Earth's critical zone (original) (raw)
Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources” (National Research Council, 2001). The Critical Zone, surface and near-surface environment, sustains nearly all terrestrial life. The critical zone is studied at Critical Zone Observatories, where multiple scientific communities study various aspects of the critical zone that can lead to synthesized understanding of complex systems.

| dbo:abstract | Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources” (National Research Council, 2001). The Critical Zone, surface and near-surface environment, sustains nearly all terrestrial life. The critical zone is an interdisciplinary field of research exploring the interactions among the land surface, vegetation, and water bodies, and extends through the pedosphere, unsaturated vadose zone, and saturated groundwater zone. Critical Zone science is the integration of Earth surface processes (such as landscape evolution, weathering, hydrology, geochemistry, and ecology) at multiple spatial and temporal scales and across anthropogenic gradients. These processes impact mass and energy exchange necessary for biomass productivity, chemical cycling, and water storage. The critical zone is studied at Critical Zone Observatories, where multiple scientific communities study various aspects of the critical zone that can lead to synthesized understanding of complex systems. (en) La zone critique est l'environnement terrestre qui s'étend de l'atmosphère, jusqu'aux roches non altérées. Elle englobe la basse atmosphère, la pédosphère, la zone vadose, les nappes d'eau souterraine et les roches altérées. C'est « l'environnement de proche-surface hétérogène dans lequel des interactions complexes entre la roche, le sol, l'eau, l'air et les organismes vivants régulent l'habitat naturel et déterminent la disponibilité des ressources vitales » (National Research Council, 2001). La zone critique abrite presque toute la vie continentale, dont l'humanité. La science de la zone critique est un champ de recherche interdisciplinaire explorant les interactions entre ses composantes : l'atmosphère, les roches, la biosphère, l'eau, etc. Elle regroupe les processus de surface de la Terre (tels que l'évolution du paysage, l'altération, l'hydrologie, la géochimie et l'écologie) à plusieurs échelles spatiales et temporelles et prend également en compte des facteurs anthropiques. Ces processus ont un effet sur les échanges de masse et d'énergie nécessaires à la productivité de la biomasse et aux cycles biogéochimiques et hydrologique. Les sont des territoires où des paramètres de l'environnement sont mesurés par différentes disciplines. Ces observatoires regroupent les communautés scientifiques et servent d'appui pour construire une compréhension de la zone critique en tant que système complexe. (fr) |
