Tidal marsh biomass field plot and remote sensing datasets for six regions in the conterminous United States Note: This dataset has been revised and superseded by version 2.0, available here: https://doi.org/10.5066/P90PG34S. Remote sensing based maps of tidal marshes, both of their extents and carbon stocks, have the potential to play a key role in conducting greenhouse gas inventories and implementing climate mitigation policies. Our objective was to generate a single remote sensing model of tidal marsh aboveground biomass and carbon that represents nationally diverse tidal marshes within the conterminous United States (CONUS). To meet this objective we developed the first national-scale dataset of aboveground tidal marsh biomass, species composition, and aboveground plant carbon content (%C) from six CONUS regions:...

Agricultural and water-management practices affect the water quality of these canals. Fertilizers added in the EAA flow into the canals and are transported to treatment areas which remove much of the phosphorous in the water, but are not as effective in removing dissolved sulfate. Elevated sulfate concentrations, found downstream in the Water Conservation Areas in the northern Everglades, can stimulate sulfur-reducing bacteria which can also convert inorganic mercury to methyl mercury, a bioaccumulative neurotoxin. Chemistry data at 25 canal sites in southern Florida... Categories: Data; Tags: Broward County, Energy Resources, Geochemistry, Miami-Dade County, Palm Beach County, All tags...

An approach known as decompartmentalization, which involves the removal of levees, canals, and other barriers to flow, has been suggested to aid in the restoration. In the region known as Water Conservation Area 3 (WCA-3), the L-67A and L-67C canals and levees, which bisect WCA-3 into WCA-3A to the north and WCA-3B to the south, are major barriers to natural flow. A test project for the decompartmentalization of WCA-3 has been initiated through the WCA-3 Decompartmentalization and Sheetflow Enhancement Physical Model (DPM). This flow-release test involves reconnecting WCA-3A and WCA-3B through... Categories: Data; Tags: Hydrology, Hydrology, Miami-Dade County, The Everglades, USGS Science Data Catalog (SDC), All tags...

This dataset combines SET-MH data from five different U.S. Geological Survey efforts to monitor surface elevation change in the coastal wetlands of the Greater Everglades region of south Florida. Data from these efforts have been used in the publications by Cahoon and Lynch (1997), Whelan et al. (2005, 2009), Smith et al. (2009), McKee (2011), Breithaupt et al. (2020), Feher et al. (2020), Howard et al. (2020), and Osland et al. (2020). Although some of these data have previously been released...

Water, sediment, and fish samples were collected from Water Conservation Areas 1 (Arthur R. Marshall Loxahatchee National Wildlife Refuge), 2, and 3 and neighboring canals between 2012 and 2019. The sites sampled in Water Conservation Areas 2 and 3 follow hydrologic flow paths. Field measurements reported for surface and pore waters include specific conductance, pH, dissolved oxygen (DO) concentration, and oxidation-reduction potential (ORP). Pore waters were filtered (quartz fiber filter) and measured for major cations, inorganic...
