Concentration‐Discharge Relations in the Critical Zone: Implications for Resolving Critical Zone Structure, Function, and Evolution

open access: yesWater Resources Research, 2017
Critical zone science seeks to develop mechanistic theories that describe critical zone structure, function, and long-term evolution. One postulate is that hydrogeochemical controls on critical zone evolution can be inferred from solute discharges ...

The Importance of Groundwater in Critical Zone Science

Groundwater, 2021
Abstract The critical zone (CZ)—from treetops to groundwater—is an increasingly studied part of the earth system, where scientists study interactions between water, air, rock, soil, and life. Groundwater is both a boundary and an essential store in this integrated system, but is often not well considered in part because of the ...

Methane cycling in the carbonate critical zone

Science of The Total Environment, 2023
The carbonate critical zone (CZ) is characterized by extensive groundwater-surface water exchange that leads to highly variable redox states of groundwater. Changes in redox condition may cause either production or consumption of methane (CH4), thereby providing an atmospheric source or sink of this important greenhouse gas.

Introduction to the Critical Zone

2015
Abstract The National Research Council (NRC, 2001, p. 2) defined the Critical Zone as “ the heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air and living organisms regulate the natural habitat and determine availability of life sustaining resources. ” From this original definition, many, now loosely

Carbonates in the Critical Zone

2023
Earth's Critical Zone (CZ), the near-surface layer where rock is weathered and landscapes co-evolve with life, is profoundly influenced by the type of underlying bedrock. Previous studies employing the CZ framework have focused primarily on landscapes dominated by silicate rocks.

Investigating the Root Zone Critical Interface in Intensively Managed Critical Zones

The Critical Zone (CZ) in the Midwestern United States has transformed from predominantly prairie landscapes to highly productive row-crop agriculture that requires intensive management such as tillage, tile drains and fertilizer inputs. The Critical Interfaces CZ Network (CINet) project focused on three critical interfaces that are important ...

Climate of the Critical Zone

2015
Abstract Climate variability, both in space and in time, has a significant impact on nearly every aspect of the Critical Zone. The primary focus of this chapter is on soil moisture because it is an important component of the water balance in the Critical Zone and it is a key parameter that influences land–atmosphere interactions in the climate system

Critical Zone Science

2018
My class used Water Balance of a Tree (Unit 5.1) to begin quantifying the fundamental pathways for water movement within a forest. The ultimate goal was to model transpiration of the redwood forest on the UC Santa Cruz campus.

Critical zones in desert fog

Proceedings of the 11th annual ACM symposium on User interface software and technology, 1998
In this paper, we introduce the problem of “desert fog,” a condition wherein a view of an information world contains no information on which to base navigational decisions. We present a set of view-based navigational aids that allow navigators to find their way through desert fog in multiscale electronic worlds.
