Abstract

Site U1603 (proposed Site MB-23A) is located at 72°59.04′N, 62°58.83′W in Baffin Bay at 1801 meters below sea level (mbsl), below a protrusion of the northwest Greenland margin shaped by the Melville Bugt Trough Mouth Fan (TMF) (Figure F1). The site targets an expanded drift-channel succession situated on the lower slope between two paleo–ice sheet outlets that represent major drainage routes for the northern Greenland ice sheet (NGrIS) into Baffin Bay (Knutz et al., 2019; Newton et al., 2017, 2021). The drilling strategy was to core a continuous high-resolution record of ice-ocean processes spanning the early late Pleistocene.
