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 ...

Reservoir heterogeneity in deep marine-continental transitional shales: the role of lithofacies and quality in the coal-bearing longtan formation, central Sichuan basin

Frontiers in Earth Science
Compared with marine shale formations, marine-terrestrial transitional shales exhibit rapid lithofacies changes. This poses significant challenges for the classification of shale lithofacies and the study of their characteristics.

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

River Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.

Hydrological dynamics and morphological physiognomies of Dzüdza River, Nagaland, India: A Geographical Information System‐based quantification of drainage morphometry

River, EarlyView.
Abstract The assessment of the morphometric characteristics of the Dzüdza River basin in Nagaland has been critically important for hydrological analysis, flood risk assessment, soil erosion evaluation, and sustainable regional development, owing to its strategic location on the northern fringes of the Himalayas and flanked by hills to the east.

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...
