They also hope to better understand the link between visible habitats and the cryptic biocomponent (the hidden worms, crabs, clams and brittlestars) that comprise the bulk of diversity on the reef.

Today, scientists see essentially what you're seeing: pretty colors and snapshot maps of islands and ocean. Marine biologists who want to know the distribution and health of species inhabiting a coral reef can't rely on these remote images, however. They need to put on mask and fins and do some snooping around.

Not for long, perhaps.

Remote imaging and its promising potential for scientists and environmentalists is something we'll delve into during the coming weeks as part of our live storytelling from the reef. For now, use your mouse to see the satellite images scientists are working with today. You can drill down from this space-based image of the Bahamas (the Andros study area is outlined in red) until you actually enter the water near the Andros Reef.
