Alkalinity, organic carbon, nitrogen, and major anions for Dead Run, Baltimore County, MD USA

This resource includes stream chemistry for Dead Run, Baltimore County, Maryland. This data set is part of the Urban Critical Zone Cluster in the NSF Critical Zone Collaborative Network. Stream grab samples are collected biweekly and analyzed for alkalinity, total organic carbon, dissolved organic carbon, total nitrogen, total dissolved nitrogen, bromide, chloride, fluoride, nitrate-nitrogen, nitrite-nitrogen, orthophosphate phosphorous, and sulfate. Stream sampling sites are co-located with USGS stream gaging stations 01589315 (DR4), 01589312 (DR5), and 01589330 (DRKR). Data are collected for the purpose of (1) trend analysis as a function of space and time; (2) evaluation of the effects of regional geology, anthropogenic perturbations, and weathering processes on stream chemistry; and (3) comparison with stream chemistry from other sites in the Urban CZ cluster.

本资源包含了马里兰州巴尔的摩县Dead Run的河流化学数据。该数据集隶属于美国国家科学基金会（NSF）临界带协作网络中的城市临界带集群。河流采样样本每周收集两次，并对其碱度、总有机碳、溶解有机碳、总氮、溶解总氮、溴、氯、氟、硝酸盐氮、亚硝酸盐氮、正磷酸磷和硫酸盐进行化学分析。河流采样点与USGS河流流量监测站01589315（DR4）、01589312（DR5）和01589330（DRKR）位置重合。数据收集旨在（1）分析空间和时间趋势；（2）评估区域地质、人为扰动和风化过程对河流化学的影响；（3）与城市临界带集群中其他地点的河流化学进行比较。
