Figure F3. Comparison of the ages of the Miocene sequence from the Bethany Beach borehole with the ages of sequences identified in New Jersey. Cross hatched = uncertain ages. Also shown is the benthic foraminifer oxygen isotopic record for Atlantic deep-sea sites (modified after Miller et al., 1997). Mi events are major isotopic increases that are inferred to correlate with ice growth events on Antarctica; arrows are placed at inflection points. Timescale is after Berggren et al. (1995).
