AbstractAs part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, 22 profiles were collected at Lac Taschereau, Quebec, on August 21, 2015. There generally is good penetration into the sub-bottom along most profiles, except in the central and northern portions of the basin where there was no penetration. Three depositional facies are present within the SAP returns that represent lacustrine, glaciolacustrine and mass transport deposits. The survey of Lac Taschereau demonstrates that multiple stratigraphic occurrences of mass transport deposits are present within this basin.
Summary(Plain Language Summary, not published)
This Open File is a release of sub-bottom profile data collected from Lac Taschereau, western Quebec. The profiles reveal lacustrine, glaciolacustrine and submarine landslide deposits preserved in the modern lake bed.
