U.S. Geological Survey - Gap Analysis Project Species Habitat Richness
The Species Richness Maps included here are based on the Gap Analysis Project (GAP) habitat maps, which are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Individual species habitat distribution models were summed to create the total richness for each vertebrate taxa. The summing process was coded in Pyth
UMRS Floodplain Inundation Attributes
Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS). Here, we present the results of a geospatial surface-water connectivity model in support of ecological investigations fully described in the USGS Open File Report entitled Indicators of Ecosystem Structure and Function for the Upper Miss
Percent of Agriculture Land Subject to Select National Resource Inventory Conservation Practices, 2000-2012
This metadata record describes 26 30-meter raster data sets that estimate the percent of agricultural land that may be subject to select conservation practices for each year during the period 2000-2012. The data were derived from U.S. Department of Agriculture (USDA) National Resources Conservation Service (NRCS) National Resource Inventory (NRI). One set of rasters (denoted by the ICP prefix) rep
Archive of Chirp Subbottom Profile Data Collected in 2017 from the Louisiana Chenier Plain
Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys around the eastern and western Chenier Plain, Louisiana, in 2017. Data were collected under the Barrier Island Coastal Monitoring (BICM) program, an ongoing collaboration between the State of Louisiana Coastal Protection and Restoration Authority (CPRA), the Un
Baseline Coastal Oblique Aerial Photographs Collected from False Cape State Park, Virginia, to Myrtle Beach, South Carolina, May 6, 2008
The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On May 6, 2008, the USGS's NACCH project conducted an oblique ae
Groundwater-quality data in the Mojave Basin Shallow Aquifer Study Unit, 2018: Results from the California GAMA Priority Basin Project
The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies and 10 monitoring wells in San Bernardino County, California in 2018. The wells were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priorit
Pacific Sand Lance Energy Density, Length, and Age, Prince William Sound, Alaska, 2012-2016
This data set documents the age, length, dry mass energy density, and dry mass of age-0 and age-1 Pacific sand lance captured in Prince William Sound Alaska each July from 2012 to 2016. The analysis of this data was published in von Biela et al. 2019 (doi:10.3354/meps12891).
Influence of Glacier Runoff on Ecosystem Structure in Gulf of Alaska Fjords 2004-2011
Marine ecosystems respond to a range of habitat variability in coastal zones modified by glacial freshwater outflows, biophysical data were collected in three study regions that included four major glacial fjord systems around the Gulf of Alaska. A suite of geographic, oceanographic, nutrient and biological attributes were sampled at these three study regions during peak ice-melt season in summer.
Projected Seafloor Elevation Along the Florida Reef Tract From Deerfield Beach to Homestead, Florida-75 Years From 2014 Based on Historical Rates of Mean Elevation Change
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along the coast of Miami, FL.
Projected Seafloor Elevation Along the Florida Reef Tract From Deerfield Beach to Homestead, Florida-100 Years From 2014 Based on Historical Rates of Mean Elevation Change
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along the coast of Miami, FL.
Projected Seafloor Elevation Along the Florida Reef Tract From Deerfield Beach to Homestead, Florida-50 Years From 2014 Based on Historical Rates of Mean Elevation Change
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along the coast of Miami, FL.
Paleohydrologic reconstructions of water-year streamflow for 31 stream gaging sites in the Missouri River Basin with complete data for 1685 through 1977
Tree-ring reconstructions of water-year (Oct 1 through Sep 30th) flow for 31 gaging sites in Missouri River basin, with complete data for 1685 through 1977 (n = 293 water years). The complete 105 tree-ring reconstructions of streamflow used in the Nature Scientific Reports paper were obtained from various sources; 74 flow reconstructions were obtained from the web resource, TreeFlow (http://www.tr
