Summary

In September 2018, the U.S. Geological Survey, in collaboration with the U.S. Army Corps of Engineers, conducted high-resolution geophysical mapping and sediment sampling to determine the distribution of historical mine tailings on the floor of Lake Superior. Large amounts of waste material from copper mining, locally known as “stamp sands,” were dumped into the lake in the early 20th century, with wide-reaching consequences that have continued into the present. Mapping was focused offshore of the town of Gay on the Keweenaw Peninsula of Michigan, where ongoing erosion and re-deposition of the stamp sands has buried miles of native, white-sand beaches. Stamp sands are also encroaching onto Buffalo Reef, a large area of cobble/boulder [...]

Purpose

This dataset contains 500 shot point interval navigation for approximately 120.9 km of single-channel boomer, seismic-reflection data collected by the U.S. Geological Survey during cruise 2018-043-FA along Traverse Bay, Lake Superior. This information allows for spatial correlation of boomer seismic-reflection profiles images with other geophysical and sample data for investigating lake-floor morphology and stratigraphy in the area.
