Survey Data for Loon Occupancy in Freshwater Lakes, National Petroleum Reserve-Alaska, 2011-2014 Survey Data for Loon Occupancy in Freshwater Lakes, National Petroleum Reserve-Alaska, 2011-2014
These data are in one table of territory occupancy data for loons and presence/absence data for fish species based on survey information for Pacific (Gavia pacifica) and Yellow-billed Loon (G. adamsii) and five species of fish (Alaska blackfish, arctic grayling, broad whitefish, least cisco, ninespine stickleback) from freshwater lakes on the Arctic Coastal Plain in northern Alaska, 2011...
Coastal Cliff Top and Toe Delineation Derived from Lidar for Puerto Rico: 2018 Coastal Cliff Top and Toe Delineation Derived from Lidar for Puerto Rico: 2018
The National Assessment of Coastal Change Hazards project aims to understand and forecast coastal landscape change. This dataset delineates coastal cliff features (cliff tops, toes, and 3D elevation transects) to assess the hazard posed by eroding coastal cliffs in Puerto Rico, Culebra, and Vieques. The delineation of cliff tops and toes can be used as an input into cliff hazard metrics...
Seafloor Elevation Change From 2002 to 2016 in the Upper Florida Keys Seafloor Elevation Change From 2002 to 2016 in the Upper Florida Keys
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes in the Upper Florida Keys (UFK) from Triumph Reef to Pickles Reef within a 242.4 square-kilometer area. USGS staff calculated changes in seafloor elevation from 2002 to 2016 using light detection and ranging (lidar)-derived data acquired by the USGS in...
Fire impacts on permafrost in Alaska: Geophysical and other field data collected in 2015 Fire impacts on permafrost in Alaska: Geophysical and other field data collected in 2015
Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability...
Shoreline delineations for 21 Subestuaries in the Chesapeake Bay 2010-2014. Shoreline delineations for 21 Subestuaries in the Chesapeake Bay 2010-2014.
In many coastal regions throughout the world, there is increasing pressure to harden shorelines to protect human infrastructures against sea level rise, storm surge, and erosion. These data reflect the digitization of the shorelines of 21 sub-estuaries throughout the Chesapeake Bay (USA) as observed from 2010 through 2014. Shoreline segments are classified into one of seven shoreline...
Data for Gulf Sturgeon Bayesian Network Model Data for Gulf Sturgeon Bayesian Network Model
This USGS Data Release represents tabular and geospatial data for the Gulf Sturgeon Bayesian Network Model. The Gulf Sturgeon is a federally listed, anadromous species, inhabiting Gulf Coast rivers, estuaries, and coastal waters from Louisiana to Florida. The data release was produced in compliance with the new 'open data' requirements as way to make the scientific products associated...
