Marcell Experimental Forest event based precipitation chemistry, 2008 - ongoing

This data set reports the event-based chemistry of precipitation water that was collected at the Marcell Experimental Forest (MEF) in Itasca County, Minnesota. The data come from sites in two research catchments instrumented for hydrologic monitoring - the meteorological station located in an upland clearing in the S2 research catchment and the S1 bog as part of the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment. Sample collection and analyses started during June of 2008 at the S2 site and is ongoing. Sample collection and analyses started during December of 2013 at the SPRUCE S1 sites and will continue for the duration of the experiment. The MEF is operated and maintained by the USDA Forest Service, Northern Research Station. The SPRUCE experiment is a multi-year cooperative project among scientists of the Oak Ridge National Laboratory operated by UT-Battelle, LLC and the USDA Forest Service, Northern Research Station. The SPRUCE experiment is funded by the US Department of Energy, Biological and Environmental Research Program.

本数据集收录了美国明尼苏达州伊塔斯卡县马塞尔实验林（Marcell Experimental Forest, MEF）采集的降水水样的事件尺度化学特征。数据来源于两个布设了水文监测设备的研究流域监测点位——分别为S2研究流域高地开阔地带的气象站，以及作为“变化环境下云杉与泥炭地响应（Spruce and Peatland Responses Under Changing Environments, SPRUCE）”实验组成部分的S1泥炭沼泽监测点。S2站点的水样采集与分析工作始于2008年6月，目前仍在持续开展。SPRUCE实验S1站点的水样采集与分析工作始于2013年12月，将伴随实验全程持续进行。马塞尔实验林由美国农业部林务局北方研究站（USDA Forest Service, Northern Research Station）负责运营与维护。SPRUCE实验是一项多学科长期合作项目，由UT-Battelle有限责任公司运营的橡树岭国家实验室科研人员与美国农业部林务局北方研究站共同参与实施。SPRUCE实验由美国能源部生物与环境研究项目（US Department of Energy, Biological and Environmental Research Program）资助。
