Soil Water Balance Model of Upper Chehalis River Basin, Southwestern Washington
A Soil Water Balance model for the Upper Chehalis River basin in southwestern Washington.
Frullania nisquallensis Species Confirmation, Attu Island, Alaska, 2018
This dataset contains sampling, molecular methods, and partial tRNA-Leu DNA sequence information for three individual Frullania nisquallensis.
Fish and selected physical and chemical water-quality data for the U.S. Geological Survey Midwest Stream Quality Assessment
In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey National Water Quality Assessment and the U.S. Environmental Protection Agency National Rivers and Streams Assessment. One of the objectives of the RSQA, and thus the MSQA, is to characte
Post-Hurricane Gustav Coastal Oblique Aerial Photographs Collected from the Chandeleur Islands, Louisiana, to Isles Dernieres Barrier Islands Refuge, Louisiana, September 4, 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. Hurricane Gustav made landfall on the Louisiana coastline near C
Sediment macrofaunal composition, sediment grain size, and taxa functional traits of multiple deep-sea coral habitats in the Gulf of Mexico, 2009-2014
Deep-sea corals can create a highly complex, three-dimensional structure that facilitates sediment accumulation and influences adjacent sediment environments through altered hydrodynamic regimes. Infaunal communities adjacent to different coral types, including reef-building scleractinian corals and individual colonies of octocorals, are known to differ from background non-coral soft-sediment comm
Datasets for Trends in Water Quality of Selected Streams and Reservoirs used for Water Supply in the Triangle Area of North Carolina, 1989-2013
This U.S. Geological Survey Data Release contains the associated data described in the Scientific Investigations Report, "Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989-2013". Since 1989, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in the water-supply
Data Used to Characterize Peak Streamflows and Flood Inundation Resulting from Hurricane Harvey
In the immediate aftermath of Hurricane Harvey, the USGS and FEMA worked together to document the storm event in southeastern Texas and southwestern Louisiana. This data release contains the flood inundation polygons, flood-depth rasters, mapped boundaries, and high-water mark (HWM) locations for the selected river basins, coastal basins, and coastal areas that flooded in Texas and Louisiana.
Geochemistry of ore, host rock, and mine waste pile samples of iron oxide-apatite (IOA) deposits of the eastern Adirondack Highlands, New York, in relation to potential rare earth elements resources, 2016-2018
Thirty-four ore, twenty-nine mine waste, seven host rock, two pegmatite, and one slag sample were collected from iron oxide-apatite (IOA) mines in the eastern Adirondack Highlands near Mineville and Ticonderoga, New York, from March 2016 to August 2018. The waste pile samples included twenty-five samples collected from rubble-sized mine waste piles and four samples from processed tailings piles.
USGS Gulf Coast Petroleum Systems, and National and Global Oil and Gas Assessment Projects - U.S. Gulf Coast Downdip Paleogene Formations 2017 Assessment Unit Boundaries and Input-Data Forms
The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set o
Stable Isotopes of Silver Chub, Dreissenid mussels, and Hexagenia spp. Mayflies from Western Lake Erie, 2014
This table contains Carbon and Nitrogen stable isotope data for Silver Chub (Macrhybopsis storeriana), dreissenid mussels, and Hexagenia spp. mayflies from western Lake Erie in 2014. Samples were collected between May and September 2014 as part of both routine monitoring and a lake-wide coordinated monitoring effort. Silver Chub were collected in trawls; Hexagenia and Dreissenids were captured in
Diets of Silver Chub (Macrhybopsis storeriana) in western Lake Erie, 2014
Diet and estimated ages of Silver Chub (Macrhybopsis storeriana) collected by the US Geological Survey in western Lake Erie in 2014 are presented. Fish were frozen in the field at -20 C and dissected in the lab. Ages were estimated by one experienced biologist who estimated ages twice, then reconciled age estimates when the two age estimates differed. Diet taxa were enumerated, dried individually
Data for Frictional Properties and 3-D Stress Analysis of the Southern Alpine Fault, New Zealand (2013)
New Zealand's Alpine Fault (AF) ruptures quasi-periodically in large-magnitude earthquakes. Paleoseismological evidence suggests that about half of all recognized AF earthquakes terminated at the boundary between the Central and South Westland sections of the fault. There, fault geometry and the polarity of uplift change. The South Westland AF exhibits oblique-normal fault motion on a structure or
