A series of single channel seismic reflection profiles were collected by the U.S. Geological Survey aboard the R.V. FAY from August 10, 1976 through September 7, 1976 during cruises FAY 20 and FAY 21. The chief scientist was, Dr. Kim D. Klitgord, U.S. Geological Survey, Woods Hole, MA 02543. The profiles are located on the slope and rise between Cape Hatteras and the New England Seamounts and include 10 profiles which are roughly perpendicular to the continental margin and 4 long profiles which are parallel to the margin. Single channel seismic reflection profiles are available on all of the profiles indicated on the accompanying figure with the exception of FAY 21-5 and FAY 21-10. Approximately 5,850 km of seismic reflection data were collected. These profiles complement and extend to the northeast the grid of seismic profiles collected on the cruise FAY 19 (open file report#?). The seismic profiles collected on cruises FAY 19, FAY 20 and FAY 21 tie in the U.S. Geological Survey grid of multichannel seismic reflection profiles and the IPOD/USGS multichannel profile on the continental shelf, slope and upper rise with the DSDP holes #105, 106 and 388.
