backscatter, sediment distribution, texture and composition, bottom video and photographs | ||||||||
