Abstract

This resource includes water isotope data from Difficult Run, Virginia. Stream grab samples were collected as a synoptic spanning one day. Samples were analyzed for d18O and d2H on a Picarro L 2130-i water isotope analyzer at UMBC. Data were collected for the purpose of cross-site comparison with other sites in the Urban CZ cluster. The furthest downstream sampling sites is co-located with USGS stream gaging station 01646000. This data set is part of the Urban Critical Zone Cluster in the NSF Critical Zone Collaborative Network.
