    “This tool visualizes near real-time (NRT) satellite-based fire perimeters, active portions of fire perimeters (fire lines), and active fire pixel detections for the current year.
    Use the bottom panel to select different date ranges or subset fires by size, duration, or intensity. Click on an individual fire to visualize the time series of fire growth every 12 hours and create video outputs in GIF or WebM formats.
    These fire tracking data are from the Fire Event Data Suite (FEDS) algorithm. Find out more:
    • FEDS data source documentation
    • OpenVEDA documentation
    • Earthdata VEDA dashboard..."

    “... KEY POINTS:
    • River meandering resets permafrost development and vegetation succession by eroding old floodplain areas and depositing new land
    • On the Koyukuk River, permafrost rapidly forms in new deposits, but it takes over 4 Kyr to develop to its full areal extent of 85%
    • The rate of permafrost formation is likely linked to vegetation succession on younger and overbank deposition on older floodplain areas…”

    "This coloring book was assembled using high resolution topography data from the United States Geological Survey’s 3D Elevation Program to create detailed contour maps for each US State and the District of Columbia.
    Each State's contour interval (the vertical distance between elevation lines on a map) was selected to preserve the topographic details the State’s inhabitants know and love. Specifically major mountain ranges and river valleys."
