Abstract

This resource includes water quality sensor data measured at three stations along the main stem of the Gwynns Falls watershed, spanning an urban to rural gradient of development from Baltimore City to Baltimore County, MD, USA. In addition, two forested reference sites, Baisman Run and Pond Branch at Oregon Ridge, and one urban site, Dead Run (tributary to Gwynns Falls), are instrumented in Baltimore County, MD, USA. Sensor data are collected at a 5-minute frequency by YSI EXO2 sondes that include temperature, specific conductance, turbidity, dissolved oxygen, and pH. In addition, s::can spectrolyser v3 sondes are planned for deployment to measure nitrate-nitrogen and dissolved organic carbon at a 15-minute frequency at 5 of the sites. A Seabird SUNA is currently measuring nitrate-nitrogen at Dead Run at a 30-minute frequency. All Dead Run data are provided in a separate linked resource. High frequency data are collected for the purpose of evaluating event-based water quality /discharge behavior, as a complement to weekly grab-sample stream chemistry data that have been collected by the Baltimore Ecosystem Study since 1998. The six sites are co-located with USGS stream gages. Data are telemetered to UMBC. This data set is part of the Baltimore Social-Environmental Collaborative Urban Integrated Field Laboratory supported by Department of Energy as well as the Critical Zone Collaborative Network supported by NSF.
