Six Oligocene sequences and one earliest Miocene sequence were identified at Island Beach, Atlantic City, and Cape May, New Jersey, and correlated to the delta (super 18) O proxy of glacioeustasy and the eustatic record of Haq et al. by integrating lithostratigraphy, biostratigraphy, Sr isotopic stratigraphy, and magnetostratigraphy. Seven global delta (super 18) O increases are recognized by correlating delta (super 18) O records among deep-sea sites; four of these increases (Oi1, Oi2, Oi2b, and Mi1; 33.5, 30.3, 27.1, and 23.8, respectively) were recognized previously, and three (Oi1a, Oi1b, and Oi2a; 32.8, 31.7, 28.3 Ma, respectively) are new. These delta (super 18) O increases correlate well with Oligocene unconformities, indicating a glacioeustatic control on sequence boundaries. Except for an unconformity and glacioeustatic lowering at approximately 28.3 Ma, the New Jersey Oligocene sequences correlate well with the Haq et al. record, although we question the amplitudes of their eustatic record.
