Marsh vegetation and soil survey at Marsh Landing, Sapelo Island GA from July 1999.
To document edaphic and vegetation patterns in a Georgia marsh, I sampled seven vegetation "zones" at Marsh Landing on Sapelo Island in July, 1999. Vegetation zones were delineated based on vegetation composition. I located 8 transects running from the Juncus zone in the high marsh down into the short S. alterniflora zone. The tall Spartina zone was not sampled. I sampled a single quadrat (0.25 m x 0.25 m) in each vegetation zone along each transect, for a total of 56 plots. I measured canopy height with a meter stick. I harvested aboveground biomass within each quadrat, sorted it to species, dried and weighed it. I measured soil water content gravimetrically by drying surface (4 cm deep) soil cores and expressing results as (water mass)/(mass of wet core). I determined porewater salinity by rehydrating dried soil cores with a known volume of deionized water, measuring the salinity of the supernatant after 48 h, and back-calculating to the volume of water originally present. I measured soil organic content as loss on ignition of dried soil cores at 450oC for 12 h. I measured relative elevation of each vegetation zone with a theodolite, with the elevation of the lowest zone arbitrarily set to zero. The resulting dataset describes how plant species composition, richness, height and biomass varies as a function of abiotic conditions in the upper part of a Georgia marsh.

Air temperature, relative humidity, barometric pressure, precipitation, photosynthetically-available and total solar radiation, and wind speed and direction were measured using an automated Campbell Scientific Instruments climate station installed at Marsh Landing on Sapelo Island, Georgia. Observations were logged at 15 minute intervals throughout the study period. The sensors were mounted on a 10m aluminum tower, with wind sensors mounted at the top, light sensors at approximately 5m, and other sensors at 2-3m to minimize interference from the surrounding landscape. This climate station was jointly operated by the Sapelo Island National Estuarine Research Reserve, the Georgia Coastal Ecosystems LTER Project, and University of Georgia Marine Institute.

Variation in Landsat 8-estimated land surface temperature with elevation from Spartina alterniflora marsh cross sections in the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) site and Virginia Coast Reserve (VCR) LTER sites for winter and summer observations spanning 2013-2018
We estimated land surface temperature from top of atmosphere brightness temperature provided by Landsat 8's band 10 (a thermal band). We collected these measurements first for Spartina alterniflora dominated marsh near the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) eddy covariance flux tower. Measurements were collected from pixels along three east-west cross sections that spanned a marsh edge to interior gradient. We extracted Landsat 8 data for all available cloud-free low tide dates during August, September, January and February during the years 2013 to 2018 and associated these with marsh elevation information from a 1 m^2 Digital Elevation Model (DEM), created by Haldik et al 2013, also available from the GCE data catalog (http://dx.doi.org/10.6073/pasta/4c5187ef603f70cd0a77ece24ef0fed9). We rescaled the DEM to the coarser spatial resolution of Landsat 8 (30 x 30 m) where the rescaled elevation was the mean of the constituent DEM values. Ultimately, we used generalized additive models to relate land surface temperature to elevation, while accounting for variation from spatial proximity, transect and sample date. These models revealed that land surface temperature was negatively related to marsh elevation on the marsh platform. We then confirmed the generality of this pattern by rederiving these same relationships for three cross sections of Spartina alterniflora marsh at Virginia Coast Reserve (VCR) LTER for winter sampling dates only (data also included here). DEM data for VCR LTER are available at https://www.vcrlter.virginia.edu/gisdata/LIDAR/USGS2015/. We used custom R functions that can convert Landsat 8 top of atmosphere brightness temperature or top of atmosphere radiance from band 10 data to land surface temperature, which are available at https://github.com/jloconnell/convert_top_of_atmosphere_thermal_to_land_surface_temperature. Currently, a provisional land surface temperature product is available on earthexplorer.usgs.gov, w

Marsh migration land use inferred from historical T-Sheets of the Chesapeake Bay
Detailed methods are listed in the associated publication (Schieder et al., 2018 https://doi.org/10.1007/s12237-017-0336-9). Briefly, we compared the spatial distribution of marshes in nineteenth-century maps to modern aerial photographs for the areas included in 40 NOS topographic sheets ("T-sheets") that included information on simple land types (e.g., marsh, farmland, forests) from the tidal portions of the Chesapeake Bay. Tidal marsh extent was digitized by hand by tracing the boundary between marsh and open water and the boundary between marsh and upland. The marsh-forest boundary was identified as the line between the dense tree canopy and marsh, the marsh-agriculture boundary was identified as the line between agriculture and marsh, and the marsh-water boundary was identified as the line between open water and adjacent land excluding beaches. The areas of agricultural land converted to marsh, forestland converted to marsh, and total upland conversion to marsh were summarized for each T-Sheet.
This Land is Your Land, This Could Be Marsh Land: Property Parcel Characteristics of Marsh Migration Corridors in Rhode Island, USA
<p>These data on Rhode Island property parcels and salt marsh migration projections support a project analyzing their overlap. Salt marshes, critical habitats offering many ecosystem services, are threatened by development, sea level rise (SLR) and other anthropogenic stressors that are projected to worsen. As seas rise, some salt marshes can migrate inland if there is adjacent, permeable, undeveloped land available. Facilitating marsh migration is necessary for coastal resilience efforts, but extensive coastal development can make finding suitable migration corridors challenging. This work seeks to characterize the changes in land use, ownership, and economic value at the property parcel level within projected 2050 marsh extent for the state of Rhode Island, USA. We find that most parcels currently containing salt marsh are publicly owned, whereas most adjacent parcels projected to contain new salt marsh in 2050 are privately owned. Additionally, parcels containing new marsh in 2050 have 47% higher per-hectare assessed values than parcels containing current marsh. We describe the locations and characteristics of parcels within migration corridors with the lowest per-hectare values that may be the most cost-effective for marsh conservation practitioners to protect. This study highlights the expanding land use types and landowner sets that will be involved in marsh conservation decisions, and the economic value of potential migration corridors where costly tradeoffs may be necessary to promote coastal resilience.</p>
