Probably because of the severe storms that passed through the area on the previous day, the Gulf Coast waters off Florida were churned up and cloudy when the Aqua satellite passed overhead on November 20, 2003. The Moderate Resolution Imaging Spectroradiometer (MODIS) captured this image of the state of Florida in the southeast United States and the waters of the Gulf of Mexico (left) and the Atlantic Ocean (right) after the storms had passed through. The turbid (cloudy) waters could be caused by a mixture of sediment churned up by wave action, increased runoff of sediment and organic matter from rivers and streams, and ocean plant life.
The turquoise-colored waters surrounding the Bahamas Islands at lower right are that color all the time; the shallow waters around the island shelf reflect more sunlight than do the deeper waters of the Atlantic that surround them. Even here, however, some of the added cloudiness may be due to the passing storms.
On land, the swamps of the Everglades give the tip of Florida a purplish color, with the West Palm Beach-Fort Lauderdale-Miami megalopolis crowds up against them on the east in a concrete-colored line. A few smoke plumes are drifting out over the Gulf from fires in western Florida.
Soft shades of turquoise and tan color the waters of the Gulf of Alaska and Prince William Sound in this photo-like image captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on March 13, 2008. Though the swirls may look delicate from space, they hint at an ocean in turmoil. Strong winds and high waves likely churned the ocean, bringing sediment to the surface in the shallow waters over the continental shelf. The deeper waters beyond the shelf edge in the lower right corner of the image are dark blue, not clouded by sediment.
