Dataset title: Survey of biological, geomorphic, and hydrologic properties across ecosystem states in a non-tidal, salinizing peat marsh in Everglades National Park, Florida, USA: 2019-2020 Dataset ID: doi:10.6073/pasta/dc93e8b2dd8c96b79baa0795ae4882ac Dataset Creator Name: Mr. Lukas Lamb Position: Graduate Student Organization: Florida International University Address: 11200 SW 8th St Miami, FL 33199 Email: llamb009@fiu.edu Name: Dr. Tiffany Troxler Position: Associate Professor Organization: Florida International University Email: troxlert@fiu.edu Dataset Abstract Geographic Coverage Bounding Coordinates Geographic description: The dataset is from a 9 ha coastal, non-tidal peat marsh in the coastal Everglades (25°13’13.17” N, 80°50’36.96” W). This marsh is dominated by sawgrass (Cladium jamaicense), interspersed by the submerged aquatic macrophyte, muskgrass (Chara spp.), unvegetated open water, and to a lesser extent, buttonwood (Conocarpus erectus) and red mangrove (Rhizophora mangle scrub; tree heights < 1.5 m). Soils are histosols (peat) with > 85% organic matter ranging 1.0 - 2.0 m in depth. West bounding coordinate: -80.84725 East bounding coordinate: -80.84336 North bounding coordinate: 25.222762 South bounding coordinate: 25.2216 Temporal Coverage Start Date: 2019-11-01 End Date: 2020-01-16 Data Table Entity Name: FCE1250_Lamb_AltStableState_HydroGeo Entity Description: This data table contains single point measurements of hydrologic and geomorphic variables that were taken from November 2019 to January 2020 in a non-tidal, salinizing peat marsh in the coastal Everglades. Measurements were taken across the 3 ecosystem states found within the peat marsh: emergent marsh (sawgrass dominated), submerged marsh (submerged aquatic vegetation), and unvegetated open water. Hydrologic measurements include surface water depth and porewater salinity (soil depth = 15 cm), while geomorphic measurements include soil surface elevation (rel. North American Vertical Datum of 1988), and soil depth to bedrock. Elevation was measured using real-time kinematic surveys with a Trimble R8.

Biologic measurements include total number of sawgrass per plot, average individual sawgrass aboveground biomass, and total aboveground sawgrass biomass. Methods for biomass estimates are described in Childers et al. (2006). Hydrologic measurements include water depth and porewater salinity (soil depth = 15 cm), while geomorphic measurements include soil surface elevation (rel. North American Vertical Datum of 1988), and soil depth to bedrock. For each hydrologic and geomorphic measurement, three measurements were taken across each plot, then averaged. Standard deviation for all measurements are included in a separate column.
