On Time Scales of Intrinsic Oscillations in the Climate System

Entropy, 2021
Proxy temperature data records featuring local time series, regional averages from areas all around the globe, as well as global averages, are analyzed using the Slow Feature Analysis (SFA) method.

Benchmarking Multiple Methods for the Spectral Analysis of Seafloor Morphology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The influence of glacial sea‐level changes on the quasi‐periodic spacing of abyssal hills has remained controversial for over a decade. Spectral analyses of seafloor morphology have yielded contrasting conclusions regarding whether periodicities associated with orbital Milankovitch forcing are recorded in abyssal hill spacing, raising ...

Early Cretaceous Terrestrial Milankovitch Cycles in the Luanping Basin, North China and Time Constraints on Early Stage Jehol Biota Evolution

Frontiers in Earth Science, 2020
This research analyzes the cyclostratigraphy of the lacustrine Dabeigou Formation (DBG) of early Jehol Biota age (∼130–135 Ma) in the Luanping Basin, northern China.

Sedimentary facies and stacking patterns of fluvio‐deltaic and ‐estuarine deposits from the Palaeoarchean Moodies Group in the Stolzburg Syncline (Barberton Greenstone Belt, South Africa)

The Depositional Record, Volume 12, Issue 4, September 2026.
Drillcore BASE‐5B from the Stolzburg Syncline, Barberton Greenstone Belt, reveals a coarsening‐upward, river‐dominated fluvio‐deltaic succession transitioning upward to a fining‐upward, tide‐dominated‐estuarine succession. Abstract Investigating fluvio‐marine depositional environments from early geological times is of great importance, as they provide ...

Peritidal carbonate cycles induced by carbonate productivity variations: A conceptual model for an isolated Early Triassic greenhouse platform in South China

Journal of Palaeogeography, 2014
Eustasy has commonly been invoked to explain peritidal carbonate cyclicity, but is difficult to explain cycles formed in a greenhouse climate when eustasy is minimal.

Are Species Distribution Models That Use Climate Variables Suitable to Forecast the Changing Distribution of Freshwater Organisms?

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.

Testing the impact of stratigraphic uncertainty on spectral analyses of sedimentary series [PDF]

Climate of the Past, 2016
Spectral analysis is a key tool for identifying periodic patterns in sedimentary sequences, including astronomically related orbital signals. While most spectral analysis methods require equally spaced samples, this condition is rarely achieved either in

Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.

Seeing Through the Noise: Implications for Signal Preservation in Sediment Flux Time Series From Erosional Systems

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Allogenic forcing of sediment production generates sedimentary signals that we use to understand the past. These signals may be buffered or shredded by autogenic processes as they travel through sediment routing systems from source to sink. Studies on signal propagation tend to focus on either signal buffering by deterministic fluvial networks

Identification of Milankovitch Cycles and Their Sedimentary Responses in Fine-Grained Depositional Strata on the Southwestern Margin of the Songliao Basin

Applied Sciences
A series of fault depressions developed in the Kailu area on the southwestern margin of the Songliao Basin, where thick lacustrine fine-grained sedimentary rocks were widely deposited during the initial faulting stage in the Early Cretaceous.
