Orbital-and millennial-scale changes in the hydrologic cycle and vegetation in the western African Sahel: insights from individual plant wax δD and δ13C
To reconstruct variability of the West African monsoon and associated vegetation changes
on precessional and millennial time scales, we analyzed a marine sediment core from the …

Vegetation change, goats, and religion: a 2000-year history of land use in southern Morocco
Understanding past human–climate–environment interactions is essential for assessing the
vulnerability of landscapes and ecosystems to future climate change. This is particularly …

Twenty years of XRF core scanning marine sediments: what do geochemical proxies tell us?
RG Rothwell, I Croudace - Micro-XRF Studies of Sediment Cores …, 2015 - Springer
XRF core scanners, with their rapid and non-destructive analytical capability, have now
been used for two decades in the analysis of marine sediments. Initially they were used to …

Distribution of major elements in Atlantic surface sediments (36 N–49 S): Imprint of terrigenous input and continental weathering
Numerous studies use major element concentrations measured on continental margin
sediments to reconstruct terrestrial climate variations. The choice and interpretation of …

The magnitude, timing and abruptness of changes in North African dust deposition over the last 20,000 yr
Reconstructions of eolian dust accumulation in northwest African margin sediments provide
important continuous records of past changes in atmospheric circulation and aridity in the …

Astronomically controlled aridity in the Sahara since at least 11 million years ago
The Sahara is the largest hot desert on Earth. Yet the timing of its inception and its response
to climatic forcing is debated, leading to uncertainty over the causes and consequences of …

Increase in African dust flux at the onset of commercial agriculture in the Sahel region
Abstract The Sahara Desert is the largest source of mineral dust in the world. Emissions of
African dust increased sharply in the early 1970s (ref.), a change that has been attributed …

Sahel megadroughts triggered by glacial slowdowns of Atlantic meridional overturning
The influence of the large‐scale ocean circulation on Sahel rainfall is elusive because of the
shortness of the observational record. We reconstructed the history of eolian and fluvial …
