Figure 1. Ongoing geological and geophysical cha racterization of the New Jersey "natural laboratory," part of which is the MAT. Primary proposed drillsites for Leg 174A are 8B and 9B on the shelf; secondary sites 13A-D are located on the upper slope. The high-resolution MCS coverage (collected aboard R/V Oceanus in 1995) was used to select all sites except 13A, which is located on a Ewing MCS line (see Fig. 3 and 13A site summary). Swath backscatter/bathymetry data coverage shown was acquired in the Spring of 1996 (Goff et al., 1996); subsequent acquisitio n (November 1996) is not shown, but now includes the secondary upper slope sites.
