Water isotope data for Pond Branch at Oregon Ridge, Baltimore County, MD, USA

This resource includes water isotope data from Pond Branch at Oregon Ridge, Baltimore County, MD, USA. Stream grab samples are collected weekly to biweekly. Samples are analyzed for d18O and d2H on a Picarro L 2120-i water isotope analyzer at UMBC. Data are collected for the purpose of (1) providing a forested reference site for cross-site comparison with urban sites in the Urban CZ cluster; and (2) calculation of mean watershed transit times by analysis in combination with local precipitation water isotope data. The stream sampling site is co-located with USGS stream gaging station 01583570 This data set is part of the Urban Critical Zone Cluster in the NSF Critical Zone Collaborative Network.

本资源囊括了位于美国马里兰州巴尔的摩县奥勒冈岭Pond Branch的氘氧同位素数据。河流抓取样本每周至每两周采集一次。样品在UMBC的Picarro L 2120-i水同位素分析仪上进行分析，测定其d18O和d2H值。数据收集旨在（1）为森林参照地提供跨站点比较，以与Urban CZ集群中的城市站点进行对比；（2）通过结合当地降水水同位素数据进行分析，计算平均流域传输时间。河流采样点与USGS河流测站01583570共位。该数据集是NSF临界区协作网络中城市临界区集群的一部分。
