Antarctic Peninsula Site 1103 (Ocean Drilling Program [ODP] Leg 178) was part of a transect drilled along a shallow progradational lobe of the continental shelf, off Anvers Island (Barker, Camerlenghi, Acton, et al., 1999). The recovered sedimentary facies record deposition of debris flows and poorly sorted turbidites on an active glacially influenced slope. Shipboard biostratigraphic analyses of the deepest drilled glacial sediments (Sequence Group S3) provided poor age assignments of pre-Pliocene, possibly late Miocene age (Shipboard Scientific Party, 1999).
