Coastal wetland area change in the Gulf of Mexico, 1985-2020 Coastal wetland area change in the Gulf of Mexico, 1985-2020
These data were used to quantify land area change in a wetlands possible zone of coastal wetlands during a 1985-2020 observation period. The datasets presented in this data release represent annual median estimates of the fractional amount of land, floating aquatic vegetation, submerged aquatic vegetation, and water per Landsat pixel. These data are intended for coarse-scale analysis of...
Environmental DNA and electrofishing data for American eel in the Mohawk and Hudson River Watersheds (ver. 2.0, January 2023) Environmental DNA and electrofishing data for American eel in the Mohawk and Hudson River Watersheds (ver. 2.0, January 2023)
The dataset is composed of five tables containing environmental DNA (eDNA) and electrofishing data from American eel (Anguilla rostrata) surveys conducted on parts of the Mohawk River watershed and tributaries to the Hudson River in New York. The dataset includes (a) eDNA data from 36 sites in the Mohawk River watershed and adjacent areas including parts of the Eastern Erie Canal, Mohawk...
Geodetic Data for USGS Glaciers: Orthophotos, Digital Elevation Models, Glacier Boundaries and Surveyed Positions Geodetic Data for USGS Glaciers: Orthophotos, Digital Elevation Models, Glacier Boundaries and Surveyed Positions
This data release provides geodetic measurements collected since the mid-1940s to characterize the surface elevation, area, and motion of glaciers studied by the U.S, Geological Survey. The primary glaciers of focus are the Benchmark Glaciers of North America which include Gulkana, Wolverine, and Lemon Creek Glaciers in Alaska, Sperry Glacier in Montana, and South Cascade Glacier in...
Pine species distribution maps of the Madrean Sky Islands, United States and Mexico Pine species distribution maps of the Madrean Sky Islands, United States and Mexico
This dataset includes raster species distribution models of five pine species in the Madrean sky islands of Mexico and the United States. Models were trained using a large bi-national field dataset (n = 1,416) of pine species observations. Species distribution models were created for the following pine species: P. arizonica (syn. P. ponderosa var. arizonica); P. discolor (syn. P...
Ecological modeling output for the Everglades Agricultural Area Reservoir 2020 Ecological modeling output for the Everglades Agricultural Area Reservoir 2020
Ecological models facilitate evaluation and assessment of alternative approaches to restore the Greater Everglades ecosystem. The models of particular interest to the South Florida Water Management District for planning for the Everglades Agricultural Area (EAA) Reservoir were: (1) Cape Sable Seaside Sparrow Marl Prairie Indicator, (2) Florida apple snail (native) population model...
Lake Hermitage Marsh Creation? NRDA Early Restoration Project: 2018 and 2020 land-water classifications Lake Hermitage Marsh Creation? NRDA Early Restoration Project: 2018 and 2020 land-water classifications
The Louisiana Coastal Protection and Restoration Authority and the Natural Resource Damage Assessment (NRDA) develop restoration plans in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions...
