On July 28, 2005, the Aqua MODIS instrument took this picture of a delicate plume of volcanic ash drifting westward from the Soufriere Hills Volcano on Montserrat. Montserrat appears in the middle of the image. Surrounding the island are its neighbors, several of them ringed in bright blue-green. A few things can cause this color: coral reefs covered by shallow water, sediment, and phytoplankton. Toward the lower left corner of the image, the ocean appears lighter. This lighter color is caused by sunglint, the reflection of the sunís light into the satellite sensor.

Just a question... what does MODIS stand for?

Sorry if that sounds a little naive, I'm not much into these kinds of things...

Cool picture tlr http://www.tombraiderforums.com/images/smilies/thumb.gif . If this sort of thing interests you, I'd suggest you find out about NASAs Worldwind program. I think it's downloadable - but don't hold me to that :rolleyes: . It's basically a worldwide mapping system constructed from satellite photos, but it also incorporates videos, scientific data on a MASSIVE range of Earth-related topics...gorgeous http://www.tombraiderforums.com/images/smilies/thumb.gif . With it, you really can say 'I can see my house from here...' (no joke - I can see where a new road a mile away is! http://www.tombraiderforums.com/images/smilies/yikes.gif )
