A mid-November dust storm continued to pour glacial sediment over the Gulf of Alaska on the afternoon of November 16, 2013. The Moderate Resolution Imaging Spectroradiometer aboard the Aqua satellite captured this true-color image at 2240 UTC (5:50 p.m. EST).

A plume of gray sediment rises from the Copper River Valley, located near the center of the image. This plume widens and thins as it crosses the Gulf of Alaska. Underneath this plume the sediment, arising either from runoff or from the blowing dust, turns the waters green and turquoise.

A narrower plume rises from the terminus of the Bering Glacier. It first blows to the southwest, but as it encounters strong winds over open water it curves abruptly to the southeast. Glacial dust can also be seen aloft inland, near the top right of the image.

This storm was captured earlier in the day by the MODIS on the Terra satellite, and that image appeared as the Image of the Day on November 24. To compare the changes in the day, that image can be viewed here: http://modis.gsfc.nasa.gov/gallery/individual.php?db_date=2013-11-24.
