Frequency of forest change across the conterminous United States from 1985-2020 Frequency of forest change across the conterminous United States from 1985-2020
We summarized annual remote sensing land cover classifications from the U.S. Geological Survey Land Cover Monitoring, Assessment, and Projection (LCMAP) annual time series to characterize the frequency of forest change across the conterminous United States (CONUS) between 1985-2020. Data include a raster map of CONUS with pixel values representing the number of years in which it was...
Multibeam bathymetry and acoustic backscatter from the Alaskan region, Extended Continental Shelf Project, 2011 field season: Gulf of Alaska and Bering Sea Multibeam bathymetry and acoustic backscatter from the Alaskan region, Extended Continental Shelf Project, 2011 field season: Gulf of Alaska and Bering Sea
This publication releases swath bathymetry and backscatter datasets derived from multibeam bathymetric data acquired by the U.S. Geological Survey (USGS) on the R/V Marcus G. Langseth legs MGL1108 (transit) and MGL1109 in the Gulf of Alaska, and MGL1111 in the Bering Sea. Leg MGL1108 data were combined with leg MGL1109 data during processing. These data were acquired with a Kongsberg...
Creep rate models for California faults in the 2023 US National Seismic Hazard Model Creep rate models for California faults in the 2023 US National Seismic Hazard Model
Widespread surface creep is observed across a number of active faults included in the US National Seismic Hazard Model. In northern California, creep occurs on the central section of the San Andreas Fault, along the Hayward and Calaveras faults through the San Francisco Bay Area, and to the north coast region along the Maacama and Bartlett Springs faults. In southern California, creep is...
Surveys and Monitoring of Coastal Cactus Wren in Southern San Diego County (ver. 6.0, March 2026) Surveys and Monitoring of Coastal Cactus Wren in Southern San Diego County (ver. 6.0, March 2026)
Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status following 3 years of drought and determine the relationships between specific elements of habitat quality, food availability, and Cactus Wren productivity and survival. Surveys were...
U.S. Streamflow Drought During the Last Century: annual drought and low flow metrics, annual climate, and trends for the periods 1921-, 1951- and 1981-2020 (ver. 1.1, August 2025) U.S. Streamflow Drought During the Last Century: annual drought and low flow metrics, annual climate, and trends for the periods 1921-, 1951- and 1981-2020 (ver. 1.1, August 2025)
This dataset contains annual flow metrics quantifying drought and low streamflows for USGS GAGES-2 gages in the contiguous U.S. satisfying data completeness checks for the periods 1921-2020, 1951-2020, and 1981-2020. The dataset also contains annual climate variables from the USGS Monthly Water Balance Model (MWBM). The dataset provides trend analysis outputs for annual drought and low...
Electrical Conductance Maps of the Great Basin, USA Electrical Conductance Maps of the Great Basin, USA
Images of subsurface electrical conductivity are useful for locating fluids and other electrically conductive phases at depth in the Earth. This data release presents electrical conductance maps estimated from a 3D model of the Great Basin, USA, at five different depth ranges, spanning 2 to 200 km depth. Electrical conductance is the integration of electrical conductivity in a depth...
