Effects of additive noise on the stability of glacial cycles

, 2016
It is well acknowledged that the sequence of glacial-interglacial cycles is paced by the astronomical forcing. However, how much is the sequence robust against natural fluctuations associated, for example, with the chaotic motions of atmosphere and ...

Geographic variability in dust and temperature in climate scaling regimes over the Last Glacial Cycle [PDF]

Climate of the Past
Temperature and mineral dust records serve as valuable palaeoclimatic indicators for studying atmospheric variability across different temporal scales. In this study, we employed Haar fluctuations to analyse global spatiotemporal atmospheric variability ...

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 ...

Science support for the Earth radiation budget sensor on the Nimbus-7 spacecraft [PDF]

Experimental data supporting the Earth radiation budget sensor on the Nimbus 7 Satellite is given. The data deals with the empirical relations between radiative flux, cloudiness, and other meteorological parameters; response of a zonal climate ice sheet ...

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 ...

Milankovitch cycles in Banded Iron Formations

, 2022
The astronomical theory of climate change resulting from quasi-periodic variations in the Earth’s orbit and spin axis (Milankovitch forcing) is now widely accepted for the Phanerozoic, the most recent ~0.5 billion years of Earth history. However, much older, Precambrian intervals remain largely unexplored.
