Midnight Sun | Iceland (por SCIENTIFANTASTIC)

Midnight Sun: A natural phenomenon occurring in the summer months north of the Arctic Circle and south of the Antarctic Circle where the sun never fully sets and remains visible 24 hours a day. This short time lapse film was shot during the Icelandic Midnight Sun in June of 2011.

Russia’s northernmost territory, Franz Josef Land, is an archipelago of 191 islands in the northeastern Barents Sea. On August 17, 2011, clear skies allowed the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite this unobstructed view. Clouds fringe this natural-color scene, like curtains held back from a window. Around the islands, sea ice forms serpentine shapes of light gray and dull white. The glaciers that cap many of the islands are bright white. In ice-free areas, land cover is pale brown, typical of tundra. (via NASA Earth Observatory)

jtotheizzoe: Arctic sea ice drops to record low. Increased melting of sea ice is an “unerring indicator” of climate change, according to scientists. Although satellite data observing Arctic sea ice levels has only been available since 1972, some models say that this year’s record could be the lowest in 8,000 years. (via Nature News)

Arctic sea ice drops to record low.

Increased melting of sea ice is an “unerring indicator” of climate change, according to scientists. Although satellite data observing Arctic sea ice levels has only been available since 1972, some models say that this year’s record could be the lowest in 8,000 years.

Omulyakhskaya and Khromskaya Bays lie along the northern Siberian coast, southeast of the Lyakhov Islands. The northerly location almost guarantees ice in the adjacent East Siberian Sea, and permafrost blankets the land around the bays. The Thematic Mapper on the Landsat 5 satellite captured this natural-color image on June 15, 2009, when ice lingered on the sea surface and on some inland water bodies. The land around the bays is dotted with thermokarst lakes, which result from water released by thawing permafrost. (…) Because thawing permafrost and thermokarst lakes release carbon and methane—both greenhouse gases—scientists monitor these landscapes closely because of their implications for future climate.

The sea ice atop the Arctic Ocean can—as shown in this photograph from July 12, 2011—look more like swiss cheese or a bright coastal wetland. As ice melts, the liquid water collects in depressions on the surface and deepens them, forming melt ponds. These fresh water ponds are separated from the salty sea below and around it, until breaks in the ice merge the two. (via NASA Earth Observatory)

Mosaic of the Arctic (by NASA Goddard Photo and Video) On June 30, 2011 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite made multiple passes over the Arctic, capturing a true-color image of the summer lands and sea-ice near the North Pole on each pass. Individual images were then pieced together to create a large mosaic of the area, which gives a broader, circumpolar, view that would not be possible with individual images. Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team.

Earth from Space: Summer ice retreat (by europeanspaceagency) In this image, acquired on 23 June 2011, Envisat captures part of Greenland’s ice sheet and east coast as the winter sea ice recedes. Covering roughly 80% of the surface of Greenland, this ice sheet is the second largest body of ice in the world, after that of Antarctica. Credits: ESA.

Coast Guard marine science technician Dan Purse deploys the optical package off the fantail with Brian Schieber and Rick Reynolds, both of the Scripps Institution of Oceanography. The package measures light absorption and scattering by diverse contents in the water column such as water molecules, algae, and bacteria cells. Its frame carries a few pieces of optical equipment from different research groups. Photo by Haley Smith Kingsland. (via NASA’s Arctic Voyage)

CryoSat’s exceptionally detailed data have been used to generate this map of sea-ice thickness in the Arctic. Data from January and February this year have been used to show the thickness of the ice as it approaches its annual maximum. Thanks to CryoSat’s orbit, ice thickness close to the North Pole can be seen for the first time. Credits: CPOM/UCL/ESA. (via ESA)

The Arctic Light (by TSO Photography)

This was filmed between 29th April and 10th May 2011 in the Arctic, onthe archipelago Lofoten in Norway.

A new (and awesome!) time-lapse, this time from the Arctic.

The Shrinking Arctic Ice Cap (by GFDLCCVP)

Satellite observations show that Arctic sea ice extent has declined over the past three decades. Global climate model experiments, such as those conducted at NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), project this downward trend to continue and perhaps accelerate during the 21st century.
