Biogeochemistry of the critical zone

Biogeochemistry of the critical zone / Adam S. Wymore, Wendy H. Yang, Whendee L. Silver, William H. McDowell, Jon Chorover, editors.

This book highlights recent advances in the discipline of biogeochemistry that have directly resulted from the development of critical zone (CZ) science. The earth's critical zone (CZ) is defined from the weathering front and lowest extent of freely circulating groundwater up through the regoli...
