Machine learning approach that combines multiple algorithms to improve predictive performance and robustness

Redox-stratified and temporally dynamic sediments in river corridors where biological processes mediate sulfur transformations

Microbial reduction of sulfate coupled to organic matter oxidation in anoxic environments resulting in formation of low solubility sulfide minerals

Process where trees shift their root water uptake from topsoil towards subsoil to sustain transpiration rates when shallow soil moisture declines

The cycling of iron between different chemical forms including soluble ferrous iron (Fe(II)) and ferric iron (Fe(III)) based on oxygen availability

Mathematical model describing sigmoidal population growth with carrying capacity constraints

Process where cations in solution exchange with cations adsorbed on mineral surfaces

Concentration-discharge pattern where solute concentrations remain relatively constant across flow conditions, indicated by C-Q slope near zero

Process of using large-scale climate model outputs to generate local or regional scale climate projections

Statistical approach to quantify proportional contributions of different water sources to mixed samples using tracer concentrations

Measure of the relative contribution of each predictor variable obtained by calculating mean decrease in mean square error

Spatial variations in oxidation-reduction conditions within floodplain environments that can form within microsites, along textural transitions, or along the capillary fringe

Process by which melting snow penetrates soil and triggers changes in microbial activity and nutrient cycling

The amount of water stored in soil and subsurface compartments that responds dynamically to hydrological inputs and outputs

The study of the complete set of RNA transcripts produced by the genome under specific circumstances

Formation of coordination complexes between Fe(II) ions and natural organic matter ligands

Part of quality management focused on providing confidence that quality requirements will be fulfilled

Mathematical equation describing water flow in partially saturated soils by relating volumetric soil water content to constitutive relations

The downward movement of water from surface water to groundwater, occurring through infiltration and percolation processes and declining under warming due to increased evapotranspiration
