Oxygen and nitrogen stable isotopic composition of dissolved nitrate for Pennypack Creek, Philadelphia, PA, USA

This resource includes nitrate isotope data from Pennypack Creek, Philadelphia, PA. Stream grab samples are collected biweekly and are analyzed for d15N-Nitrate and d18O-Nitrate. Data are collected for the purpose of cross-site comparison with other sites in the Urban CZ cluster. Sampling sites are co-located with USGS stream gaging stations 01467048 (PPRH) and 01467042 (PPPI). This data set is part of the Urban Critical Zone Cluster in the NSF Critical Zone Collaborative Network.本数据集涵盖美国宾夕法尼亚州费城彭尼帕克溪（Pennypack Creek）的硝酸盐同位素实测数据。研究团队每两周采集一次河道瞬时水样，对样品中的δ¹⁵N-硝酸盐（原文记为d15N-Nitrate）与δ¹⁸O-硝酸盐（原文记为d18O-Nitrate）开展实验室分析。本数据集的采集目标为与城市关键带集群（Urban Critical Zone Cluster）内的其他站点开展跨站点对比研究。采样站点与美国地质调查局（USGS）的两处河道测流站——编号01467048（PPRH）及01467042（PPPI）——同址布设。本数据集隶属于美国国家科学基金会（NSF）关键带协同网络下设的城市关键带集群。
