North Carolina Water Science Center Seminars
The North Carolina Water Science Center conducts monthly in-office seminars about various environmental topics. The public is invited to attend. The seminars are usually during lunchtime, so feel free to bring your lunch. If you would like to be notified of upcoming seminars via email, then just send us your name and email address. The list also will be used to notify its members of seminar cancellations or other schedule changes.

Using a Multi-Isotope Approach to Understanding Nutrient Sources and Cycling in Surface- and Groundwater (PDF)
Date: October 5, 2010
Speaker: Megan Young, USGS Branch of Regional Research, Menlo Park, California
Understanding nutrient and organic matter sources, sinks, and biogeochemical cycling is a critical component in environmental studies for both pristine and human-impacted systems. The scale and complexity of large hydrologic systems present logistical, financial, and interpretive challenges due to the difficulty of constraining both sources and biogeochemical dynamics. The use of a multi-isotope (H-C-N-O-S) approach in monitoring studies can provide critical insights into nutrient behavior over large spatial and temporal scales, highlighting both well-established and relatively new stable isotope methods. Studies in the San Joaquin River, Sacramento River, and San Francisco Bay demonstrate how the measurement of stable isotopes in water, nitrate, ammonium, phosphate, and particulate and dissolved organic matter can be used to constrain potential sources and sinks of nutrients, and identify biogeochemical processes that may not be evident through concentration analysis alone.
2010 Water Resources Research Institute Annual Conference: State of Water Resources in North Carolina
Date: March 30-31, 2010
The USGS was an active participant in the March 2010 WRRI converence, "State of Water Resources in North Carolina." The annual WRRI conferences allow participants to explore key issues, opportunities, and questions about North Carolina’s water resources.
Emerging Contaminants: A Water-Quality Odyssey
Date: February 4, 2008
The U.S. Geological Survey has investigated emerging contaminants across the nation, including several rivers and reservoirs in central North Carolina. Mary Giorgino discussed current emerging-contaminants research and presented results of recent investigations in North Carolina.
