Landsat 7 Looks at Coral Reefs: (2 of 2)

Visualizations by Stuart A. Snodgrass Released on October 23, 2000

Detailed images of reefs from nearly 900 locations around the world have been collected in the first year of the Landsat 7 mission.

Reefs around the world are in ecological collapse, especially in the Florida Keys, — says Dustan.— We need to use remote sensing to help fight for their conservation.

Near infrared data instead makes some areas on the reef jump out in bright red relief. The near infrared band best gathers the electromagnetic signature of a thriving ecosystem.

Coral forms off shore from volcanic islands in tropical latitudes, developing a barrier reef thats separated by a growing lagoon.
