Structure of the Upper Monterey Submarine Fan Valley.

Abstract

Seismic and 3.5 kHz acoustic reflection profiles were collected over the Monterey Submarine Fan Valley on two separate cruises. The 3.5 kHz profiles show the flatness of the channel bottom and the difference in levee heights on either side of the channel. The seismic records show a channel migration by deposition. A secondary channel was observed beneath the western levee (right-hand levee looking downstream) of the Upper Monterey Submarine Fan Valley. It is believed that the Monterey Fan Valley and the secondary channel had different sources of sediment and that the secondary channel was deprived of its sediment supply approximately 1.9 million years ago.
