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

Alternate stable states have been shown to occur across disparate ecosystems. In tidal marshes, emergent, vegetated marsh and open water have been identified as alternate stable states. In non-tidal, subtropical coastal marsh systems, eco-hydrogeomorphic feedback loops differ from tidal marshes, yet open water states persist. This dataset originates from a field survey of biological, geomorphic, and hydrologic properties across ecosystem states that occur within a salinizing, non-tidal peat marsh in the coastal Everglades. Ecosystem states surveyed include emergent marsh (sawgrass dominated), submerged marsh (submerged aquatic vegetation), and unvegetated open water. The survey was conducted between November 2019 to January 2020. There are two datasets included: FCE1250_Lamb_AltStableState_HydroGeo includes point measurements of soil surface elevation, bedrock elevation, soil depth, water depth, and porewater salinity across all ecosystem states. FCE1250_Lamb_AltStableState_Bio contains plot-scale (1 m^2) biological measurements from emergent marsh (sawgrass). Biological measurements (total sawgrass, average individual sawgrass biomass, and total sawgrass aboveground biomass), are inherently plot-level but geomorphic and hydrologic measurements were averaged (n = 3) for each plot. Standard deviations are provided.
