Long-Term Sea-Level Fluctuations Driven by Ocean Basin Dynamics
R. Dietmar Muller,1* Maria Sdrolias,1 Carmen Gaina,2 Bernhard Steinberger,2
Christian Heine1
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.
