"As part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, twenty-two and one SAP were collected from lakes Dufresnoy and Lac Petit Dufresnoy, Quebec, respectively, on July 19, 2014. There is good penetration of the sub-bottom along many of the profiles. Three depositional facies can be identified within the SAP returns that represent lacustrine, glaciolacustrine and mass movement deposits. In many profiles, multiple occurrences of mass movement deposits can be identified. The profiling reveals that Lac Dufresnoy is a suitable basin for follow-up detailed profiling and core collection to further investigate the mass movement deposit(s)"--Abstract, page 2.
