Detailed Description
Chirp 3.5-kHz subbottom profile from the June 2011 Langseth cruise, showing more than 60 m of sound-signal penetration in the vicinity of the southwest edge of the Baranof fan system. Profile shows a modern channel and levee running along the very edge of the vast Baranof system. Aggradational fan channels, such as this one, appear to build the margin upward and outward over time. Profile is located at the south end of MCS line 11.
