- 2008 Arctic Sea Ice Concentration Map
-- Using the latest satellite observations from early 2008, NASA
researchers and others report that the Arctic is still on 'thin ice'
when it comes to the condition of sea ice cover in the region. This ice
concentration map from March 9, 2008, shows maximum extent of sea ice
in the Northern Hemisphere.
- Arctic Sea Ice Distribution by Age
-- The sea ice in the Arctic is much younger than normal, with vast
regions now covered by first-year ice. The left image shows February
distribution of ice by its age during normal Arctic conditions
(1985-2000 average), and the right illustrates February 2008 Arctic ice
- Algae Bloom in Antarctic Sea Ice
-- It was late summer 2007 in the Southern Hemisphere when NASA's Aqua
satellite captured this image of Antarctica's Ross Sea (left). The
image reveals a subtler sign of the growing season: The yellowish-green
tinge of some of the sea ice is probably a bloom of algae.
- Mega-iceberg A53a, South Atlantic
-- Astronauts captured images of this massive iceberg from the
International Space Station on Jan. 18, 2008. At the time, the iceberg
was in the Atlantic Ocean some distance from Tierra Del Fuego in South
America. Glaciologists think this iceberg is fast approaching the point
of breaking up.
- Cloud Streets Across Caspian Sea
-- South of the loosely packed ice in the northern part of the sea,
parallel rows of clouds line up along the north-south axis of the wind.
These clouds form when cold air blows over the warmer, moister air that
sits over the water.
- Robert Bindschadler's Antarctic Blog
-- NASA's Robert Bindschadler wrote a blog during his latest trip to
Antarctica on a quest to carry out experiments at Pine Island Glacier.
The blog details his journey to learn more about why the glacier's ice
shelf is experiencing accelerated thinning of its ice, causing an
impact on sea level.
- Petermann Glacier, Greenland
-- Seasonal changes in Greenland ice sheets during summertime are
apparent in this image of the Petermann Glacier, located in the far
northwestern part of the island.
- Northwest Passage Nearly Open
-- Explorers have sought a Northwest Passage for centuries, meeting
with disappointment and tragedy each time. Even now, navigating from
the Atlantic to the Pacific through Canada's Arctic Islands has been
difficult. The summer of 2007, however, saw sufficient sea ice retreat
to change the character of the fabled sea route.
- Volcanic Ash on Slopes of Karymsky
-- Of the volcanic products that linger on the land, most of us think
of hardened lava flows, but volcanic ash can also persist on the
landscape. One example of that persistence appeared on Siberia's
Kamchatka Peninsula in spring 2007.
- Iceberg A22A, South Atlantic Ocean
-- These Space Station astronaut photographs capture the remains of a
giant iceberg that broke off Antarctica in 2002. The iceberg was
photographed on May 30 about a third of the distance from South America
towards Cape Town, South Africa.
