Abstract
High-resolution seismic reflection profiles (similar to 1-5 m resolution), including Geopulse(TM), Uniboom(TM), minisparker, small air gun, and water gun sources, are used to trace the delta(18)O Stage 5 portion of the outcro pping Cape May Formation across the shelf to the continental slope. The del ta(18)O stage 5/6 boundary identified at Ocean Drilling Project (ODP) Site 903 on the continental slope anchors the onshore-offshore seismic correlati ons. Above the delta(18)O stage 5 sequence, there are distinguishable lowst and systems tracts (LST), transgressive systems tracts (TST) and highstand systems tracts (HST) that correlate with delta(18)O stages 4 through 1. Atl antic Margin Goring Project (AMCOR) holes 6009, 6010, 6011, 6020, and 6021C provide age and paleoenvironmental indicators that agree with these correl ations. The sub-arctic paleoenvironmental indicators in sequences of delta( 18)O stage 3 agree with the cooler temperatures and lower sea-level highsta nds of that time. Thicker delta(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 delta(18)O 3 compared to delta(18)O stages 1 and 5 pro bably increased sediment discharge in the Hudson River drainage system. (C) 2000 Elsevier Science B.V.
