title: NDVI images derived from the 2006 AISA hyperspectral imagery of the GCE domain for vegetation

description: Airborne Imaging Spectrometer for Applications (AISA) Eagle hyperspectral imagery were acquired on June 20-21, 2006, by the Center for Advanced Land Management Information Technologies (CALMIT). This included ten flight lines flown for the examination of salt marsh and upland vegetation and water for spectral properties at 1 m spatial resolution. For all vegetation images, the Normalized difference vegetation index (NDVI) was calculated. NDVI uses the ratio of reflectance in the red and NIR wavelengths (NDVI = (NIR799 - RED675)/ (NIR799 + RED675)) to derive an index of plant vigor (Rouse et al., 1974). The subscript values are the wavelength band centers used to calculate NDVI. Values indicate the amount of green vegetation present in the pixel—higher NDVI values indicate more green vegetation. Vallid results fall between -1 and +1.

title: Cross-site comparison of historical trends in marsh change at three LTER sites: GCE, VCR, and PIE.

description: The data provided here are shapefiles which were generated from digitizing historical maps and aerial photographs for a cross site comparison of changes in marshes at the Plum Island Ecosystem (PIE), Virginia Coast Reserve (VCR), and Georgia Coastal Ecosystems (GCE) Long Term Ecological Research (LTER) sites. This dataset includes shoreline shapefiles digitized for 3 time intervals at each site: 1930s/40s, 1950s/70s, and 2013 as well as a table of results from the shoreline change analysis. Centerlines for all the channels were generated from the shoreline shapefiles and are attributed with Strahler (1965) channel order and sinuosity. Additionally, this dataset includes shapefiles of important features (channels, upland, ponds, tidal flats) digitized for each of three sites at three time intervals.

title: Radon Surveys in the Duplin River near Sapelo Island, Georgia from July 2016

description: This study measured dissolved radon-222 in transects upstream throughout the Duplin River. Radon serves as a tracer of groundwater discharge into the surface water, so this survey was conducted to assess spatial patterns of groundwater input into the Duplin River. Radon counts were integrated over 10 minute counting cycles, so lateral resolution of the survey is determined by the boat speed. Transects were begun at high tide and at low tide during both spring and neap tide.

title: Continuous groundwater well temperature, salinity and water level measurements at the GCE-LTER Seawater Addition Long-Term Experiment (SALTEx) site from May 2014 to February 2018

description: The Georgia Coastal Ecosystems LTER Seawater Addition Long-Term Experiment (SALTEx) is a large-scale field experiment designed to simulate saltwater intrusion in a tidal freshwater wetland to predict how chronic (Press) and acute (Pulse) salinization will affect this and other tidal freshwater ecosystems. In order to characterize groundwater salinity, temperature, and plot flooding following experimental manipulation, unvented water pressure, temperature and conductivity were continuously measured in a PVC groundwater well installed at the SALTEx site. Measurements were made at the bottom of the well using a submerged Schlumberger CTD-Diver logger every 15 minutes from 30-May-2014 to 14-Feb-2018. In February 2016 a second CTD-Diver was deployed near the top of the well. Data were downloaded from the loggers using Diver Office communication software, then imported into MATLAB for post-processing, quality control and documentation. Raw, unvented pressure readings were corrected for atmospheric pressure and sensor height from the bottom of the well to generate corrected pressure readings, then water level, salinity and density were calculated from the measured variables using UNESCO algorithms. These data were collected as part of the Georgia Coastal Ecosystems LTER SALTEx project (http://gce-lter.marsci.uga.edu/public/app/send_project_eml.asp?id=73), and will be updated annually.

title: The dynamics of marsh-channel slump blocks: an observational study using repeated drone imagery

description: We analyzed the spatial and temporal dynamics of slump blocks within Dean Creek, a creek located on Sapelo Island (GA) and surrounded by salt marsh. To accomplish this, we utilized 11 images of Dean Creek captured between March 2020 and March 2021, which were acquired by using a DJI Matrice 210 UAV. For each image, we manually digitized the perimeters of slump blocks, which have the distance from intact marsh boundary exceeding 0.3 m. These digitized perimeters were subsequently converted into polygons to determine the size, number and cumulative area of slump blocks in each image. Temporal changes to the slump blocks between subsequent images were also analysed. The coordinate system of these polygon data is WGS 1984 UTM Zone 17N.

title: Annual summaries of daily observations from the USGS Streamflow Gauging Station on the Altamaha River near Doctortown, Georgia, for 1932 to 2004

description: Daily averaged river discharge data were obtained from the United States Geological Survey for streamflow gauging station USGS 02226000 on the Altamaha River near Doctortown, Georgia. Processed tabular data were downloaded from the USGS real-time web server (http://waterdata.usgs.gov/nwis/) by the Georgia Coastal Ecosystems LTER project, documented, and standardized to metric units. Missing values of mean discharge were estimated by cubic spline interpolation to fill in data gaps of five or fewer consecutive days. Annual summary statistics were then calculated from daily values aggregated by year.

title: Fall 2017 grasshopper monitoring -- mid-marsh grasshopper abundance and species diversity at eight GCE LTER sampling sites

description: Grasshopper abundance and species diversity were investigated at eight sampling sites within the Georgia Coastal Ecosystems (GCE) LTER study area in July and August 2017. Visual surveys were conducted along 8 2m by 10m transects randomly allocated within the mid-marsh zone at each site. All grasshoppers observed within each transect were counted and identified to species, if possible. This survey was conducted as part of the GCE invertebrate monitoring program, and will be performed annually to assess long-term changes in relative species abundances across the GCE study area.

title: Mollusc population abundance monitoring: Fall 2001 mid-marsh and creekbank infaunal and epifaunal mollusc abundance based on collections from GCE marsh, monitoring sites 1-10

description: This data set is the Fall 2001 estimate of infaunal and epifaunal mollusc abundance at the GCE-LTER marsh sites used for population monitoring. Species abundance was determined by hand-collecting all the infaunal and epifaunal molluscs from within quadrats of known area in mid-marsh and creekbank zones (n = 4 quadrats per zone) at all sites. The molluscs were returned to the lab, fixed in fomalin, transferred to and preserved in ethanol, counted and measured (size data is reported separately). The counts were converted to number per square meter. Gastropod species are listed first, followed by bivalve species. Size distribution data for these collections may be found in the GCE-LTER data set INV-GCEM-0310b.
