Locations Collected 1985-2015 from Female Polar Bears (Ursus maritimus) with Dependent Young Instrumented in the Southern Beaufort Sea with Satellite-linked Transmitters by the USGS Locations Collected 1985-2015 from Female Polar Bears (Ursus maritimus) with Dependent Young Instrumented in the Southern Beaufort Sea with Satellite-linked Transmitters by the USGS
This dataset contains a select subset of Argos and GPS locations collected by satellite data collection systems from collared adult female polar bears that were instrumented in the southern Beaufort Sea between 1985-2015.
Loch Lomond Reservoir 2019 Survey Data Loch Lomond Reservoir 2019 Survey Data
This dataset contains the digital elevation model from the bathymetric survey, along with the sediment samples, stage-area table, stage-storage table, and 20-ft contours of the reservoir.
Long term cone production of white spruce throughout boreal forests in North America Long term cone production of white spruce throughout boreal forests in North America
Data were compiled on the seed production of white spruce in order to assess the long-term trends in seed production over the past 60 years in North American boreal forests. Data on cone production was merged with annual weather, teleconnection indices such as ENSO, and historical fires in boreal forests.
Long-term field observation of shrubland ecosystem in Wyoming, USA from 2008-2018 Long-term field observation of shrubland ecosystem in Wyoming, USA from 2008-2018
The importance of monitoring shrublands to detect and understand changes through time is increasingly recognized as critical to management. This dataset focuses on ecological change observation over ten years of field observation at 134 plots within two sites that are located in Southwestern of Wyoming, USA from 2008-2018. At sites 1 and 3, 134 long-term field observation plots were...
Long-term hydrological and biological data from Williams and Shingobee Lakes, north-central Minnesota Long-term hydrological and biological data from Williams and Shingobee Lakes, north-central Minnesota
The Shingobee Headwaters Aquatic Ecosystem Project is a long-term, multi-disciplinary monitoring and research study of a 28-square-kilometer headwaters watershed in north-central Minnesota that began in 1978. Emphasis is on processes related to hydrology, limnology, geochemistry, and watershed ecology and the land-water and atmosphere-water interfaces. Lakes are a substantial focus and...
Long-term sandbar monitoring data along the Colorado River in Marble and Grand Canyons, Arizona (ver. 2.0, March 2026) Long-term sandbar monitoring data along the Colorado River in Marble and Grand Canyons, Arizona (ver. 2.0, March 2026)
This data release comprises nearly three decades of measurements of sandbar topography for monitoring sites along the Colorado River in Grand Canyon National Park and Glen Canyon National Recreation Area. The data were collected to monitor the effects of the operations of Glen Canyon Dam on sandbars, which are also recreational campsites. The data were collected by the US Geological...
Long-Term Site Potential Rangeland Fractional Component Cover and Deviation in Wyoming, USA Long-Term Site Potential Rangeland Fractional Component Cover and Deviation in Wyoming, USA
Monitoring rangelands by identifying the departure of contemporary conditions from long-term ecological potential allows for the disentanglement of natural biophysical gradients driving change from changes due to land uses and other disturbance types. We developed maps of ecological potential (EP) for shrub, sagebrush (Artemisia spp.), perennial herbaceous, litter, and bare ground...
Lotic vs. Lentic Water: a U.S. national 30-meter raster classification of water areas by velocity Lotic vs. Lentic Water: a U.S. national 30-meter raster classification of water areas by velocity
This dataset consists of a national 30-meter raster which classifies pixels representing water from the National Land Cover Database 2016 (NLCD 2016) according to their estimated velocity regime. At the broadest classification, the data are mapped into two groups: "Lentic", representing water bodies such as lakes, ponds, oceans, and bays, and "Lotic", representing flowing water, such as...
