On April 19, 2003, the satellite captured this image of African dust lingering over the Atlantic Ocean west of Ireland. Mixed with white streaks of clouds, a huge plume of African dust is blowing over the United Kingdom (left) in this image from the satellite on April 15, 2003. In the waters of the North Sea between the UK and Denmark (to the east), the water is swirling with color that could indicate a mixture of sediment and marine plant life.
