| Abstract: | Examination of 38 sediment cores, bottom photographs, 7,000 km of 3.5 kHz reflection profiles and other seismic data from
the southern part of the Nares Abyssal Plain suggests that complex sedimentary patterns and high sedimentation rates can be
largely attributed to effects of a deep boundary current flowing eastward along the north flank of the Greater Antilles Outer
Ridge. It is concluded that the areal dispersal pattern of turbidites on the plain results mainly from Quaternary climatically-induced
fluctuations of the boundary current intensity. |
