Simulating late Pliocene northern hemisphere climate with the LLN 2-D model [PDF]
, 1998 Deep-sea sediment records suggest Northern Hemisphere glaciation intensified at approximately 2.75 Ma. In this paper we simulate the fluctuations of the late Pliocene Northern Hemisphere ice-sheets volume using the LLN 2-D model, forced by the ...

The Dependence of Earth Milankovitch Cycles on Martian Mass [PDF]
The Milankovitch cycles of Earth result from gravitational interactions with other bodies in the solar system. These interactions lead to slow changes in the orbit and angular momentum vector of Earth, and correspondingly influence Earth’s climate ...

Energy Geoscience, 2023 Restoring the deposition velocity during evolution in basin analysis is an important aspect. The restoration of high-resolution deposition velocity—the deposition velocity over a short geological period—can improve the precision of basin analysis and ...

Milankovitch Period Uncertainties and Their Impact on Cyclostratigraphy [PDF]
, 2015 Astronomically calibrated cyclostratigraphy relies on correct matching of observed sedimentary cycles to predicted astronomical drivers such as eccentricity, obliquity and climate-precession. However the periods of these astronomical cycles, in the past,

Recognition of non-Milankovitch sea-level highstands at 185 and 343 thousand years ago from U-Th dating of Bahamas sediment [PDF]
, 2006 Thirty-one new bulk-sediment U-Th dates are presented, together with an improved δO stratigraphy, for ODP Site 1008A on the slopes of the Bahamas Banks. These ages supplement and extend those from previous studies and provide constraints on the timing of
