Marcell Experimental Forest biweekly bog frost depth, 1985 - ongoing

This data publication contains frost depth data collected every two weeks in two peatlands instrumented for hydrologic monitoring at the Marcell Experimental Forest (MEF) from 1985–ongoing, only from February until the end of frost during Spring. The variables measured are depth to frost layer, frost thickness, and frost occurrence as percent of area. The three measurements provide information on the depth, duration, and extent of a frost layer. The Marcell Experimental Forest in Itasca County, Minnesota is operated and maintained by the USDA Forest Service, Northern Research Station, and was formally established in 1962 to study the ecology and hydrology of peatlands.The Marcell Experimental Forest was formally established in 1962. The MEF contains six watersheds (and other study sites), each consisting of an upland portion and a peatland that is the source of a stream leaving the watershed. The watersheds and environmental monitoring at the MEF are part of a long-term research program on the hydrology and biogeochemistry of watersheds with uplands and northern peatlands (Kolka et al. 2011).Additional information about the MEF, its instrumentation, and data can be found at https://www.nrs.fs.fed.us/ef/marcell/ and in Sebestyen et al. (2011).
