Discharge measurements made in Bayou Heron and Bayou Middle, Grand Bay, Mississippi in January 2017 Discharge measurements made in Bayou Heron and Bayou Middle, Grand Bay, Mississippi in January 2017
Grand Bay, a 30-square-kilometer embayment of the Gulf of Mexico bordered by 20 square kilometers of salt marsh, is experiencing rapid lateral shoreline erosion at up to 5 meters per year. Determining whether the eroded sediment is exported to the deep ocean or imported via tidal channels and deposited on the marsh platform is critical to understanding the long-term response of the marsh...
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases
Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most...
Streamflow and water chemistry in the Tenaya Lake Basin, Yosemite National Park, California Streamflow and water chemistry in the Tenaya Lake Basin, Yosemite National Park, California
The Tenaya Lake Water Budget Study seeks to quantify and understand the water balance within the principal snow accumulation and runoff yielding zone in the Sierra Nevada Mountains. The Study operates stage sensors and data loggers to record Tenaya Lake inflows, water surface elevation, and outflow, with continuous annual data collection for the 21 square-kilometer watershed located in...
Initial Observations of Landslides triggered by the 2018 Anchorage, Alaska earthquake Initial Observations of Landslides triggered by the 2018 Anchorage, Alaska earthquake
This data release provides the locations of 43 landslides that occurred during the 2018 Anchorage, Alaska earthquake mapped from high-resolution lidar (1-m). Lidar data can be accessed via the Alaska Division of Geological and Geophysical Surveys elevation portal (https://elevation.alaska.gov). Each landslide is represented as a point corresponding to the approximate location of the mid...
Interferometric Synthetic Aperture Radar Data, Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California, 2014-19 Interferometric Synthetic Aperture Radar Data, Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California, 2014-19
Synthetic aperture radar (SAR) data from the European Space Agency's (ESA) Sentinel-1A satellite were acquired for this study from the Alaska Satellite Facility (ASF) and used to generate spatially detailed land-surface deformation maps (interferograms) for the Mojave River and Morongo groundwater basins during 2014–19 using InSAR methods.
Aerial Photogrammetry Data and Products of the North Carolina coast: 2018-10-06 to 2018-10-08, post-Hurricane Florence Aerial Photogrammetry Data and Products of the North Carolina coast: 2018-10-06 to 2018-10-08, post-Hurricane Florence
This data release presents structure-from-motion products derived from imagery taken along the North Carolina coast in response to storm events and the recovery process. USGS researchers use the aerial photogrammetry data and products to assess future coastal vulnerability, nesting habitats for wildlife, and provide data for hurricane impact models. This research is part of the Remote...
