Mollusc population abundance monitoring: Spring 2004 mid-marsh and creekbank infaunal and epifaunal mollusc abundance based on collections from GCE marsh, monitoring sites 1-10
This data set is the Spring 2004 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-0704b2.
Mollusc population size distribution monitoring: Spring 2004 mid-marsh and creekbank infaunal and epifaunal mollusc size distributions based on collections from GCE marsh, monitoring sites 1-10
This data set is the Spring 2004 report of infaunal and epifaunal mollusc species' size distributions at the GCE-LTER marsh sites used for population monitoring. Infaunal and epifaunal molluscs were hand-collected from within quadrats of known area from 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, measured and counted (count data is reported separately). Length of each measurable individual was determined using calipers or small etched rulers under a stereomicroscope. Species abundance and density data for these collections may be found in the GCE-LTER data set INV-GCEM-0704b1. Numbers of individuals of each species in the abundance data file may not correspond exactly to the numbers of individuals in the size data file because some individuals may not have been measureable.

Fall 2006 crab population monitoring: mid-marsh and creek bank abundance based on crab hole counts at GCE marsh, monitoring sites 1-10
This data set is the Fall 2006 estimate of crab densities at the GCE-LTER marsh sites used for population monitoring. Crab abundance was determined by counting the number of crab holes within a 625 cm^2 quadrat and converting the counts to number per square meter. Counts were made in the mid-marsh and creek bank zones (n = 4 per zone) at GCE sites 1 through 10. This method does not differentiate which species made a particular hole and therefore only estimates total crab abundance. Plugged holes were excluded from the counts. Mean density across all sites and zones was 342 m^-2 (+/- 355 s.d.).

Fall 2000 soil organic content survey -- ash-free dry weight analysis for soil samples from 10 GCE LTER sampling sites
Soil core samples were collected from the permanent plots at 10 GCE LTER sampling sites in October, 2000, to survey the fractional organic content in marsh sediments. Surveys will be conducted annually to assess changes in soil organic content in response to environmental factors documented by other GCE monitoring efforts.

Plant community surveys along transects at multiple sites on Sapelo Island and St. Simons Island in Georgia during June and July 2005
I sampled 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 composition of the plant community in 0.5 x 0.5 m quadrats located at 1 m intervals along the transect. This data set is a companion to PLT-GCET-0608, which provides pooled data for sites in Georgia.
