Recent studies have focused on the Iridium anomaly in several New Jersey coastal plain outcrops and coreholes (Miller et al., 2010; Esmeray-Senlet, 2015 Ph.D. thesis) and the recovery of planktonic foraminifera and carbon cycle from mass extinction (Esmeray-Senlet et al., 2015). Our data from New Jersey and the deep sea indicate reduced export productivity consistent with the Living Oceans hypothesis, though other studies indicate zones of continued export productivity, prompting us to coin the term Heterogeneous Oceans (Esmeray-Senlet et al., 2015). Ir is associated with the mass extinction event in most sections, though it appears to have migrated downsection at Bass River, and Tighe Park. We continue to explore the relationship between Deccan Trap volcanism, impact, and the mass extinction.
