Abstract:

During Leg 1 of cruise ATLANTIS II-94, a multidisciplinary investigation of present-day sediment-current interactions was carried out on the insular rise south of Iceland. The principal objective was to study the relationships between relatively steady thermohaline flow, episodic turbidity current flow, and the types of sediments associated with these current systems. The northern Iceland Basin is an optimal site for studying these effects because of the well-developed deep thermohaline current system resulting from overflow from the Norwegian Sea, and the substantial imput of terrigenous Largely volcanogenic debris from the Iceland margin which has occurred since the post-glacial rise in sea level. In this report, we outline the regional setting, objectives, and scientific operations of the cruise, and present examples of typical seismic profiles and 3.5 kHz records from areas of particular importance. All station locations are tabulated, and satellite fixes are listed.
