Field Activity 2018-043-FA

Identifier 2018-043-FA
Purpose To collect baseline geophysical data on the distribution and thickness of reworked mine tailings on the lake bottom near Buffalo Reef.
Location Big Traverse Bay, Lake Superior, Michigan, United States
Summary Covered approximately 309 square kilometers of Reson T20P (dual head) bathymetry and backscatter along 387 kilometers of survey lines. Collected (first) 3 days of Boomer data along 115 kms of tracklines. Collected 4 days of 424 Chirp data along 272 kms of tracklines. Collected 17 sediment samples on last day (Sept 26th)
Info derived bathymetry, backscatter, modern sediment thickness, depth to basement (i.e., top of Pleistocene)
