The structure of the critical zone (CZ) is a result of tectonic, lithogenic, and climatic forcings that shape the landscape across geologic time scales. The CZ structure can be probed to measure contemporary rates of regolith production and hillslope evolution, and its fluids and solids can be sampled to determine how structure affects CZ function as a living filter for hydrologic and biogeochemical cycles. Substantial uncertainty remains regarding how variability in climate and lithology… 

Geochemical evolution of the Critical Zone across variable time scales informs concentration‐discharge relationships: Jemez River Basin Critical Zone Observatory

This study investigates the influence of water, carbon, and energy fluxes on solute production and transport through the Jemez Critical Zone (CZ) and impacts on C‐Q relationships over variable

Climatic and landscape controls on water transit times and silicate mineral weathering in the critical zone

The critical zone (CZ) can be conceptualized as an open system reactor that is continually transforming energy and water fluxes into an internal structural organization and dissipative products. In

Resolving Deep Critical Zone Architecture in Complex Volcanic Terrain

Critical zone (CZ) structure, including the spatial distribution of minerals, elements, and fluid‐filled pores, evolves on geologic time scales resulting from both top‐down climatic forcing and

Coupled transport, fractionation and stabilization of dissolved organic matter and rare earth elements in the critical zone

It is important to understand the processes that influence the critical zone (CZ) evolution to ensure its sustainability. This thesis reports on laboratory and field experiments designed to measure

Critical Zone Science in the Anthropocene: Opportunities for biogeographic and ecological theory and praxis to drive earth science integration

Critical Zone Science (CZS) represents a powerful confluence of research agendas, tools, and techniques for examining the complex interactions between biotic and abiotic factors located at the

Controlled Experiments of Hillslope Coevolution at the Biosphere 2 Landscape Evolution Observatory: Toward Prediction of Coupled Hydrological, Biogeochemical, and Ecological Change

Understanding the process interactions and feedbacks among water, porous geological media, microbes, and vascular plants is crucial for improving predictions of the response of Earth’s critical zone

Quantifying Topographic and Vegetation Effects on the Transfer of Energy and Mass to the Critical Zone

Critical zone evolution, structure, and function are driven by energy and mass fluxes into and through the terrestrial subsurface. We have developed an approach to quantifying the effective energy



An open system framework for integrating critical zone structure and function

The “critical zone” includes the coupled earth surface systems of vegetation, regolith and groundwater that are essential to sustaining life on the planet. The function of this zone is the result of

Linking River Channel Form and Process: Time, Space and Causality Revisited

Fluvial geomorphology has witnessed a continuing reduction in the time- and space-scales of research, with increasing emphasis on the dynamics of small site-specific river reaches. This shift can be

Interactions Between Biogeochemistry and Hydrologic Systems

Here we review the fundamental interactions between hydrology and the cycling of carbon (C) and nitrogen (N) in terrestrial and stream ecosystems. We organize this review around five commonly studied

Quantifying the climatic and tectonic controls on hillslope steepness and erosion rate

Hillslopes in humid regions are typically convex to concave in profile and have a relatively thick, continuous regolith cover. Conversely, hillslopes in arid regions are typically cliff-dominated and

The illusion of diffusion: Field evidence for depth-dependent sediment transport

Soil-covered upland landscapes are common in much of the habitable world, and our understanding of their evolution as a function of different climatic, tectonic, and geologic regimes is important

The future of hydrology: An evolving science for a changing world

For a long-term initiative to address the regional implications of environmental change, hydrologists must become both synthesists and analysts, understanding the functioning of individual system components, while operating firmly within a well-designed hypothesis testing framework.

Tectonic and lithologic controls on bedrock channel profiles and processes in coastal California

[1] Recent theoretical models suggest that topographic characteristics of bedrock channels are products of interactions among tectonics, substrate resistance, and the climatically modulated erosive

Strong climate and tectonic control on plagioclase weathering in granitic terrain

On the role of aspect to quantify water transit times in small mountainous catchments

In the current empirical study, we provide evidence about how the hydrologic responses of small mountain catchments are related to aspect (slope direction and exposure) at Redondo Peak, located in
