|a Earth’s long-term sea-level history is characterized by widespread continental flooding in the
Cretaceous period (~145 to 65 million years ago), followed by gradual regression of inland seas.
However, published estimates of the Late Cretaceous sea-level high differ by half an order of
magnitude, from ~40 to ~250 meters above the present level. The low estimate is based on
the stratigraphy of the New Jersey margin. By assimilating marine geophysical data into
reconstructions of ancient ocean basins, we model a Late Cretaceous sea level that is 170 (85 to
270) meters higher than it is today. We use a mantle convection model to suggest that New Jersey
subsided by 105 to 180 meters in the past 70 million years because of North America’s westward
passage over the subducted Farallon plate. This mechanism reconciles New Jersey margin–based
sea-level estimates with ocean basin reconstructions. |
