Does Eolian Flux to the Northwest Pacific Ocean Reflect Persistent Asian Interior Aridity on Orbital Timescales?

Geophysical Research Letters
Northwest Pacific sedimentary eolian dust flux records have long been used to make direct inferences about Asian interior aridity. However, factors other than aridity can impact dust production rate.

Late Pleistocene Climate and Dust Source From the Mobarakabad Loess–Paleosol Sequence, Northern Foothills of the Alborz Mountains, Northern Iran

Frontiers in Earth Science, 2021
Paleoclimatic investigation of loess-paleosol sequences from northern Iran is important for understanding past changes in a region highly sensitive to shifts in precipitation, and along potential routes of past human migration.

Impact of Sahelian Climate Variables on Solar Photovoltaic Output

Energy Science &Engineering, EarlyView.
ABSTRACT Solar photovoltaic (PV) energy is a critical pathway for advancing the energy transition in the Sahel. However, PV module performance in this region is strongly constrained by extreme climatic conditions. This study investigates the effects of (1) wind speed, (2) relative humidity, (3) temperature, (4) dust deposition, and (5) solar irradiance

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Dynamic Coupling Between Intensified Physical Erosion and Asian Dust Activity Under Late Cenozoic Global Cooling

Geophysical Research Letters
Distinguishing the independent contributions of tectonic denudation and climate‐driven erosion on the production and supply of clastic materials of Chinese eolian deposits is important in understanding the dynamic links between global climate changes ...

Long‐Term Operation of Photovoltaic Power Stations Promotes Soil Carbon Sequestration but Induces Stoichiometric C:N:P Imbalance in Desert Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Soil carbon‐nitrogen‐phosphorus (C:N:P) stoichiometry governs nutrient cycling and carbon sequestration in desert ecosystems, yet how large‐scale photovoltaic (PV) deployment, a cornerstone of global carbon neutrality, shifts these stoichiometric balances and whether such shifts enhance or degrade long‐term land function remain unresolved over

Role of eolian dust deposits in landscape development and soil degradation in southeastern Australia [PDF]

, 2016
Eolian dust plays a significant role in landscape development and landscape processes in Australia. Thin dust mantles, rarely exceeding 3 m in thickness, have been identified across many parts of the Australian landscape, particularly in southeastern ...

Unmixing biogenic and terrigenous magnetic mineral components in red clay of the Pacific Ocean using principal component analyses of first-order reversal curve diagrams and paleoenvironmental implications

Earth, Planets and Space, 2020
Red clay widely occupies the seafloor of pelagic environments in middle latitudes, and potentially preserves long paleoceanographic records. We conducted a rock-magnetic study of Pacific Ocean red clay to elucidate paleoenvironmental changes.
