Data

The U.S. Geological Survey (USGS) worked in cooperation with the Federal Emergency Management Agency (FEMA) to document the August and September, 2017 Hurricane Harvey storm event in southeastern Texas and southwestern Louisiana. Hurricane Harvey was the most significant rainfall event in United States history in scope and rainfall totals since rainfall records began during the 1880s. From August

In May 2015, we acquired high-resolution seismic profiles near six strong motion instruments located in Napa and Solano Counties, California. These strong motion instruments recorded horizontal peak accelerations (PGAs) from 0.329g to 0.611g, which were among the highest recorded in the Napa area during the 24 August 2014 Mw 6.0 South Napa Earthquake. Our goal is to measure the seismic velocities

The U.S. Geological Survey (USGS) Geology, Geophysics and Geochemistry Science Center (GGGSC) collaborated with the USGS Data at Risk (DaR) team to preserve and release a subset of magnetotelluric data from the San Andreas Fault in Parkfield, California. The San Andreas Fault data were collected by the Branch of Geophysics, a precursor to the now GGGSC, between 1989 and 1994. The magnetotelluric d

The 1966-2017 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (primarily species, but also some races and unidentified species groupings). These data are collected annually during the breeding season, primarily June and May, along thousands of randomly established roadside survey routes in the United States and Canada. Routes

Dataset contains a polygon shapefile representing poultry houses in the Upper Choptank watershed in Queen Anne's County, Maryland, and Kent County, Delaware.

These datasets provide spatially-explicit estimates of the magnitude of giant sequoia foliage dieback along selected trail corridors in Sequoia and Kings Canyon national parks, California, from 2014 through 2017. They additionally provide giant sequoia tree-ring measurements, through the year 1989, for two locations in the Giant Forest grove, Sequoia National Park, California.

The Argon geochronology dataset was collected by Leah E. Morgan and Alexie Millikin in the Argon Geochronology Laboratory of the USGS in Denver, Colorado in 2016. The dataset contains full raw argon isotopic data. An additional dataset includes whole rock geochemistry data collected under contract with the Central Mineral and Environmental Resources Science Center, USGS Denver. These data sets wer

The point data file ("Soda Fire Point and Pasture Data (2016).Point Data.csv") includes 2016 vegetative cover values of exotic annual grass and perennial grass measured within three different types of plots for 75 pastures in the Soda Fire, which burned in 2015: 6m2 plot using a grid-point intercept photo software, SamplePoint (Booth et al. 2006), 1m2 quadrat using an unguided rapid ocular estimat

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 June 22-23, 2010, the USGS's NACCH project conducted an obliq

The Louisiana State Legislature created Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coa
