The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research. Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team...

A carefully executed operation to validate data from CryoSat has shown what can be accomplished when ESA, NASA and others join forces to further our understanding of how the fragile polar environment is responding to climate change. In support of ESA's CryoSat ice mission, which was launched a year ago to monitor changes in ice thickness, a grueling validation campaign is being carried out in one of the most inhospitable environments on Earth. The one-month Arctic expedition is a major...

To guarantee ESA's CryoSat mission is delivering the best data possible, scientists have set out on a major expedition to the Arctic "“ part of a collaborative effort between ESA and NASA to gather ice measurements as the satellite orbits above. CryoSat was launched a year ago today to monitor the changes in the thickness of marine ice in the polar oceans and in the vast ice sheets that blanket Greenland and Antarctica. Orbiting closer to the poles than any other satellite and carrying...

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center. The CU-Boulder research team believes the lowest annual maximum ice extent of 5,650,000 square miles occurred on March 7. The maximum ice extent was 463,000 square miles below the 1979-2000 average, an area slightly larger than the states of Texas and...

WASHINGTON, March 15, 2011 /PRNewswire-USNewswire/ -- Researchers and flight crew arrived in Thule, Greenland, on Monday, March 14, for the start of NASA's 2011 Operation IceBridge, an airborne mission to study changes in Arctic polar ice. This year's plans include surveys of Canadian ice caps and expanded international collaboration.

Ice sheets have been losing mass at an accelerated rate over the past two decades, and these changes could soon become the dominant contributor to rising global sea levels, a NASA-funded study has discovered. The results of the nearly 20-year satellite research project--the longest study ever to track changes in polar ice sheet mass--showed that ice sheets in Greenland and the Antarctic lost an average of 475 gigatons of combined mass annually. Each gigaton is roughly equal to 2.2 trillion...

Ongoing climate-driven changes to the Arctic sea-ice could have a significant impact on the blooming of tiny planktonic plants (phytoplankton) with important implications for the Arctic ecosystem, according to new research conducted by scientists at the UK's National Oceanography Centre (NOC)."Ice-edge phytoplankton blooms in the Arctic Ocean provide food for planktonic animals called zooplankton, which are in turn exploited by animals higher up the food chain such as fish," explained Dr...

Temperatures of North Atlantic Ocean currents flowing north into the Arctic Ocean are at their highest levels in nearly 2,000 years, and could ultimately lead to summers that are ice-free in the North Pole region, researchers claim in a new study. The waters of the Fram Strait, which is located at the northern end of the Gulf Stream near Greenland, have gotten approximately 3.5 degrees Fahrenheit warmer over the past century, study leader Robert Spielhagen of the Academy of Sciences,...

Changes within the seawater beneath the floating sea ice may be accelerating change in the Arctic and beyond London (PRWeb UK) January 26, 2011 A "Ëœthin blue line' of fresh water immediately beneath the Arctic sea ice may hold the key to understanding changes in ocean current s that influence the prevailing climate of Europe and the East Coast of North America. The Catlin Arctic Survey announced today that its team of polar explorers and scientists will be heading to the Arctic...

Scientists and explorers will shortly set off on an expedition aiming to discover how Arctic sea ice melts. This year's Catlin Arctic Survey is focused on the thin layer of water immediately under the floating ice. Arctic ice is melting faster in the summer than many computer models have predicted. Survey data could improve forecasts of the region's future, and show how likely it is that the flow of warm water in the North Atlantic will switch off. This would bring colder weather to the...

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
