Plant richness survey of mainland, barrier island and back-barrier hammock island locations around Sapelo Island and St. Simons Island, Georgia, in June-July 2005
I conducted a plant richness survey of 59 sites around Sapelo Island and St. Simons Island, Georgia, in June-July 2005. Sites were chosen to include a range of mainland, barrier island, and back-barrier hammock island locations. All sites were dominated by salt marsh plant species, primarily Spartina alterniflora. To provide a general indication of the salinity conditions prevailing at each site, I measured salinity of the nearest body of water with a refractometer on the date that the site was sampled. Plant richness was documented along a single 5.0m wide transect at each site. Each transect began at the lower elevational limit of vegetation and continued perpendicular to the water's edge to the shrub community at the upper marsh border. Plant presence was noted in a series of nested subplots within a 1.0m x 5.0m plot at each meter along the transect. The results posted here are sites, position, salinity, and the site pool, or species encountered at the site.
Archaeological shovel test data for Little Sapelo Island, Mary Hammock, Patterson Island, and Pumpkin Hammock; Spring 2007, Summer 2007 and 2008
The purpose of this study was to determine the human occupational history of Little Sapelo Island, Mary Hammock, Patterson Island, and Pumpkin Hammock in McIntosh County, GA. During the Spring of 2007 and Summers of 2007 and 2008, a systematic archaeological shovel test survey was performed at a closely-spaced interval of 20 meters. The shovel test grid was laid out using a Trimble GPS, in accordance with the Universal Trans Mercator coordinate system Zone 17, and the North American Datum of 1927 (with a typical accuracy between 1 and 6 m). Teams of two people would go to these locations, dig holes (typically 50 cm in diameter and 1 m deep), and put the soil through wire hardware cloth with a mesh size of 0.6 cm (i.e., 0.25 inch). All cultural material (except shell) were collected and put in labeled plastic bags. Only some shell samples were kept for future analysis. Ceramics were classified to determine surface treatment/ decoration, temper, and rim form, with the ultimate goal of determining their period of use. All of the data related to these shovel tests were entered into a spreadsheet, and that spreadsheet was turned into an ArcGIS point shapefile for analysis. These data are available for professional archaeologists only. Please contact the investigator by E-mail if you would like a copy of these data.
Survey of grasshopper abundance in GCE LTER hammock sites and five GCE LTER study sites
Grasshopper abundance and family diversity were investigated at fifty-five hammock sampling sites and five Georgia Coastal Ecosystems GCE LTER study sites in June-July 2007. Each hammock site had six permanent study plots which were previously laid out. The investigators started at each of these plots and walked to the closest clump of Spartina alterniflora, measuring his or her paces. Grasshopper abundance was conducted along a 10m by 2m transect and identified to family.
Summer 2007 crab population survey based on crab hole counts in fifty-four GCE LTER Hammock sites and four GCE LTER study sites
Crab abundance was investigated at fifty-four hammock sampling sites and four Georgia Coastal Ecosystems (GCE) LTER study sites in June-July 2007 by counting crab holes as a proxy measurement. Each hammock site had six permanent study plots which were previously laid out. Crab holes were counted within a random location inside those six plots at each hammock. Crab holes were counted within a 625 cm^2 area and species were not differentiated in the count, but noted. This method estimates total crab abundance in each study site.
Summer 2007 mollusc population survey in fifty-five GCE LTER Hammock sites and five GCE marsh monitoring sites
Mollusc species and abundance was determined within fifty-five GCE LTER hammock sites and five GCE LTER study sites in June-July 2007. Species abundance was determined by hand-collecting all molluscs from within quadrats of known area at six plots at each site. Molluscs were brought back to the lab, preserved in ethanol, then counted and measured (size data is reported separately).
GCE-LTER Hammock Well Vegetation and Invertebrate Monitoring - July 2008
In July 2008 the GCE LTER program selected two hammocks for intensive study: HN_i_1 and PC_i_29. HN_i_1 is of Holocene origin and is located adjacent to Blackbeard Island to the north of Sapelo Island, Georgia. PC_i_29 is also of Holocene origin and is located adjacent to the south end of Sapelo Island. These hammocks are of similar size, with similar vegetation zones in the high marsh environment. Groundwater well transects were established that run from the upland, through the marsh, and up and over the upland area of each hammock. Two permanent plots were established at each well in order to characterize the plant and invertebrate diversity and abundance by surveying plots once a year. This data set includes the results of July 2008 monitoring studies.

Summer 2007 survey of plant presence and abundance at fifty-five GCE LTER Hammock sites and five GCE marsh monitoring sites
Presence and abundance of plant species was determined at the six permanent monitoring transects within fifty-six GCE LTER hammock sites and five GCE LTER study sites in June-July 2007. Plant presence was determined by placing a 1 m x 1 m qaudrat at two meters from the upland border of the study site’s permanent monitoring transect and noting all species present. In the center of the quadrat, an additional 0.5 m x 0.5 m qudarat was placed to determine percent cover of each species. Plant height was also measured and recorded that the four corners of the 0.5 m x 0.5 m qudarat.
Groundwater well pressure, temperature, conductance, salinity and oxygen measurements for GCE-LTER study hammock HN_i_1 from 30-Oct-2008 to 03-Dec-2013
Groundwater pressure, temperature and other parameters (e.g. conductance, salinity, oxygen and pH) were measured using various instruments installed in PVC wells at the GCE-LTER HN_i_1 holocene study hammock from 30-Oct-2008 to 03-Dec-2013. Observations were logged continuously at 15 minute intervals, and accumulated data were downloaded from loggers using manufacturer-provided communications software semi-monthly, then imported into MATLAB for post-processing, quality control and documention. Raw, unvented pressure readings were corrected for atmospheric pressure and sensor height from the bottom of the well to generate corrected pressure readings. Separate data tables are provided for each combination of instrument and well due to differences in parameters measured and post-processing steps, but all tables include detailed information on location and well characteristics to support integration and analysis. These data were collected as part of the Georgia Coastal Ecosystems LTER Intensive Hammock Characterization and Hammock Groundwater Modeling projects, and will be used for groundwater modeling studies at two marsh hammocks on Sapelo Island, Georgia.

High frequency sediment surface temperature measurements at GCE-LTER study hammock PC_i_29 from 15-Aug-2008 to 24-Sep-2012
Sediment surface temperature was recorded at 5 minute intervals adjacent to 7 groundwater wells installed at the GCE-LTER study hammock PC_i_29 on Sapelo Island, Georgia, from 15-Aug-2008 to 24-Sep-2012. Temperature was measured using Onset Hobo Tidbit temperature loggers that were placed onto the surface of the sediment in shallow PVC enclosures to protect against solar radiation. Data were downloaded from the logger and processed using the manufacturer's software, then imported into MATLAB for post-processing, quality control and documention. Individual data tables were created for each location to minimize file size for analysis, but complete location and deployment information are included in each table to facilitate integration. These data were collected as part of the Georgia Coastal Ecosystems LTER Intensive Hammock Characterization project to illucidate the timing of marsh inundation, and will be used for groundwater modeling studies at two marsh hammocks on Sapelo Island, Georgia.
Vibracore and Tree Stump Data from the Marsh Near Mary Hammock, McIntosh County, GA
The purpose of this study was to determine the geologic/ sedimentologic history of the marsh near Mary Hammock, a marsh island in McIntosh County, GA. During the Summer of 2009, a vibracore machine was used to extract six sediment cores (MT01 through MT06) from the marsh north of Mary Hammock. In addition, tree stumps buried under the marsh were recorded, and one was extracted and analyzed, to facilitate in understanding the sedimentological history of the marsh. A GPS unit was used to record the precise locations and elevations of the core extraction sites and stumps. The cores were then transported to the Georgia Southern Coastal Research Lab at the Skidaway Institute of Oceanography (SkIO), in Savannah, GA, for analysis. The tree stump was brought back to the University of Georgia for analysis. Although there was a large degree of bioturbation in the marsh near Mary Hammock, sediment core analysis (visual inspection, X-Ray analysis, particle size analysis, and analysis of organic matter content), and stump analysis (species determination and radiocarbon dating), revealed three main facies in the marsh. The topmost layer is recent marsh. The middle layer is a sandy layer, representing the former upland surface prior to sea level rise, inundation, and marsh formation (around 5,000 to 4,000 years ago). The bottom layer is a highly compact greenish-gray clay layer. The conclusion is that the former upland surface, consisting mostly of sandy soils, was inundated due to sea level rise around 4,200 B.P. Marsh sedimentation occurred after this, depositing fine-grained sediments on top of the sandy surface (Turck and Alexander, 2013).
