  1. USGS GLRI Programs

  2. National Monitoring Network for Coastal Waters (NMN) Tributary Sites

  3. Water Column • Sample at stream gage location at about half of the NMN sites. • Collect monthly and storm event samples. • Use automated samplers when feasible. • Add multi-sensor probe at most sites. • Physical Parameters, Nutrients, Major Ions, Suspended Sediment, Pharmaceuticals and Personal Care Products

  4. Water Monitoring (continued) • Monitor further up the basin at three of the tributaries. • 2 urban watershed (3 sites), 1 ag watershed (3 sites), • Look for sub-basins without multiple point sources (such as WWTP, CSSO’s, and CAFO’s) to help differentiate between sources of contaminants at the mouths of the rivers.

  5. Sediment Traps • Install horizontal sediment traps at AOC’s to gather baseline data before and after remediation. • Collect suspended sediment samples for ppb organic analysis for PAH’s and Total PCB’s in Bed sediment, Alkylated PAH’s in bed sediment. • Bottom samples for OC’s and PCB’s in bed sediment.

  6. Bedload Sampling

  7. National Monitoring Network for Coastal Waters (NMN) Tributary Sites

  8. Great Lakes scientists are asking ecosystem-level questions, at different spatial scales Rivermouth Coastal wetland Deepwater Great Rivers Beaches Terrestrial

  9. Linking Science Across Habitats • Holistic, systems level approach to ecosystem management • Unify ideas and language among Great Lakes manager and scientists • Tool that assists Great Lakes programs assess the state of the ecosystem, science needs, and management strategies

  10. Proposed Framework • Identify key processes that influence ecosystem health in the Great Lakes • Open-Lake • Coastal/Nearshore • Watershed • Related Processes to specific goals, issues, management concerns, etc. • Example: Lake Michigan LaMP goals, • Determine gaps in monitoring and our understanding of key processes that limit our ability to attain these goals

  11. Biological Processes: nutrient input and cycling Biological Processes: nutrient input and cycling Biological Processes: nutrient input and cycling Biological Pollution: Development cycle of cyanobacteria Biological Pollution: Development cycle of cyanobacteria Biological Pollution: Development cycle of cyanobacteria Long range transport, Lake Mixing/Large scale currents/Seiches Circulation and deposition, Retention time Stream loading and flow, groundwater pathways, Substrate-attachment Watershed substrate, area, and slope; Sediment dynamics Substrate, Retention and dispersion, Coastal energy
