Palynomorphs have proven to be very valuable in correlating sediments of Neogene to Recent age from the New Jersey rise to the Atlantic Coastal Plain, primarily because calcareous microfossils are rare in these terrigenous sediments. Both marine and terrestrial palynomorphs are abundant in relatively cool, low salinity neritic environments, and preserve well in these sediments. Marine palynomorphs (dinocysts) allow correlation with deep sea environments, while terrestrial palynomorphs (pollen and spores) permit land-sea correlation. We report on data from the Ocean View and Bass River Boreholes, ODP Sites 1071, 1072, and 1073, and DSDP Site 604, and attempt to correlate these data with published data from the central North Atlantic, the New Jersey margin, the Atlantic Coastal Plain, and the northeastern United States. Palynological assemblages also provide insights into sediment transport and sea levels, and thus are ideal tools to test the role of glacioeustasy in continental margin architecture. The erosional unconformity generated during Oxygen Isotope Stage 12 had a strong impact on the architecture of the New Jersey margin, and has been identified as sequence boundary pp3(s). The relationship between glacioeustasy and other sequence boundaries on the New Jersey margin is not as straightforward, however. Sediment influx appears to be a very important component of the Neogene to Recent architecture of this margin.
