Baltimore Ecosystem Study LTER site, station USGS Station #01589180, Gwynns Falls at Glyndon, MD, study of sulfate in streamwater in units of milligramsPerLiter on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Baltimore Ecosystem Study LTER (BES) contains sulfate in streamwater measurements in milligramsPerLiter units and were aggregated to a yearly timescale.

Baltimore Ecosystem Study polar organic contaminant integrative sampler data for pharmaceuticals and personal care products in core sites within Gwynns Falls watershed and reference sites.
An ongoing component of the Baltimore urban long-term ecological research (LTER) project (Baltimore Ecosystem Study, BES) is the use of the watershed approach and monitoring of stream water quality to evaluate the impacts of multiple chemical stressors on urban stream ecosystem functioning within Baltimore. The LTER research has focused on the Gwynns Falls watershed, which spans a gradient from highly urban, urban-residential, and suburban zones. In addition, a forested watershed serves as a reference. The long-term sampling network includes four longitudinal sampling sites along the Gwynns Falls mainstem, as well as several small (40-100 ha) watershed within or near the Gwynns Falls, providing data on water quality in different land use zones of the watersheds. Each study site is continuously monitored for discharge and is sampled weekly for water chemistry. Those data are available elsewhere on the BES website. We are interested in studying the presence and concentrations of pharmaceuticals and personal care products (PPCPs) within urban streams, and then linking these PPCPs with various stream ecosystem functions. To quantify the concentrations of PPCPs in streams, we deploy polar organic contaminant integrative samples (POCIS), which integrate all organic contaminants that pass by them in a stream over a set period of deployment. These POCIS allow us to integrate the total amount of PPCPs within a stream over a set period of time, and then to relate these concentrations with other ecosystem processes. We monitored PPCP concentration in four suburban to urban sites within the Gwynns Falls, as well as one exurban and one forested stream monitoring site. Each POCIS was deployed for two weeks at a stream monitoring site in March 2012. After completion of the sampling period, POCIS were removed from the streams and shipped on ice to the University of Nebraska for extraction and quantification of recovered compounds. This dataset includes all compounds extracted and q
