| Abstract | As part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, 25 profiles were collected at Swan Lake, Ontario, on August 17, 2015. The quality of the returns ranges from good to no
penetration, probably reflecting variations in the present of methane gas in the sediments. Three facies are present within the SAP returns that represent lacustrine, glaciolacustrine and subaqueous mass transport deposits. The profiles collected
from Swan Lake demonstrate the presence of mass transport deposits within this basin. |
| Summary | (Plain Language Summary, not published)
This Open File is a release of sub-bottom profile data collected from Swan Lake, Ontario. The profiles reveal lacustrine, glaciolacustrine and submarine
landslide deposits preserved in the modern lake bed. |
