Bartlett Cove Seismic Profile

Bartlett Cove Seismic Profile; see caption below.

This 3.5 kHz acoustic profile (top) shows part of the buried portion of the lateral moraine that marks the entrance to Bartlett Cove. The interpretive sketch (bottom) shows well-bedded fine grained sediment (sandy to silty) from 2 to 20 m thick that covers the very irregular morainal surface. Note "g?", which marks the possible presence of gas-charged sediment. Vertical exaggeration is approximately 4X.
