A synthesis of 50 years of research on hydrology and biogeochemistry of peatland watersheds at the Marcell Experimental Forest, this book covers the project's history, accomplishments, and future directions. It examines the establishment of the MEF, the value of long-term monitoring, the paleo-history of the MEF landscape, the effects of forest management on water and chemical fluxes, the physical and chemical properties of upland and peatland soils, and the cycling of mercury. Figures, photographs, and tables depict concepts and findings within the book.
