High-resolution seismic-reflection profiles collected aboard R/V GYRE, cruise GYRE 80-G-7A, over the continental slope and upper continental rise, offshore New Jersey

During August 1980, the U.S. Geological Survey (USGS) collected 982 km of single-channel seismic-reflection data on the Continental Slope and upper Rise between Lindenkohl Canyon and Toms Canyon, off New Jersey (fig. 1). The work was conducted aboard R/V GYRE (cruise 80-G-7A). The trackline grid of this cruise extends and supplements a grid of seismic-reflection lines collected by the USGS over this area in 1978 and 1979 (Robb, 1980a, b). These data were collected in cooperation with the Bureau of Land Management (Memorandum of Understanding AA851-MUO-18) to map the geology and the topography of the area in order to identify potential geologic hazards to oil and gas exploration and development. The suite of profiles that was collected includes 40-in3 airgun (recorded as 4-second and 2-second) and 800-J sparker (recorded as 1-second) profiles and 3.5-kHz bathymetry, recorded as 1-second profiles. All times represent two-way travel times. Details of the sources, cables, and instruments, as well as filter settings, are shown in table 1.

Geomorphology and sediment stability of a segment of the U.S. continental slope off New Jersey

The morphology of complex deposits of Pleistocene sediments covering the upper continental slope between Lindenkohl Canyon and South Toms Canyon results from both depositional and erosional processes. Small slump or slide features were detected primarily on the flanks of canyons or valleys and were observed to occur only within Pleistocene-aged sediments. Eocene to Miocene sediments are exposed over much of the mid- and lower slope in this area.
