Estimates of Iron Mineralization in Select Reaches of Three Alaska Arctic Rivers Derived from Historical Landsat Imagery Estimates of Iron Mineralization in Select Reaches of Three Alaska Arctic Rivers Derived from Historical Landsat Imagery
These data are in three tables each reporting estimated iron mineralization within stream reaches from three arctic rivers in northwestern Alaska on select days between July-August, 1985-2022. The relative magnitude of iron mineralization was measured using a remotely sensed iron index calculated from available Level 2, Collection 2, Tier 1 Landsat Surface Reflectance products derived by...
LEAP: Landsat Extended Acquisitions of the Poles Imaging Plan LEAP: Landsat Extended Acquisitions of the Poles Imaging Plan
Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These...
Long-term water-quality trends for rivers and streams within the contiguous United States using Weighted Regressions on Time, Discharge, and Season (WRTDS) (ver. 1.1, March 2025) Long-term water-quality trends for rivers and streams within the contiguous United States using Weighted Regressions on Time, Discharge, and Season (WRTDS) (ver. 1.1, March 2025)
The U.S. Geological Survey (USGS) Water Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand. It is also improving understanding of the natural and human factors affecting the balance between supply and demand. A key...
Four Mile Canal Terracing and Sediment Trapping (TV-18): 2015 and 2018 land-water classifications Four Mile Canal Terracing and Sediment Trapping (TV-18): 2015 and 2018 land-water classifications
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
