Marcell Experimental Forest

[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.

[3][4] Some notable research areas have been hydrology, nutrient and mercury cycling and behavior, and release of organic carbon and acidity.

The peatlands may be treeless or have tree cover and the forested bogs contain black spruce and tamarack.

[1] The climate is subhumid continental with moist warm summers and relatively dry, cold, and sunny winters including large diurnal and seasonal temperature fluctuations.

[1][5] This is a 10+ year, large scale Department of Energy sponsored experiment that is a collaboration between the US Forest Service Northern Research Station and Oak Ridge National Laboratory and involves 100+ scientists from around the world.
