Abstract

Site U1607 (proposed Site MB-07B), the easternmost site in the Expedition 400 site transect, was cored at 74°29.5499′N, 60°34.9900′W at 739 meters below sea level (mbsl) on the middle shelf (Figure F1). Extensive seismic and limited borehole data indicate that this site captures Megaunits C, D1, and D2, interpreted as a middle–late Miocene sediment drift that overlies a succession of mainly hemipelagic strata, possibly of early Miocene to Oligocene age (Knutz et al., 2022b) (Figures F2, F3). Accordingly, Site U1607 may capture the time period from 6 to 30 Ma.
