Mapping Arsenic Risks in the Ayeyarwady (Irrawaddy) Delta, Myanmar: Implications for Public Health

GeoHealth, Volume 9, Issue 11, November 2025.
Abstract The Ayeyarwady Delta in Myanmar, home to an estimated 12 million people, faces widespread arsenic contamination similar to other Asian deltas namely Bengal, Red River, and Mekong. Arsenic here primarily results from reductive dissolution of iron minerals in anoxic conditions driven by organic carbon. Here, we used digital elevation model (DEM)

Inferring End‐Members From Geoscience Data Using Simplex Projected Gradient Descent‐Archetypal Analysis

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract End‐member mixing analysis (EMMA) is widely used to analyze geoscience data for their end‐members and mixing proportions. Many traditional EMMA methods depend on known end‐members, which are sometimes uncertain or unknown. Unsupervised EMMA methods infer end‐members from data, but many existing ones don't strictly follow necessary constraints ...

Linking Surface Processes, Solute Generation, and CO2 Budgets Across Lithological and Land Cover Gradients in Rocky Mountain Watersheds

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract Chemical weathering in mountain critical zones controls river chemistry and regulates long‐term climate. Mountain landscapes contain diverse landforms created by geomorphic processes, including landslides, glacial moraines, and rock glaciers. These landforms generate unique flowpaths and water‐rock interactions that modify water chemistry as ...

Spatiotemporal Response and Phytopotential of Typha domingensis for Management of Aquatic Metal Pollution on the Central African Copperbelt

Ecology and Evolution, Volume 15, Issue 3, March 2025.
The study provides an eco‐friendly, nature‐based approach for biomonitoring and management of mining pollution to ensure aquatic ecosystem sustainability in sub‐Saharan Africa mining landscapes. We investigated the phytoindication and phytoremediation potential of Typha domingensis for the management of mining pollution in tropical lotic ecosystems ...

Hydrogeochemistry and isotope geochemistry of Velenje Basin groundwater

Geologija, 2016
The geochemical and isotopic composition of groundwater in the Velenje Basin, Slovenia, was investigated between the years 2014 to 2015 to identify the geochemical processes in the major aquifers (Pliocene and Triassic) and the water–rock interactions.

Improving Stream Solute Predictions With a Modified LSTM Model Incorporating Solute Interdependences and Hysteresis Patterns

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Surface runoff and infiltrated water en route to the stream interact with dynamic landscape properties, ranging from vegetation and microbial activities to soil and geological attributes. Stream solute concentrations are highly variable and interconnected due to these interactions, flow paths, and residence times, and often exhibit hysteresis ...

Chemical and Isotopic Characteristics of Hot Spring Water and Genesis Analysis Under the Constraint of Nappe Structure in the Midu Area, Dali Prefecture, Yunnan, China

Geofluids, Volume 2025, Issue 1, 2025.
The Midu Basin has a complex geological structure, active neotectonic movement, strong magmatic activity, and abundant geothermal resources, but the current research degree is low. Five representative hot springs in the Midu area were studied; the hydrochemistry and hydrogen and oxygen isotope characteristics of water samples were analyzed; and the ...
