Purpose
|
Core through Holocene mud layer on shelf and recover material
|
from beneath underlying shelf-wide unconformity believed to represent
|
Holocene transgression event.
|
Core and recover material filling inner-shelf paleochannels that represent
|
buried channels cut during lower sealevel stands.
|
|
Information to be Derived
|
Age and composition of material underlying shelf unconformity through C-14 dating or other analyses. Age and composition of material filling paleochannels.
|
|
Summary
|
22 Cores were recovered averaging about 2.5m in length with the longest, 5.8m in length.

Notes
|
Vibracoring was carried out with the services of TEG Oceanographic
|
Services of Santa Cruz, owner and operator of the Vibracore system. Weather
|
conditions were mostly good. Found operations viable up to wind conditions of
|
15 knots. No anchoring required; manuevered, using DGPS, to stay on positions
|
of sites selected along existing seismic lines.
