| Abstract | As part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, 23 SAP were collected from Lac Joannès, Quebec, on August 22, 2015. Good penetration of the sub-bottom was obtained within the
profiled areas. Three depositional facies are present within the SAP returns that represent lacustrine, glaciolacustrine and mass transport deposits. The profiles collected from Lac Joannès demonstrate the presence of mass movement deposits within
this basin. Relatively deep water conditions in some of the profiled areas could represent a challenge to coring, depending on the coring equipment used. |
| Summary | (Plain Language Summary, not published)
This Open File is a release of sub-bottom profile data collected from Lac Joannès, western Quebec. The profiles reveal lacustrine, glaciolacustrine and
submarine landslide deposits preserved in the modern lake bed. |
