Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

A field experiment on the use of biogeotextiles for the conservation of sand-dunes of the Baltic coast in Lithuania

Hungarian Geographical Bulletin, 2012
Extreme damage was caused by wave and wind erosion on sand dunes on the Baltic coast near Palanga in Lithuania. Waves breached a wide ‘corridor’ or ‘blowout’ through the coastal sand dune. A progressively widening breached blowout developed.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Estimating Grain Sizes of Martian Dune Sand: A Freeware‐Based Methodology With Initial Results

Earth and Space Science
Grain sizes of Martian sand dunes are critical sedimentological data on sand provenance and transport pathways. Thermal inertia values are used to characterize the grain sizes of dune sand. Most early characterizations involved single dune fields. Recent

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute
