  1. Research and Monitoring Related to Sea Level Rise at the Grand Bay NERR Will Underwood Stewardship Coordinator

  2. Practice and Promote the stewardship of coasts and estuaries through innovative research, education, and training using a placed based system of protected areas. Water Quality Climate Change Habitat Protection

  3. NERRS System Wide Monitoring Program • Graduate Research Fellowship (GRF) Program • Grand Bay NERR site profile (ecological characterization) • Coordinate research with DMR, universities, NOAA, and NERRS • Applied research to local & regional issues

  4. The YSI 6600 EDS Datasonde

  5. MS Phosphates Spill (April 2005) TS Lee (Sep 2011)

  6. Long Term Monitoring • Erosion • Habitat Mapping/Change • SAV • Invasive Species • Marsh Elevations

  7. What is SLAMM? Sea Level Rise Affecting Marshes Model SLAMM simulates the dominant processes involved in wetland conversions and shoreline modifications during long-term sea level rise. A complex decision tree incorporating geometric and qualitative relationships is used to represent transfers among coastal classes.

  8. Irregularly-flooded marsh viability: 2009 to 2025

  9. Irregularly-flooded marsh viability: 2009 to 2050

  10. Irregularly-flooded marsh viability: 2009 to 2075

  11. Irregularly-flooded marsh viability: 2009 to 2100

  12. Effects of fire on water quality, plant production, and accretion in a Juncus roemerianus marsh Primary Research Question: What are the effects of prescribed burning on a salt marsh ecosystem? How does fire affect: • Primary productivity • Accretion processes
