Eccentricity forcing
WebFeb 9, 2015 · Earth’s long orbital eccentricity of 405 ky is considered unchanged over geological time, representing the metronome of astronomical forcing . Accepting this, our longest period from the Xiamaling Formation, at 305 ± 65 ky, is close to the orbital long eccentricity cycle. In our view, this similarity in period length is not a coincidence.

WebAug 5, 1997 · Deep-ocean carbon chemistry was clearly modulated by orbital forcing in a climate without large Northern Hemisphere ice sheets. Carbonate content of equatorial Pacific sediments fluctuated at a dominant period of 400 kyr in late Miocene times , another indication of a long history of eccentricity pacing of deep-ocean carbonate dissolution.
WebMar 1, 2024 · The expression of precession is apparently weak in the CENOGRID composite record, despite the dominant eccentricity forcing, likely owing to the long residence time of carbon in the oceans ... WebThe combined effect of precession with eccentricity is that proximity to the Sun occurs during different astronomical seasons. Milankovitch studied changes in these movements of the Earth, which alter the amount and …
WebFeb 1, 1997 · Milankovitch theory—that climate is controlled by variations in the Earth's orbital parameters—has gained wide acceptance for its ability to account for two climate cycles: a 23-kyr cycle that is phase-locked to the precession-driven insolation cycle, and a 41-kyr cycle that is phase-locked to the obliquity-driven insolation cycle1–6.
