Historical Extent of Metal Mobilization Within Dolly Varden (Salvelinus malma) Spawning Habitat of the Noatak River Drainage Based on Landsat and Sentinel Data, 1986-2024 Historical Extent of Metal Mobilization Within Dolly Varden (Salvelinus malma) Spawning Habitat of the Noatak River Drainage Based on Landsat and Sentinel Data, 1986-2024
This data release provides a vector geospatial shapefile of river and creek segments within Dolly Varden (Salvelinus malma) habitat in the Noatak River drainage (DeCicco 1985) classified for metal impairment between 1986 and 2024. The impairment classifications were based on visual inspection of Landsat and Sentinel satellite imagery. Also provided are the satellite images (as raster...
Estimated crop irrigation water use withdrawals in Gila Bend Groundwater Basin, Arizona for 2024 Estimated crop irrigation water use withdrawals in Gila Bend Groundwater Basin, Arizona for 2024
Observations of irrigated agricultural land within the Gila Bend Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 8th and again on Aug 27th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the...
MODFLOW-2005 Groundwater Flow Model Used to Simulate Wastewater-Return-Flow Scenarios in Falmouth, Massachusetts MODFLOW-2005 Groundwater Flow Model Used to Simulate Wastewater-Return-Flow Scenarios in Falmouth, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Town of Falmouth, used an existing groundwater flow model to simulate responses of the freshwater hydrologic system in Falmouth, Massachusetts to proposed wastewater-return-flow scenarios. The existing model is a steady-state, three-dimensional MODFLOW-2005 model of the Sagamore flow lens of the Cape Cod aquifer documented by...
Landsat-based Illustrative implementation of Satellite Psychrometry for ET Mapping Landsat-based Illustrative implementation of Satellite Psychrometry for ET Mapping
Remote sensing-based evapotranspiration (ET) can be derived using various methods, from soil moisture accounting to vegetation-index based approaches to simple and complex surface energy balance techniques. Due to the complexity of fully representing and parameterizing ET sub-processes, different models tend to diverge in their estimations. However, most models appear to provide...

Estimated Current and Future Community Suitability of Pinyon and Juniper Woodlands for 3 Emissions Scenario Pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) and Bivariate Comparisons Across Western North America Estimated Current and Future Community Suitability of Pinyon and Juniper Woodlands for 3 Emissions Scenario Pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) and Bivariate Comparisons Across Western North America
These data consist of gridded projected pinyon-juniper community-level suitability values across western North America. The objectives of our study were to estimate community-level suitability for pinyon-juniper woodlands under current and future climate conditions and compare geographic patterns in suitability against additional management considerations, such as burn probability and...
