Determining "Ground Truth" in the New Jersey STRATAFORM Natural Laboratory
Abstract
UTIG is integrating "nested" seismic data off New Jersey with subsurface samples, as they become available. This STRATAFORM goal is elusive, because "ground-truthing" of seismic sequence boundaries and intervening facies by sampling at relevant depths is incomplete Objectives remain: (1) to study sea-level changes over the past ^35 Ma, and (2) to determine the effects of depositional and erosional processes on the preserved sediment record, from the seafloor to subbottom depths of ^lOO m. A comprehensive characterization of the uppermost middle-outer New Jersey shelf is underway, building upon multibeam backscatter/bathymetric seafloor images and 2D/3D ultra-high resolution geophysical control. Results from ODP Leg l74A (1997) are published (see http:www-odp.tamu.edu/publications/). Since UTIG collected 3D Huntec data on the New Jersey shelf(1989), the primary continuing activity has been ground-truthing surficial images. Short piston cores were acquired after the 1989 survey; short vibra-cores were collected in association with a second 3D survey in 1993; long coring is now being pursued as part of Geoclutter.
