Underwater Photogrammetry Products of Looe Key, Florida From Images Acquired Using the SQUID-5 System in July 2022 Underwater Photogrammetry Products of Looe Key, Florida From Images Acquired Using the SQUID-5 System in July 2022
Underwater images were collected using a towed-surface vehicle with multiple downward-looking underwater cameras developed by the U.S. Geological Survey (USGS). The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The raw images and associated navigation data were collected at Looe key, a coral reef located within the...
Gridded Pre-2015 bathymetry data for Icy Bay and Taan Fiord, Alaska Gridded Pre-2015 bathymetry data for Icy Bay and Taan Fiord, Alaska
This data release provides a gridded compilation of bathymetry data collected prior to the 2015 landslide in Taan Fiord, the northeast arm of Icy Bay, Alaska. The data release consists of a 50-m grid, derived from ten prior surveys covering both Taan Fiord and Icy Bay.
Estimated crop irrigation water use withdrawals in Sacramento Valley Groundwater Basin, Arizona for 2023 Estimated crop irrigation water use withdrawals in Sacramento Valley Groundwater Basin, Arizona for 2023
Observations of irrigated agricultural land within the Sacramento Valley Groundwater Basin in Arizona. Crops were verified in situ once in 2023 on Sep 14th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the Sentinel2 imagery...
Estimated crop irrigation water use withdrawals in Butler Valley Groundwater Basin, Arizona for 2023 Estimated crop irrigation water use withdrawals in Butler Valley Groundwater Basin, Arizona for 2023
Observations of irrigated agricultural land within the Butler Valley Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification twice in 2023; crop verification occurred first on May 10th and again on Sept 28th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2023...
Daily baseflow specific conductance and daily baseflow discharge at selected sites within the Colorado River Basin for water years 1980-2022 Daily baseflow specific conductance and daily baseflow discharge at selected sites within the Colorado River Basin for water years 1980-2022
This data release contains two sets of estimated values at selected sites within the Colorado River Basin: 1) daily specific conductance at 143 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); and 2) daily baseflow discharge at 100 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022). The estimates of daily baseflow discharge will be used as input...
FUTURES v2: Status Quo Projections of Future Patterns of Urbanization Across the Conterminous United States from 2020 to 2100 FUTURES v2: Status Quo Projections of Future Patterns of Urbanization Across the Conterminous United States from 2020 to 2100
We simulated future patterns of urban growth using the FUTure Urban-Regional Environment Simulation (FUTURES; Meentemeyer et al., 2013) version 2 framework. FUTURES is an open source urban growth model designed to address the regional-scale ecological and environmental impacts of urbanization; it is one of the few land change models that explicitly captures the spatial structure of...
