A research opportunity exists for a Senior fellow to explore the national data sets accumulated by the EPA Office of Water, Office of Research and Development and the States on the Nation’s aquatic resources (Coastal Water, Rivers and Streams, Lakes and Reservoirs, and Wetlands) under the National Aquatic Resource Surveys (NARS). For the past 12 years, the EPA and States have sampled a suite of biological, chemical, and physical habitat indicators at 1,000 sites every across the conterminous US annually in order to assess the status and trends in the condition of the Nation’s aquatic resources and the anthropogenic disturbances that alter them.

Three primary areas of research focus are of interest to EPA. The first is evaluation and improvement of the existing indicators used in the EPA assessments and the approaches used to establish the assessment thresholds against which each indicator is evaluated. The second is to improve the level of diagnostic capabilities available from the data to aid in determining linkages between human activities and the biological, chemical and physical habitat conditions found during the annual surveys. The third area is to mine the data for ecological insights that can be gained from synoptic surveys. The NARS data sets are quickly becoming the largest available data sets in terms of number of locations and the comprehensive set of variables on aquatic biology, chemistry and physical habitat structure. The EPA staff focuses on national and regional assessments of these data and yet we believe much more information on ecological characteristics of the Nation’s water resources can be gleaned from the data. The applicant is encouraged to develop novel research questions based on her/his research interests, in collaboration with the Adviser, to produce peer-reviewed publications.

We are a highly-collaborative team of research scientists from EPA and the States in the conterminous United States. We seek a Senior research fellow willing to locate on-site with us to pursue this research opportunity for one year with possible extension to a second year. The successful applicant must demonstrate experience with analyses of national aquatic data sets in at least two of the four aquatic resources (coastal waters, rivers and streams, lakes and reservoirs, and wetlands). Additional information on NARS can be found on the US EPA’s website ( 

The successful Senior Fellow will work with Principal Investigator Dr. Steve Paulsen and his associates in Corvallis and EPA Office of Water. This position requires interaction with EPA and State scientists at various institutions.
