Rising atmospheric CO <sub>2</sub> concentrations: the overlooked factor promoting SW Iberian Forest development across the LGM and the last deglaciation? Open
Across the last deglaciation, the atmospheric CO2 concentration (CO2) increased substantially from ∼ 180 to ∼ 280 ppm, yet its impact on vegetation dynamics across this major climatic transition remains insufficiently understood. In partic…

Be evidence for extensive, low-elevation Late Pleistocene glaciation in far eastern (Arunachal) Himalayas - timing and palaeoclimate reconstruction   Open
The glacial history of the eastern Himalayas has remained undocumented compared to its western and central regions. In this study, we present 63 Be-10 exposure ages from glacial deposits in the Dri Valley, situated at the eastern extremity…

Rising atmospheric CO <sub>2</sub> concentrations: the overlooked factor promoting SW Iberian Forest development across the LGM and the last deglaciation? Open
Across the last deglaciation, the global atmospheric concentration of carbon dioxide (pCO2) increased from ~180 to ~280 ppm. However, the impact of pCO2 changes on vegetation across the last deglaciation remains poorly understood. Under fu…

Probing sediment burial age, provenance and geomorphic processes in dryland dunes and lake shorelines using portable luminescence data Open
Luminescence signals from portable optically-stimulated luminescence readers (POSL or port-OSL) can provide expedient insights into sample relative age, and under certain conditions can be simplistically calibrated against existing lumines…

Holocene linear dune accumulation in the western Thar desert, India.  Open
The densely populated Thar Desert in the northwestern part of the Indian subcontinent contains a complex spatial pattern of now vegetated dune morphologies. There is a growing dataset of luminescence ages that demonstrates a dominance of H…

S.A.N.D.S. - Surface Archaeology on the Namib Desert Surface.  Open
The hyper-arid Namib Sand Sea (NSS) represents a significant challenge to human occupation, yet, despite these challenges, Early Stone Age (ESA) and Middle Stone Age (MSA) tools are found across this landscape. Whilst surface scatters are …

Revisiting the Acheulean at Namib IV in the Namib Desert, Namibia Open
Namib IV (S23° 44.829’, E14° 19.720’) is frequently cited, as it is one of few Earlier Stone Age sites in the Sand Sea of the Namib Desert. The site was first investigated in 1978 by Myra Shackley, who described 582 artifacts on the surfac…

Reconstructing rainfall using dryland dunes: Assessing the suitability of the southern Kalahari for unsaturated zone hydrostratigraphies Open
Time-series of dryland rainfall over 100–1000 s of years are scarce but are needed to underpin improved predictions under future climate change. Dryland sand dunes are established Quaternary geomorphic archives, which also contain pore moi…

Fluvial-aeolian interactions and sand provenance in large African Sand Seas (Sahara and Kalahari) Open
<p>Deserts are virtually the largest exposed sand depository on earth and their interaction with the river network may unveil information of present and past routing systems. Provenance studies of Sahara, Kalahari Deserts intend to a…

Reconstructing rainfall in sandy drylands of southern Africa: exploring the potential of the chloride mass balance hydrostratigraphy approach in Kalahari sand dunes.  Open
<p>Sand dunes sediments are a commonly used archive for palaeoenvironmental reconstruction, with chronologies for their accumulation rates, and migration rates, used in a large number of palaeoenvironmental reconstructions across glo…

Dryland dunes and other dryland environmental archives as proxies for Late Quaternary stratigraphy and environmental and climate change in southern Africa Open
The Namib Desert and the Kalahari constitute the drylands of southern Africa, with the current relatively humid portions of the latter having experienced periodically drier conditions during the Late Quaternary. This study explores the ran…

Former humid phases in the southwestern Arabian peninsula: climatic and environmental implications of the tufa record over the last 250 ka from the Harrat Al Birk, Saudi Arabia.   Open
<p>Little is known about the tufa deposits within the volcanic Harrats of western Saudi Arabia. This research aims to characterise the fossil tufa system and examine its utility as a palaeoenvironmental archive. This requires us to u…
