Headwater catchments are the fundamental units that connect the land to the ocean.
Hydrological flow and biogeochemical processes are intricately coupled, yet their respective …

Significant advances in understanding and predicting freshwater algal bloom dynamics
have emerged in response to both increased occurrence and financial burden of nuisance …

Understanding concentration‐discharge (C‐Q) relationships are essential for predicting
chemical weathering and biogeochemical cycling under changing climate and …

Lateral carbon flux through river networks is an important and poorly understood component
of the global carbon budget. This work investigates how temperature and hydrology control …

How does hillslope structure (eg, hillslope shape and permeability variation) regulate its
hydro‐geochemical functioning (flow paths, solute export, chemical weathering)? Numerical …

Concentration-discharge relationships are a key tool for understanding the sources and
transport of material from watersheds to fluvial networks. Storm events in particular provide …

Clay weathering in shales is an important component of the global Li budget because Li is
mobilized from Li-rich clay minerals and shale represents about one quarter of the exposed …

Mounting evidence suggests ecosystem changes that alter subsurface water fluxes and
carbon dioxide concentrations in carbonate terrains may drive measurable changes in …

Core Ideas Studying the critical zone requires targeted research on water, energy, gas,
solutes, and sediments. The SSHCZO targets a 165‐km2 watershed on sedimentary rocks in …

The concentrations of weathering‐derived solutes in rivers and their covariance with
discharge are thought to reflect reactive‐transport processes in hillslopes and to reveal the …
