Latest Unique Imagery Events

* Unique Imagery: Storm-Churned waters off Cuba
Gustav may have spared the United States from the destruction that many feared, but it hit Cuba hard. 1 Image, Posted: September 02, 2008
* Unique Imagery: Phytoplankton Bloom in the Barents Sea
The waters of the Barents Sea off the northeast coast of Norway were bright with a bloom of phytoplankton on August 12, 2008. 1 Image, Posted: August 19, 2008
* Unique Imagery: Algae Along the Coast of China

* Unique Imagery: Melt Season along the Greenland West Coast
In late June 2008, melt season had begun along the west coast of Greenland. 1 Image, Posted: July 02, 2008
* Unique Imagery: Heatwave in Northern Europe
On the calendar, Scandinavian summer starts on June 21 in 2008, but summer temperatures had already settled over much of northern Europe by early June. 1 Image, Posted: June 20, 2008
* Unique Imagery: Earthquake Near Chengdu, China
On May 12, 2008, an earthquake with an estimated magnitude of 7.9 struck China's Sichuan Province. Aftershocks, some of them larger than magnitude 6.0, continued in the weeks after the quake. Large lakes formed behind landslide-created dams. 11 Images, Updated: June 10, 2008
* Unique Imagery: Glory Over Pacific Ocean Clouds
On May 20, 2008, a deck of clouds over the Pacific Ocean provided an optical display for the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. The ring-shaped, rainbow-like phenomenon, known as a "glory," appears through the length of the center of this image. 1 Image, Posted: May 29, 2008
* Unique Imagery: Spring in Kazakhstan
Melting ice and an upsurge of agricultural fires revealed that spring was settling over southern Kazakhstan by March 30, 2008. 1 Image, Posted: April 02, 2008
* Unique Imagery: Ship Tracks off British Columbia
Streaky clouds called ship tracks formed over the Pacific Ocean west of Canada's British Columbia province on January 21, 2008. 1 Image, Posted: January 24, 2008
* Unique Imagery: Phytoplankton surround the Falkland Islands
Millions of tiny ocean plants ringed the Falkland Islands in early January 2008. 1 Image, Posted: January 15, 2008
