Data

This USGS data release presents historic shorelines of Lake Superior near Odanah, Wisconsin encompassing the delta complex of the Bad River from 1852 to 2013 compiled in a Geographic Information System. The coverage of the shorelines starts approximately 8 km northeast of Ashland and extends for about 40 km to approximately 3 km east of the Bad River mouth. The shorelines were derived...

Prescribed burning is a critical tool for managing wildfire risks and meeting ecological objectives, but its safe and effective application requires that specific meteorological criteria are met. This dataset contains results from a study examining the potential impacts of projected climatic change on prescribed burning in the southeastern United States. A set of burn window criteria...

The North Dakota State Water Commission and International Joint Commission partnered with USGS to characterize the climate and streamflow in the Souris River Basin and develop a set of daily streamflow traces from 10-day stochastic streamflow traces discussed in Kolars and others (2016).The Kolars and others (2016) dataset is provided and was used to determine the statistical...

This digital dataset includes 255 samples from 41 groundwater wells and 271 samples of produced water from 143 sites (including 101 wells) located within 3 miles of the San Ardo Oil Field in Monterey County, central California. Historical geochemistry data were compiled from multiple data sources for selected water-quality indicators, major and minor ions, nutrients, and trace elements...

Ice breakup dates of Chequamegon Bay, Lake Superior from 1911 to 2022 were compiled by Lori Evrard (USGS, GLSC, Lake Superior Biological Station, Ashland, WI). Ice breakup date is the day in spring when winter ice cover substantially leaves a water body. Local residents deem "ice breakup" as when the ice moves northeast of a line straight across Chequamegon Bay out from Ellis Avenue...

This data set provides a table of length, weight, sex, and estimated fecundity of Silver Chub Macrhybopsis storeriana in western Lake Erie from 1979 through 1987. These data are potentially useful to those studying recovery and restoration of Silver Chub in Lake Erie. These data were collected as part of routine trawl surveys in western Lake Erie. Other data associated with these data...

This dataset contains geochemical and other information for 40 historical samples of produced water from the North Coles Levee Oil Field. Three of these samples are from commingled tanks containing produced water from multiple wells as noted in the Remarks column. Water that is produced as a byproduct of oil production is called produced water. The numerical water chemistry data were...

A suite of morphological metrics were derived from existing shoreline and elevation datasets for barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. This dataset includes barrier shorelines and polygons attributed with morphological metrics from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s.

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photograph or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the Digital Shoreline Analysis System software (v5.1) to compute their rates of change...

The U.S. Geological Survey (USGS) compiled data from a variety of national and state agencies to create a comprehensive dataset of streamflow and stage for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California. Seasonal maximum values were calculated for streamflow and stage for the winter (November-March) and spring (April-July) flow seasons, as...

These data represent key phenology trends across the western United States from 1982-2016. Using two remote sensing datasets, CMGLSP and VIPPHEN-EVI2, trends were calculated for four phenology variables: Start of Season (SOS), Peak Instantaneous Rate of Green-Up Date (PIRGd), Peak of Season (POS), and End of Season (EOS). The Theil-Sen slope and standard deviation were applied to the...

In October and November of 2016 and 2017, the U.S. Geological Survey collected horizontal-to-vertical spectral ratio (HVSR) data at 104 sites in the Genesee Valley, Livingston County, New York as part of a saline-groundwater investigation in cooperation with the New York State Department of Environmental Resources. The HVSR technique, commonly referred to as the passive-seismic method...
