Highway U.S. 1 in Florida, built on Coral Reefs. Here is a MPEG of the Animation. 2006 US1 Flyover of the Florida Keys 01:00:35:00  -   01:02:03:17
With the Landsat 7 data we can rigorously test hypotheses about how entire reef ecosystems form,-- says coral reef ecologist Bruce Hatcher of Dalhousie University--We no longer are limited to the observations we can collect by wandering around in small boats and sampling individual reefs to infer large-scale processes from a few samples. 2007 Coral Reef Flyover of the Florida Keys 01:02:18:00  -   01:04:11:10
These elegant whorls of color are atolls, enclosed coral reefs almost always surrounding a lagoon. Generally speaking, atolls are the products of volcanic islands that have eroded away. 2008 Landsat 7 Looks at Coral Reefs: (1 of 2) 01:04:27:00  -   01:04:57:29
Detailed images of reefs from nearly 900 locations around the world have been collected in the first year of the Landsat 7 mission. 2009 Landsat 7 Looks at Coral Reefs: (2 of 2) 01:05:13:00  -   01:05:43:17
But over time, while the surrounding ocean wears away the main body of the island, the coral ring remains. 2010 Landsat 7 Looks at Banks 01:05:58:00  -   01:06:34:22
Near infrared data 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. 2011 Landsat 7 Looks at Barriers 01:06:50:00  -   01:07:33:16
Located in tropical latitudes, the hard structures we know as coral are really the incremental build-ups of calcium carbonate deposited from the skeletal remains of these tiny colonial animals. 2012 Landsat 7 Looks at Pseudo Atolls 01:07:48:00  -   01:08:16:04
A final zoomed-out with with all datasets visible. 2005 SeaWiFS Multiresolution Animation with Annotations 01:08:35:00  -   01:09:57:00

*Please note: the SVS does not fulfill requests for copies of the tapes in our library. On some of our animation pages, there is a direct link to a video distribution service from which tapes, handled by the Public Affairs Office (PAO)/Goddard TV, including some of our animations may be ordered. General information on this service can be found here.
