    • 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

    Metadata Updated: August 23, 2025

    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 mosaics) used for the impairment classification and the Google Earth Engine code used to build the raster mosaics.
