✦ Synopsis
High-resolution seismic reflection profiles (ϳ1-5 m resolution), including Geopulse, Uniboom, minisparker, small air gun, and water gun sources, are used to trace the d 18 O stage 5 portion of the outcropping Cape May Formation across the shelf to the continental slope. The d 18 O stage 5/6 boundary identified at Ocean Drilling Project (ODP) Site 903 on the continental slope anchors the onshore-offshore seismic correlations. Above the d 18 O stage 5 sequence, there are distinguishable lowstand systems tracts (LST), transgressive systems tracts (TST) and highstand systems tracts (HST) that correlate with d 18 O stages 4 through 1. Atlantic Margin Coring Project (AMCOR) holes 6009, 6010, 6011, 6020, and 6021C provide age and paleoenvironmental indicators that agree with these correlations. The sub-arctic paleoenvironmental indicators in sequences of d 18 O stage 3 agree with the cooler temperatures and lower sea-level highstands of that time. Thicker d 18 O stage 3 and 4 sequences are preserved in the Paleo-Hudson River incised valley across the shelf. The expanded ice sheets during stage d 18 O 3 compared to d 18 O stages 1 and 5 probably increased sediment discharge in the Hudson River drainage system.
