Assessing the ecological risk of heavy metal sediment contamination from Port Everglades Florida USA
Port sediments are often contaminated with metals and organic compounds from anthropogenic sources. Remobilization of sediment during a planned expansion of Port Everglades near Fort Lauderdale, Florida (USA) has the potential to harm adjacent benthic communities, including coral reefs. Twelve sediment cores were collected from four Port Everglades sites and a control site; surface...

Using mollusks as indicators of restoration in nearshore zones of south Florida's estuaries
Current south Florida ecosystem restoration efforts are focused on restoring more natural freshwater flow through the wetlands and into the estuaries to reestablish natural salinity gradients, particularly in the nearshore zones. Indicator taxa are used to monitor and assess restoration progress and the current suite of biota used for the estuaries in south Florida (Biscayne Bay, Florida...

Estimating and applying fish and invertebrate density and production enhancement from seagrass, salt marsh edge, and oyster reef nursery habitats in the Gulf of Mexico
Seagrasses, oyster reefs, and salt marshes are critical coastal habitats that support high densities of juvenile fish and invertebrates. Yet which species are enhanced through these nursery habitats, and to what degree, remains largely unquantified. Densities of young-of-year fish and invertebrates in seagrasses, oyster reefs, and salt marsh edges as well as in paired adjacent...

Impacts of Hurricane Irma on Florida Bay Islands, Everglades National Park, U.S.A.
Hurricane Irma made landfall in south Florida, USA, on September 10, 2017 as a category 4 storm. In January 2018, fieldwork was conducted on four previously (2014) sampled islands in Florida Bay, Everglades National Park to examine changes between 2014 and 2018. The objectives were to determine if the net impact of the storm was gain or loss of island landmass and/or elevation; observe...

Faunal and vegetation monitoring in response to harbor dredging in the Port of Miami
Seagrasses are highly productive ecosystems. A before-after-control-impact (BACI) design was used to examine effects of dredging on seagrasses and the animals that inhabit them. The control site North Biscayne Bay and the affected site Port of Miami had seagrass densities decrease during both the before, Fish and Invertebrate Assessment Network 2006-2011, and after, Faunal Monitoring in...

Mangrove Forest Responses to Sea-Level Rise in the Greater Everglades
USGS researchers will utilize long-term soil elevation change data to help advance understanding of soil elevation dynamics and ecological transformations within coastal wetlands of the Greater Everglades.
Salinity and Temperature Data for South Florida Estuarine Mollusks (1994-present)
The Salinity and Temperature Data for South Florida Estuarine Mollusks (1994-present) database contains salinity and temperature readings from modern monitoring sites where live mollusks were observed during fieldwork performed from 1994 to present, salinity and temperature summary statistical data for each species, and location information about the sites where the monitoring data were...
Digital & NDVI Image Capturing Temporal Changes in Vegetation within Wetlands in South Florida
This data set includes images from Dwarf Cypress located within Big Cypress National Preserve. Images were taken multiple times daily from February 2021 to June 2024 using a five-band multispectral camera equipped for normalized difference vegetation index (NDVI) sensing and standard high-quality photographs.
Particle size distribution data from Florida Bay, Everglades National Park, Florida - 2024 analyses of samples collected following Hurricane Irma (2017) (ver. 1.1, May 2025)
In January 2018, a U.S. Geological Survey (USGS) team collected short cores and surface samples from four islands in Florida Bay, Everglades National Park, south Florida (Wingard et al. 2019). The 2018 samples were collected approximately five months after the passage of Hurricane Irma on September 10, 2017, as a category 4 storm. The four islands had also been cored in 2014. The goal of...
Daily evaporation rates computed using five methods at the LZ40 platform in Lake Okeechobee, Florida, December 2012 to December 2016
Daily evaporation rates were calculated at the open-water LZ40-platform in the interior of Lake Okeechobee, Florida, from December 1, 2012 through December 31, 2016 using five methods (Shoemaker et al., 2024); specifically, the Penman, Priestly-Taylor, Mass-Transfer, Simple, and Turc equations. Bowen-ratio energy-budget derived daily evaporation rates calculated from micro-meteorological...
Everglades mangrove vegetation data from 23 long-term plots (1992-2011)
Twenty-three long-term mangrove vegetation plots were established between 1992-1997 within the southwest coastal region of Everglades National Park (Florida, USA) to quantify tree damage and recovery following hurricanes and to understand the effects of global climate change. Many of the mangrove vegetation plots were associated with hydrology, soil porewater, and soil surface elevation...
Potential Accumulation of Soil Organic Matter from Carbon Cycling within Greater Everglades Cypress and Pine Forested Wetlands data
These data quantify components of the carbon cycle within Big Cypress National Preserve in Florida. Continuous data time-series include net ecosystem exchange of carbon dioxide, methanogenesis, and soil bulk density.
