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

2

3 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 Habitat Protection Climate Change

4

5 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

6 The YSI 6600 EDS Datasonde

7 MS Phosphates Spill (April 2005) TS Lee (Sep 2011)

8 Long Term Monitoring Erosion Habitat Mapping/Change SAV Invasive Species Marsh Elevations

9 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.

10 Irregularly-flooded marsh viability: 2009 to 2025

11 Irregularly-flooded marsh viability: 2009 to 2050

12 Irregularly-flooded marsh viability: 2009 to 2075

13 Irregularly-flooded marsh viability: 2009 to 2100

14 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
