A remarkable ESA campaign in one of the remotest regions on Earth has been fundamental in ensuring that the SMOS mission is delivering reliable data to improve our understanding of Earth´s water cycle. The two-year campaign set out to answer a simple but important question: do the microwave signals of a particular wavelength emitted from the surface the Antarctic ice shelf towards the SMOS satellite change over time? For a satellite mission that maps variations in soil...

The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet. A publication appearing in the journal “Science” on 1 December now furnishes indications that the two hemispheres attained...

Global Temperatures On The Rise
2011-11-30 07:00:38

The UN´s World Meteorological Organization (WMO) has issued a new report, the annual World Meteorological Organization Statement on the Status of the Global Climate. The report was released Nov. 29 in Durban, South Africa at an international climate conference. The report states that 2011 was the tenth warmest year on record and the surface temperatures were higher than any previous year with a La Nina event, which has a cooling effect. The report also notes that the incidence of...

The National Snow and Ice Data Center reports that Arctic sea ice continues to shrink each summer to nearly record low levels, with this year´s ice loss the second-lowest ever since records first began being taken in 1979. Despite only a few decades worth of records, a new study, published in the British journal Nature, found that “both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years,” reported the authors. The...

Arctic Sea Ice Could Melt Away By 2015
2011-11-09 06:19:43

A Cambridge University professor and one of Britain´s top ocean experts says that Arctic sea ice could melt away entirely by 2015, the Telegraph reported on Tuesday. Although the ice would reappear again every winter, its absence during the peak of summer would deprive polar bears of their summer hunting ground, which could put them at risk of extinction, said Professor Peter Wadhams of Cambridge University. The vast mass of sea ice between northern Russia, Canada and Greenland...

Image 1 - Researchers Report On Changes In Arctic Sea Ice
2011-10-06 11:09:06

In the central Arctic the proportion of old, thick sea ice has declined significantly. Instead, the ice cover now largely consists of thin, one-year-old floes. This is one of the results that scientists of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association brought back from the 26th Arctic expedition of the research vessel Polarstern. The ship arrived at its home port of Bremerhaven at about 7 o´clock this morning. Prior to that it had covered more...

Arctic Sea Ice Continues Decline, Hits 2nd-Lowest Level
2011-10-05 10:11:51

[ Watch the Video ] Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder showed that the summertime sea ice cover narrowly avoided a new record low. The Arctic ice cap grows each winter as the sun sets for several months and shrinks each summer as the sun rises higher in the northern sky. Each year the...

Model Provides Successful Seasonal Forecast For The Fate Of Arctic Sea Ice
2011-09-23 03:44:18

  Relatively accurate predictions for the extent of Arctic sea ice in a given summer can be made by assessing conditions the previous autumn, but forecasting conditions more than five years into the future depend on understanding the impact of climate trends on the ice pack, new research shows. Current conditions form an important starting point that governs how the ice responds to weather in the course of a few years, University of Washington-led research shows. But eventually...

Bowhead Whales Use Northwest Passage To Migrate
2011-09-22 12:44:41

   According to research published in the journal Biology Letters, bowhead whales are using the Northwest Passage to move across the top of the Americas. Scientists analyzed skeletons, DNA samples and harpoon heads and found these giants of the Arctic living on each side of the continent did meet and mingle. Mads Peter Heide-Jorgensen from the Greenland Institute of Natural Resources and colleagues satellite-tagged over 100 bowheads over the last decade. The researchers...

Arctic Ocean
2013-04-18 22:31:23

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...
