This past winter’s unusually thick and widespread ice in Lake Superior has retreated with the arrival of spring. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Aqua satellite on April 8, 2003, shows ice relegated to inlets and a few places along the shores of Lakes Superior (center), Michigan (south) and Huron (southeast).
The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS? maximum spatial resolution of 250 meters.
