Quasi-100 ky glacial-interglacial cycles triggered by subglacial burial carbon release [PDF]

Climate of the Past, 2007
A mechanism is proposed in which climate, carbon cycle and icesheets interact with each other to produce a feedback that can lead to quasi-100 ky glacial-interglacial cycles. A central process is the burial and preservation of organic carbon by icesheets

Diagenetic Self-Organization and Stochastic Resonance in a Model of Limestone-Marl Sequences

Geofluids, 2018
Banded patterns in limestone-marl sequences (“rhythmites”) form widespread sediments typical of shallow marine environments. They are characterized by alternations of limestone-rich layers and softer calcareous-clayey material (marl) extending over ...

Astronomical Orbital Cycle-Driven Coevolution of Paleoclimate and Sea Level with Sedimentary Response: A Case Study from the Upper Member of the Miocene Zhujiang Formation in the Enping Depression, South China Sea

Applied Sciences
This study focuses on the upper section of the Zhujiang Formation in the Enping Sag of the Zhujiangkou Basin in the South China Sea, investigating the mechanisms by which astronomical orbital cycles drive paleoclimate, sea-level fluctuations, and ...

The Dependence of Earth Milankovitch Cycles on Martian Mass

Publications of the Astronomical Society of the Pacific
Abstract 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 evolution. Several studies have shown that Mars may play a

Global Carbon Cycle Recorded in the Deep-sea Sediments and Milankovitch Cycle.

Journal of Geography (Chigaku Zasshi), 1995
Several hundred years of astronomical observations have left no doubt that the Earth's orbit is subject to cyclic variations. While the annual energy receipt of solar radiation over the Earth as a whole is not change, the distribution of this energy, by latitude and by season, is affected by three parameters: an obliquity cycle of 41kyr, an ...
