We provide a backstripped Late Cretaceous sea-level record using these sequences, taking into account sediment loading, compaction, paleo-water depth, and basin subsidence. Here we show that sea-level changes were large (>25 m) and rapid (<<1 m.y.), strongly suggesting a glacioeustatic control of sea-level variations during the Late Cretaceous. The NJ Late Cretaceous sequence boundaries generally correspond in age with sea-level lowerings of Exxon Production Research (EPR), NW European and Russian sections, indicating a global cause, though previous EPR amplitudes are too large by a factor of 2. Oxygen isotopic data, a proxy for ice volume and paleotemperatures, are consistent with a glacioeustatic cause. Comparison of sea-level records with other changes in the geobiosphere (e.g., extinctions, adaptive radiations, ocean anoxic events, carbon isotopic variations) show that long-term (10-m.y.-scale) sea-level changes are associated with the general diversification of Mesozoic phytoplankton, but there is little correlation on the m.y.-scale.completedStratigraphyIsotope geochemistryadaptive radiationalkaline earth metalsanaerobic environmentAtlantic Coastal PlainbiostratigraphyC-13/C-12carbonCenozoiccompactionCretaceouseustacyextinctionisotope ratiosisotopesLeg 174AXMesozoicmetalsNeogeneNew JerseyO-18/O-16Ocean Drilling Programoxygenpaleo-oceanographypaleotemperaturephytoplanktonplanktonratesreconstructionsea-level changesSr-87/Sr-86stable isotopesstrontiumsubsidenceTertiaryUnited StatesUpper CretaceousvariationsEnglishgeoscientificInformation-75.3500-73.530038.300041.2100New Jersey
