Geospatial Fabric for the National Hydrologic Model Alaska Domain, version 1 Geospatial Fabric for the National Hydrologic Model Alaska Domain, version 1
This metadata record documents a geospatial dataset for the U.S. Geological Survey Precipitation Runoff Modeling System (PRMS) used to drive the National Hydrologic Model (NHM). The Alaska Geospatial Fabric v1 is the spatial representation of the hydrologic response units (HRUs) used for the PRMS NHM Alaska domain. These HRUs were generated using the twelve-digit Hydrologic Unit Code...
Digitized Historical Borehole Geophysical Logs Throughout the Mississippi Alluvial Plain Aquifer System Digitized Historical Borehole Geophysical Logs Throughout the Mississippi Alluvial Plain Aquifer System
This data release consists of historical borehole geophysical data collected by various entities and digitally recreated by the U.S. Geological Survey to characterize the physical properties of the subsurface in the Mississippi Alluvial Plain from Louisiana to Missouri. The geophysical log data were collected by different Federal, state, and local agencies throughout the area, and were...
Occurrence of Polycyclic Aromatic Hydrocarbons Associated with Coal-Tar Based Pavement Sealant Related PAHs in Urban Sediments in Maine Occurrence of Polycyclic Aromatic Hydrocarbons Associated with Coal-Tar Based Pavement Sealant Related PAHs in Urban Sediments in Maine
The dataset includes results from the analysis of sediments and solids collected from receptor sites receiving runoff from adjacent parking lots and other paved surfaces. Receptor sites include parking lot catch basins, retention ponds, drainage ditches, and storm-water discharge zones in streams and rivers. Samples were analyzed for percent moisture content and concentrations of 17 U.S
Slope Values Across Marsh-Forest Boundary in Chesapeake Bay Region, USA Slope Values Across Marsh-Forest Boundary in Chesapeake Bay Region, USA
The marsh-forest boundary in the Chesapeake Bay was determined by geoprocessing high-resolution (1 square meter) land use and land cover data sets. Perpendicular transects were cast at standard intervals (30 meters) along the boundary within a GIS by repurposing the Digital Shoreline Analysis System (DSAS) Version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. Average...
Annual Management Unit Summary Code Annual Management Unit Summary Code
The Phragmites Adaptive Management Framework (PAMF) is an adaptive management program created to improve the efficacy and efficiency of Phragmites management efforts throughout the Great Lakes region. Managers enroll Phragmites stands, report the management techniques they used, and monitor the invasion status of Phragmites on their site (management unit - MU). Through a systematic...
Data to accompany U.S. Geological Survey Fact Sheet 2020-3017: Pyrrhotite distribution in the conterminous United States Data to accompany U.S. Geological Survey Fact Sheet 2020-3017: Pyrrhotite distribution in the conterminous United States
The mineral pyrrhotite, which is an unstable sulfide mineral, was present in crushed stone aggregate used in concrete foundations of homes in Connecticut and Massachusetts, many of those foundations are failing as the mineral weathers. Because of the substantial costs of lifting homes and replacing their foundations, in 2019 the U.S. Congress directed the U.S. Geological Survey?s (USGS)...
