Abstract: The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2002 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002. Biomass was only calculated for dominant species, including Spartina alterniflora, S. cynosuroides, Juncus roemerianus, and Zizaniopsis miliacea. This data set is based on GCE plant monitoring survey data set PLT-GCEM-0211, and allometric relationships were based on GCE data set PLT-GCEM-0211b. 3. Study Type: Monitoring 4.

Objectives: To investigate the linkages between coastal and distant upland areas in central Georgia mediated by surface and ground water delivery to the coastal zone. This will be addressed by examining the relationship between variability in environmental factors driven by river flow, primarily salinity, and ecosystem processes and structure. 5. Abstract: We propose to establish a Long Term Ecological Research site on the central Georgia coast in the vicinity of Sapelo Island. This is a barrier island and marsh complex with the Altamaha River, one of the largest and least developed rivers on the east coast of the US, as the primary source of fresh water. The proposed study would investigate the linkages between local and distant upland areas mediated by water - surface water and ground water - delivery to the coastal zone. We would explicitly examine the relationship between variability in environmental factors driven by river flow, primarily salinity because we can measure it at high frequency, and ecosystem processes and structure. We will accomplish this by comparing estuary/marsh complexes separated from the Altamaha River by one or two lagoonal estuary/marsh complexes that damp and attenuate the river signal. This spatial gradient is analogous to the temporal trend in riverine influence expected as a result of development in the watershed. We will implement a monitoring system that documents physical and biological variables and use the time trends and spatial distributions of these variables and of their variance structure to address questions about the factors controlling distributions, trophic structure, diversity, and biogeochemistry. An existing GIS-based hydrologic model will be modified to incorporate changes in river water resulting from changes in land use patterns that can be expected as the watershed develops. This model will be linked to ecosystem models and will serve as an heuristic and management tool. Another consequence of coastal development is that as river flow decreases, groundwater flow increases and becomes nutrified. We will compare the effects of ground water discharge from the surficial aquifer in relatively pristine (Sapelo Island) versus more urbanized (mainland) sites to assess the relative importance of fresh water versus nutrients to productivity, structure and biomass turnover rate in marshes influenced by groundwater. We will also investigate the effect of marine processes (tides, storm surge) on mixing across the fresh/salt interface in the surficial aquifer. Additional physical studies will relate the morphology of salt marsh - tidal creek channel complexes to tidal current distributions and exchange. These findings will be incorporated into a physical model that will be coupled to an existing ecosystem model. The land/ocean margin ecosystem lies at the interface between two ecosystems in which distinctly different groups of decomposers control organic matter degradation. The terrestrial ecosystem is largely dominated by fungal decomposers, while bacterial decomposers dominate the marine ecosystem. Both groups are important in salt marsh-dominated ecosystems. Specific studies will examine, at the level of individual cells and hyphae, the relationship bacteria and fungi in the consortia that decompose standing dead Spartina and other marsh plants and examine how, or if, this changes along the salinity gradient. 6.

History of Land Use and Disturbance: GCE1 -- Oct 01, 2000: Permanent plots were established in two nominal marsh zones based on marsh structure -- creek zone and high marsh -- and eight plots were randomly located in each zone and marked with stakes. Oct 01, 2001: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. No significant disturbance was observed, and no plots were replaced. Oct 16, 2002: Plots were examined for signs of disturbance by wrack inundation, animal activity, and creek bank erosion. The following plots were disturbed by wrack (some have no shoots): C4, C5, C6, C7, C8. The following creekbank plots are on creekbank areas that are collapsing: C5, C6, C8. No disturbance by animal activity was observed and no plots were replaced.

Climate: Climate summary for Sapelo Island, Georgia, based on NWS data from 1980-2010: Daily-aggregated Values: Mean (sample standard deviation) mean air temperature: 20.09°C (7.28°C) minimum air temperature: 15.02°C (7.96°C) maximum air temperature: 24.82°C (6.98°C) total precipitation: 3.26mm (10.3mm) Yearly-aggregated Daily Values: Mean (sample standard deviation) total precipitation (1980-2010): 1124mm (266mm) 2. Experimental or Sampling Design a. Design Characteristics: A quadrat survey was conducted in October 2002 to measure the species and size distribution of plants in the permanent plots at 10 GCE LTER sampling sites. b. Permanent Plots: Permanent plots were established in the marsh areas at each GCE sampling site in October, 2000. Each site was divided into two nominal zones based on marsh structure -- creek zone and high marsh -- and eight plots were randomly located in each zone and marked with stakes. Plots are visually inspected prior to each annual survey for signs of disturbance by wrack inundation, wildlife activity, and creekbank erosion. Plots lost due to catastrophic disturbance are replaced with new plots in different locations within the same marsh zone, which are assigned distinct plot numbers. (See history of plot disturbance in the site description section for details). c. Data Collection Duration and Frequency: A stratified random quadrat sampling design was used to determine the species and size distribution of plants in two nominal marsh zones (creek and high marsh) at each GCE LTER sampling site. Beginning of Observations: Oct 14, 2002 End of Observations: Oct 20, 2002 3. Research Methods a. Field and Laboratory Methods: Method 1: Quadrat sampling -- Quadrats were randomly placed within two nominal marsh zones at each site (eight plots per zone) to create permanent plots in October 2000. These plots were used for this study, in addition to five new plots added in October 2001 and two new plots added in October 2002 to replace original plots lost due to catastrophic disturbance. The quadrats were marked using PVC or wooden stakes and varied in size, measuring 0.5m by 0.5m, 1m by 0.5m, or 0.25m by 0.25m, as indicated in the 'Quadrat_Area' data column. Method 2: Plant measurement -- The taxon, shoot height, and flowering status was recorded for each shoot > 10cm in height present in each quadrat. Method 3: Biomass Calculation -- Plant biomass was calculated for predominant flowering plants based on the allometric relationships between plant height, flowering status and biomass calculated by site, zone and species using the formula: ln(Biomass) = constant + htslope*ln(Plant_Height) + flslope*ln(Flowering_Status) Method 4: RTK-GPS Survey of Permanent Plot Locations -- A survey was performed in April 2010 to measure the precise geographic locations and elevations of long-term plant plots at GCE-LTER marsh study sites 1-10. The survey was performed using a Trimble R6 real-time kinematic GPS sytem with Global Navigation Satellite System (GLONASS) support. The base receiver was placed on a permanent cement base installed near each field site, connected to GLONASS satellite services via mobile 3G Internet connection, and allowed to establish a stable benchmark positional fix prior to the survey. A portable wireless rover unit was then used to collect and log horizontal position and vertical elevation data on the ground at the center of each plot. Data were then corrected and analyzed using Trimble Geomatics Office software to determine latitude, longitude and elevation, and plant plot locations were then registered in the GCE-LTER geographic database. Location, Longitude and Latitude columns were then added to the data table based on matching site, marsh zone and plot number of each record to the corresponding plot identifier in the geographic database. For plots that were lost due to catastrophic disturbance prior to 2010 and replaced, the measured location of the the replacement plots were used to provide estimated positional information for the legacy plots, and the estimated values were flagged and the level of uncertainty was described based on the number of times the plot was replaced prior to RTK-GPS survey. b.
