Marcell_Experimental_Forest
Marcell Experimental Forest (MEF) is a 1,140 ha long-term ecosystem research site operated by the Northern Research Station of the U.S. Forest Service.[1] It is located 40 km north of Grand Rapids, Minnesota within the Chippewa National Forest and was formally established in 1962 to study the ecology and hydrology of peatland watersheds.[2][1] There are six experimental watersheds each of which consist of an upland portion, a peatland, and an outlet stream.[3] The range of these six watersheds provide a variety of hydrological environments to study.[3] Climatic and hydrologic data have been continuously monitored since 1961.[3][4] Some notable research areas have been hydrology, nutrient and mercury cycling and behavior, and release of organic carbon and acidity.[3]
MEF is the longest running National Atmospheric Deposition Program (NADP) site in the nation.[1]
