The complex dynamics of the seasonal component of USA's surface temperature [PDF]

Atmospheric Chemistry and Physics, 2010
The dynamics of the climate system has been investigated by analyzing the complex seasonal oscillation of monthly averaged temperatures recorded at 1167 stations covering the whole USA.

Paleotemperature evolution and its driving mechanism during the formation of limestone-marl alternations in first member of Middle Permian Maokou Formation in Sichuan Basin

Shiyou shiyan dizhi, 2023
From the Late Carboniferous to the end of Middle Permian, the most intense glacial event in history of Phanerozoic occurred and it is also the last transition period from icehouse stage to greenhouse stage in geological history.

Milankovitch cycles and the astronomical time scale of the Zhujiang Formation in the Baiyun Sag, Pearl River Mouth Basin, China

Open Geosciences, 2022
The Zhujiang Formation in the Baiyun Sag, Pearl River Mouth Basin, China, is formed primarily in a deep-water continental slope environment. Its chronostratigraphic framework is based on biostratigraphy and sequence stratigraphy, and its geological ...

Genetic mechanism of multi-scale sedimentary cycles and their impacts on shale-oil distribution in Permian Lucaogou Formation, Jimusar Sag, Junggar Basin

Unconventional Resources, 2023
Complex lithofacies of Lucaogou Formation in Jimusar Sag promote strong heterogeneity of oil distribution in fine grained sedimentary rocks. It is of great significance to define the formation mechanism of fine-grained sedimentary rocks for favorable ...

A Spreading‐Rate Dependence for Periodic Signals Embedded in Otherwise Aperiodic Abyssal Hills

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract I present evidence, through an empirical pre‐whitening analysis, that periodic signals are embedded in otherwise aperiodic abyssal hills across paleo‐spreading rates ranging from 1 to 9 cm/yr (half rate). Data are comprised of archival trackline and multibeam bathymetry profiles in north and south Atlantic Oceans, Pacific‐Antarctic Ridge ...

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Temperature response of Mars to Milankovitch cycles [PDF]

Geophysical Research Letters, 2008
On Mars annual mean surface temperature near ±60° latitude varies predominately with precession and is not closely related to annual mean insolation. Based on the last few million years of orbital history, the precession cycle dominates in a narrow latitude range 54°–65°, in which the margins of the two ice‐rich permafrost layers in each hemisphere ...

Milankovitch cycles of terrestrial planets in binary star systems [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
The habitability of planets in binary star systems depends not only on the radiation environment created by the two stars, but also on the perturbations to planetary orbits and rotation produced by the gravitational field of the binary and neighbouring planets.
