Description: A minimum of four water quality data loggers are continuously deployed at four permanent locations across each reserve to record measurements of conductivity, salinity, temperature, pH, dissolved oxygen, turbidity, and water level at fifteen minute intervals. At these same four water quality sampling stations, each reserve also collects monthly measurements of water column nutrients (e.g., nitrate, nitrite, ammonia, and ortho-phosphate) and chlorophyll-a concentrations, In addition, diel sampling (12 samples per a 25 hour time period) for nutrients and chlorophyll-a occurs at a minimum of one site each month.

Description: Erosion monitoring techniques are applied to six sites across the Reserve to document linear changes in shoreline movement and erosional edge dynamics.

Description: Total of 14 sampling stations spread across the reserve in the five different habitat types. Sampling is based on seasons and occurs one time within the months of each season (4 times per year).

Description: 40 marsh bird sampling stations were randomly located across the Grand Bay NERR. Since the spring/summer of 2005, three replicate surveys have been conducted at each using the standardized National Marsh Bird Monitoring Protocol.

Description: A total of 15 Sets are located along the coastal transition transect at Grand Bay. The SETs are located in groups of three, located in five major vegetation communities along this transect: one group in low marsh (i.e., Spartina alterniflora-dominated marsh), two groups in mid marsh (i.e., Juncus roemerianus-dominated marsh), one group in salt panne habitat, and one group in freshwater marsh (i.e., Cladium sp.-dominated marsh). Placement of the SETs in these vegetation communities will allow provide habitat-specific marsh elevation changes, data which are currently lacking for much of the Gulf coastal transition zones. temporary tide station was installed in the summer of 2010 and will be removed in the late summer, 2011. The SETs have all been installed and initial measurements will be made during the late summer, 2011.

Description: The Grand Bay coastal transition transect extends from marine habitats along the Grand Battures north to mesic longleaf pine flatwoods adjacent to I10 and the Franklin Creek Road. This transect, approximately 12 km in length, intersects or is adjacent to a minimum of 15 different habitats.
