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 ...

The produced waters of oil deposits in Tomsk region: its use for iodine industrial production [PDF]

, 2016
In world practice, groundwater is the main raw material for iodine production. In the current geopolitical conditions, a significant part of the traditional areas of iodine production is located outside the Russian Federation.

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 ...

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 ...
