Marcell Experimental Forest monthly aquifer groundwater chemistry at the S2 catchment, 2007 - ongoing

This data set reports groundwater chemistry for an aquifer well in the uplands of the S2 catchment at the Marcell Experimental Forest (MEF) in Itasca County, Minnesota. Aquifer groundwater has been collected monthly. Samples are measured for pH, specific conductivity, anions (chloride, sulfate), cations (calcium, magnesium, potassium, sodium, aluminum, manganese, strontium), silicon, nutrients (ammonium, nitrate, soluble reactive phosphorus, total nitrogen, total phosphorus), and total organic carbon. Occasionally, stable water isotopes have been measured. The MEF is operated and maintained by the USDA Forest Service, Northern Research Station.
