Data

These datasets contain the attributes of individual trees located in and around Sequoia and Kings Canyon national parks. Attributes include remote sensing indices, terrain characteristics, and-- for the calibration data-- tree size and growth rates. Calibration data (mixedconifervulnerability_calibrationdataset.csv) were collected in long term research plots where trees are visited...

This data release contains mean high water (MHW) shorelines along the coast of California for the years 1998/2002, 2015, and 2016, extracted from Light Detection and Ranging (LiDAR) digital elevation models using ArcGIS. The Digital Shoreline Analysis System (DSAS) was used to calculate net shoreline movement (NSM) between the pre-El Nino (2015) and post-El Nino (2016) shorelines, as a...

Wildfires pose significant threat in an increasingly arid California landscape, threatening life, property, and air quality, and having long-term impacts on the state's water. Knowing the location and extent of wildfires may help scientists and resource managers predict and manage potential impacts burns may have upon California's water quality, availability, and movement.

This dataset includes raw and rinex data from 2020 campaign gps data from the Island of Hawai`i in 2020. There was a total of 57 sites occupied. All data are included along with metadata, log sheets and raw/rinex data.

This data set provides capture information and body size measurements of adult and gosling Greater White-fronted Geese captured at three study sites on the Arctic Coastal Plain of Alaska, 2012-2014.

This dataset contains information from capture-mark-recapture sampling of Oregon spotted frogs (Rana pretiosa) conducted 2016-2019 by USGS as part of a study relating R. pretiosa survival and abundance to wetland inundation in the upper Deschutes River. Data consist of site, survey, habitat, and species detection covariates, as well as 10 years of hydrological and drought metrics used to...

This dataset includes carbon and nitrogen isotope concentrations measured in polar bear hair and marine mammal prey samples collected 1978-2017 in the Beaufort and Chukchi Seas. Marine mammal prey samples were collected opportunistically either from polar bear seal kill sites or from marine mammals harvested by Native hunters. Hair was collected from polar bears captured on the sea ice...

Animal identification number, weight in grams for carcasses of California tiger salamanders (Ambystoma californiense) CTS and Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum) SCLT from Prospect or Ellicott Pond, on Ellicott Slough National Wildlife Refuge, California U.S.A. submitted to U.S. Geological Survey, National Wildlife Health Center (NWHC) for determination of...

This product is a media player application and user guide. The application generates set-interval and random-interval media play schedules. When the application is used to execute the play schedule, it creates its own metadata documentation. The Carp Media Player documents the intended play schedule, generates a real-time log of the media played, and documents if there were any...

This data release presents catch and effort data for Cisco Coregonus artedi and Lake Whitefish Coregonus clupeaformis commercial gill net fisheries in State of Michigan waters of Lakes Superior, Michigan, and Huron during 1929-1970. The data were used to determine if Cisco and Lake Whitefish relative abundance (commercial gill net catch per effort) were correlated (positive and negative)...

Green Peter Dam on the Middle Santiam River and the downstream Foster Dam on the South Santiam River in Oregon have altered natural seasonal temperature patterns in those rivers. In response, the U.S. Army Corps of Engineers is leading efforts to improve conditions for Chinook salmon upstream and downstream of these dams by considering structural alterations and by exploring changes to...

In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 15 cores or outcrops from the Gulf Coastal Plain (Alabama, Mississippi, and Georgia). Samples have been assigned a USGS sample number and are organized by depth below (cores and wells) or height above (outcrops) the land surface. Based on their known stratigraphic...
