Heterogenous Late Holocene Climate in the Eastern Mediterranean—The Kocain Cave Record From SW Turkey

Geophysical Research Letters, 2021
Palaeoclimate variability must be constrained to predict the nature and impacts of future climate change in the Eastern Mediterranean. Here, we present a late Holocene high‐resolution multiproxy data set from Kocain Cave, the first of its kind from SW ...

Brief communication: Reduced bandwidth improves the depth limit of the radar coherence method for detecting ice crystal fabric asymmetry [PDF]

The Cryosphere
Ice crystal orientation fabric strongly affects the viscous deformation of glacier ice. A popular technique to investigate ice fabric is radar polarimetry, often analysed using the coherence method.

Bayesian Palaeoclimate Reconstruction [PDF]

Journal of the Royal Statistical Society Series A: Statistics in Society, 2006
SummaryWe consider the problem of reconstructing prehistoric climates by using fossil data that have been extracted from lake sediment cores. Such reconstructions promise to provide one of the few ways to validate modern models of climate change. A hierarchical Bayesian modelling approach is presented and its use, inversely, is demonstrated in a ...

Palaeovegetation and palaeoclimate changes across the Triassic–Jurassic transition in the Sichuan Basin, China

, 2020
The Triassic–Jurassic transition interval is marked by enhanced biotic turnover rates in both marine and terrestrial realms. However, limited data from Asia hampers the understanding of global ecosystem response to the end-Triassic mass extinction event.

Decoupling of δ¹⁸O from surface temperature in Antarctica in an ensemble of historical simulations [PDF]

Climate of the Past
Stable water isotopes recorded in Antarctic ice cores have traditionally been used to infer past surface air temperatures (SATs). During the historical period (1850 onward), observational data and good-quality ice core records overlap, yielding an ...

Construction of a deltaic strandplain during the Roman period in the Tavoliere di Puglia plain and palaeoclimatic implications

Frontiers in Earth Science, 2023
In response to the accidental exhumation of three ancient trees by farmers, we conducted a multidisciplinary study based on the stratigraphic analysis of boreholes, carbon-14 dating, aerial photo interpretation, and analysis of palaeobotanical and ...

Radiocarbon evidence for enhanced respired carbon storage in the Atlantic at the Last Glacial Maximum

Nature Communications, 2016
The Atlantic Ocean overturning circulation and its impact on respired carbon storage during glacial periods remains a mystery. Here, the authors combine radiocarbon and stable carbon isotope data from the Brazil and Iberian Margins to investigate ocean ...

Radiocarbon constraints on the glacial ocean circulation and its impact on atmospheric CO2

Nature Communications, 2017
Establishing the efficiency of the biological carbon pump is needed to constrain the impact of ocean circulation on the carbon cycle. Here, the authors compile a global array of ocean–atmosphere radiocarbon disequilibrium estimates and evaluate the ...
