EAARL Coastal Topography-Dauphin Island, Post-Hurricane Katrina, 2005
These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for Dauphin Island, Alabama. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) during September 2005, immediately following Hurricane Katrina landfall.
Walrus Bayesian State-space Model Output from the Bering Sea and Chukchi Sea, 2008-2012
State-space models offer researchers an objective approach to modeling complex animal location datasets, and state-space model behavior classifications are often assumed to have a link to animal behavior. We evaluated the behavioral classification accuracy of a Bayesian state-space model in Pacific walruses using Argos satellite tags outfitted with sensors to detect animal behavior in real time. S
EAARL Coastal Topography-Dauphin Island, 2010
These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for Dauphin Island, Alabama. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on July 24, 2010, one day before remnants from the dissipated Tropical Storm Bonnie came ashore.
Precipitation, surface-water discharge, and groundwater elevation data for Fourmile Creek, Ankeny, Iowa, USA during October 1, 2013 to November 30, 2013
Dataset includes continuous discharge at the USGS (Station ID: 05485605) Fourmile Creek near Ankeny, IA DS1 gage site (http://waterdata.usgs.gov/usa/nwis/uv?site_no=05485605) as well as daily precipitation and water level data in select groundwater piezometers recorded in 10 minute intervals during the period Oct 1, 2013 to November 30 2013. Latitude and longitude data are provided for groundwater
Total Mercury Concentrations in Fish Muscle from the Colorado River and Bright Angel Creek, AZ, USA (2015)
Mercury is a globally distributed pollutant that threatens human and ecosystem health. Even protected areas, such as national parks, are subjected to mercury contamination because it is delivered via atmospheric deposition, often after long-range transport. In aquatic ecosystems, certain environmental conditions can promote microbial processes that convert inorganic mercury to an organic form (met
Sea Level Rise Animation
The animations are not a prediction of sea level rise, but rather illustrate areas of low elevation by a blue color simulating coverage by water. The numbers of people in those areas are tabulated.
Wisconsin Real-Time Groundwater-Level Network
The Real-Time Groundwater Level Network contains data typically recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. All real-time data are provisional and subject to revision.
Estimates of Subsurface Tile Drainage Extent for 12 Midwest States, 2012
This dataset is a 30-meter resolution raster of estimated extent of subsurface tile drainage developed from tabular data of state-level estimates of agricultural land drained by tiles combined with geospatial cropland and soils in 12 Midwest States (SD,NE, KS, MN, IA, MO, WI, IL, MI, IN, OH, and KY). This dataset was created from the following four sources: 1) state-level acreages of agricultural
Langelier Saturation Indices Computed for U.S. Groundwater, 1991-2015; Water Well Data and Characteristic Values for States
The occurrence of metals, such as lead and copper, in household drinking supplies can often be a result of the corrosion of pipes and joints in water distribution systems. One measure of the potential for water to cause corrosion is the Langelier Saturation Index (LSI) (Langelier, 1936). The LSI is a measure of the potential for water to deposit a mineral layer (scale) within a water distribution
Hurricane Sandy washover deposit data from southern Long Beach Island, New Jersey: Grain-size, elevations, and graphic core logs
Sedimentologic and topographic data from Hurricane Sandy washover deposits were collected from Southern Long Beach Island, New Jersey, in order to document changes to the barrier-island beaches, dunes, and coastal wetlands due to Hurricane Sandy and subsequent storm events. These data will provide a baseline dataset for use in future coastal change descriptive and predictive studies and assessment
Topobathymetric Lidar Survey of Breton and Gosier Islands, Louisiana, January 16 and 18, 2014
This dataset contains binary point-cloud data and a Digital Elevation Model (DEM), produced from remotely sensed, geographically referenced topobathymetric measurements encompassing the Breton Island and Gosier Islands, LA study area. The original area of interest was buffered by 100 meters to ensure complete coverage, resulting in approximately 75 square miles of lidar data.
The Breton Island Li
Estuarine Shoreline and Barrier-Island Sandline Change Assessment
The Barrier Island and Estuarine Wetland Physical Change Assessment Dataset was created to calibrate and test probability models of barrier island sandline and estuarine shoreline change for study areas in Virginia, Maryland, and New Jersey. The models examined the influence of hydrologic and physical variables related to storm-derived overwash and estuarine shoreline change. Variables were calcul
