  2. Justification Airborne contaminants Marine contaminants Freshwater contaminants Southeast Alaska Network Inventory and Monitoring Program

  3. Justification ? M. Humling/USFS Southeast Alaska Network Inventory and Monitoring Program

  4. Objectives Initial assessment: baselines, geographic and landscape variability? Create long-term status and trends monitoring program for Hg and POPs P. Kaiser/USFWS NPS Photo Source: Wikipedia.com T. McCabe/USDA NRCS Southeast Alaska Network Inventory and Monitoring Program

  5. Logistics and Budget Todd O’Hara Lab, UAF Lisa Hoferkamp, UAS 2007 initial assessment (Nagorski et al.) = $85K FY12 funding for protocol development (O’Hara et al.) = $55K (incl. initial literature review) Andres Lopez, UAF Grad student (protocol development) Southeast Alaska Network Inventory and Monitoring Program

  6. What we’re learning Generally, the watersheds of SEAN parks are quite clean Mercury and POPs found in all watersheds, but no human or wildlife health exceedances Streamwater and sediments extremely low levels But… Age-1 coho elevated mercury levels (up to 80 ng/g) Southeast Alaska Network Inventory and Monitoring Program

  7. What we’re learning Mayflies Southeast Alaska Network Inventory and Monitoring Program

  8. What we’re learning Age-0 coho salmon watershed age = methylmercury Southeast Alaska Network Inventory and Monitoring Program

  9. What we’re considering Fish tissue Lakebed sediments (from Van Metre and Mahler 2005) (from McIntyre 2004) Southeast Alaska Network Inventory and Monitoring Program

  10. Program Delivery + SEAN staff Southeast Alaska Network Inventory and Monitoring Program
