Inventory Data of Lowland-Breeding Birds and Associated Vegetation Types on the Alaska Peninsula, 2004-2007 Inventory Data of Lowland-Breeding Birds and Associated Vegetation Types on the Alaska Peninsula, 2004-2007
This release includes data collected using stratified random surveys to inventory the birds breeding in lowlands (elevation below 100m) of the Alaska Peninsula, during summers 2004-2007. Data were collected at 792 survey points (10-minute point counts) on 52 5-km x 5-km plots. The data are in seven tables: 1) geographic coordinates of the bounding corners of each of the 52 survey plots...
Archive of Chirp Subbottom Profile and Single-Beam Bathymetry Data Collected in 2021 From Santa Rosa Island, Florida Archive of Chirp Subbottom Profile and Single-Beam Bathymetry Data Collected in 2021 From Santa Rosa Island, Florida
As part of the Coastal Resource Evaluation for Management Applications (CREMA) Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and determine Holocene stratigraphy near Pensacola Beach, Florida (FL) in June of 2021. The objective of the project is to...
covMRVAgen1, Source code for construction of covariates bound to monthly groundwater levels for purposes of statistical modeling of water levels in the Mississippi River Valley alluvial aquifer covMRVAgen1, Source code for construction of covariates bound to monthly groundwater levels for purposes of statistical modeling of water levels in the Mississippi River Valley alluvial aquifer
The covMRVAgen1 repository contains R (primarily), Mermaid, Perl, and Python language source code that can be used the construction of input tables of monthly groundwater levels (response variable) and predictor variables (covariates) for statistical modeling of water levels in the Mississippi River Valley alluvial aquifer within the Mississippi Alluvial Plain, south-central United...
Digital elevation models (DEMs) and field measurements of flow velocity used to develop and test a multidimensional hydrodynamic model for a reach of the upper Sacramento River in northern California Digital elevation models (DEMs) and field measurements of flow velocity used to develop and test a multidimensional hydrodynamic model for a reach of the upper Sacramento River in northern California
This data release includes the input topographic data sets, model parameters, and validation field measurements of flow velocity used to develop and test multidimensional hydraulic models for a reach of the upper Sacramento River in northern California. Digital elevation models (DEMs) were developed by combining water depth maps of the reach, created using spectrally-based remote sensing...
Data Release for Luminescence: Mid to Late Quaternary Geomorphic and Paleoseismic Event History, Cheraw Fault, Colorado Data Release for Luminescence: Mid to Late Quaternary Geomorphic and Paleoseismic Event History, Cheraw Fault, Colorado
Despite its subdued expression and isolated location within the Great Plains of southeastern Colorado, the 80-km-long Cheraw fault may be one of the most active faults in North America east of the Southern Rocky Mountains. We present geomorphic analyses, geochronology, and paleoseismic trenching data to 1) document the rupture history of the ~45-km-long southwestern section of the Cheraw...
Data Release for Luminescence: Luminescence data for Natural Trap Cave, Wyoming Data Release for Luminescence: Luminescence data for Natural Trap Cave, Wyoming
The following report summarizes the dating results from the Natural Trap Cave 2018-2019 dating project. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included...
Data Release for Luminescence: Floodplain Sediment Storage Timescales of the Laterally Confined Meandering Powder River, U.S.A Data Release for Luminescence: Floodplain Sediment Storage Timescales of the Laterally Confined Meandering Powder River, U.S.A
The following report summarizes the dating results from the. Within this report, we detail the methodology used to determine the storage time distribution for a 17 km length of Powder River in Montana, U.S.A. by the age distribution of eroded sediment. This data is used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence...

nshm-conus-v5 nshm-conus-v5
National Seismic Hazard Model (NSHM) for the conterminous U.S. This model is intended for use with U.S. Geological Survey (USGS) hazard software nshmp-haz. This model was last updated in 2018.
nshm-hawaii-v2 nshm-hawaii-v2
National Seismic Hazard Model (NSHM) for the State of Hawaii. This model is intended for use with U.S. Geological Survey (USGS) hazard software nshmp-haz.
nshmp-haz-v2 nshmp-haz-v2
U.S. Geological Survey (USGS) National Seismic Hazard Model Project (NSHMP) codes for performing probabilistic seismic hazard (PSHA) and related analyses. These codes are intended for use with seismic hazard models developed by the NSHMP for the U.S. and its territories. This project includes a variety of command line applications and web service classes and relies on the nshmp-lib...
nshmp-lib nshmp-lib
nshmp-lib is a USGS developed Java library that supports probabilistic seismic hazard (PSHA) and related analyses. This project includes all the code required to load, process and query USGS National Seismic Hazard Models (NSHMs). nshmp-lib is used by command line applications and web services found in the nshmp-haz project. See that project for running PSHA calculations.
