Ice Loss Not Due To 2012 Arctic Cyclone
2013-01-31 20:18:02

Lee Rannals for redOrbit.com — Your Universe Online Researchers are disputing the theory that the culprit behind the historic sea ice minimum was "The Great Arctic Cyclone of August 2012." Writing in the journal Geophysical Research Letters, University of Washington researchers found that the freak summer storm was actually not solely responsible for 2012's record low for Arctic sea ice, but that other factors were in play. Jinlun Zhang, lead author of the paper, and...

Arctic Melt Ponds Are Forcing Rapid Sea Ice Loss
2013-01-18 15:16:11

Brett Smith for redOrbit.com - Your Universe Online Melt ponds, a favorite phenomenon among arctic photographers, are turquoise or dark blue pools of water that appear on ice floes during the Arctic summer. According to a new report in Geophysical Research Letters, scientists from the Alfred Wegener Institute (AWI) have been observing more and more melt ponds atop one-year ice floes, instead of meter-thick, multi-year ice that used to dominate, even during the warmest months in the...

New Twist To Sea Ice Forecasting Brought By NASA's Operation IceBridge Data
2012-12-20 12:57:40

NASA Shrinking Arctic sea ice grabbed the world's attention again earlier this year with a new record low minimum. Growing economic activity in the Arctic, such as fishing, mineral exploration and shipping, is emphasizing the need for accurate predictions of how much of the Arctic will be covered by sea ice. Every June, an international research group known as the Study of Environmental Arctic Change (SEARCH) publishes a summary of the expected September Arctic sea ice minimum known as the...

Climate Impacts Of Polar Low Arctic Hurricanes
2012-12-17 05:32:40

redOrbit Staff & Wire Reports - Your Universe Online The intense, small scale storms known as polar lows could have a tremendous impact on oceanic water circulation and climate predictions, a team of researchers from the US and UK have discovered. According to scientists from the University of East Anglia (UEA) and the University of Massachusetts at Amherst, the storms, which are also known as Arctic hurricanes, contain areas of extremely low barometric pressure and can produce...

Warm Seas Melting Antarctic Ice Sheet Faster Than Expected
2012-12-07 13:15:29

April Flowers for redOrbit.com - Your Universe Online The West Antarctica ice sheet is melting faster than expected. An international group of oceanographers led by the University of Gothenburg has published new observations in the journal Nature Geoscience that may improve our ability to predict future changes in ice sheet mass. The water levels of the oceans would be affected globally by a reduction of the ice sheets in Antarctica and Greenland, making it problematic that...

Ice Sheet Loss At Both Poles Is Clearly Increasing
2012-11-30 08:10:18

April Flowers for redOrbit.com - Your Universe Online In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date. Published in the journal Science, the landmark study shows that the melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimeters to global sea levels since 1992, amounting to one fifth of all sea level rise over the survey...

Ocean Currents Helps Predict Arctic Sea Ice
2012-11-21 15:07:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT have developed a new method for optimally combining models and observations of the Arctic Ocean to accurately simulate the seasonal extent of the ice change and the ocean circulation beneath. The Arctic Ocean freezes each winter to form sheets of sea ice that spread over millions of square miles. This ice then acts as a massive sun visor for the Earth and helps to reflect solar radiation and shield the planet from...

NASA Studies Antarctic Sea Ice
2012-11-14 19:43:13

Alan McStravick for redOrbit.com — Your Universe Online A new study by NASA and the British Antarctic Survey tries to explain the increase of ice cover in the Antarctic that is seemingly contrary to the effects of climate change that have been witnessed over the previous two decades. In their report, they purport they have the first direct evidence that this increase in sea ice cover is due to changing winds that have had an impact on the changes to Antarctic sea ice drift. The...

Winds Responsible For Antarctic Sea Ice Growth
2012-11-12 05:17:56

redOrbit Staff & Wire Reports - Your Universe Online While global warming has caused extensive melting of sea ice in the Arctic region in recent years, the opposite phenomenon has been occurring in Antarctica, and now experts believe they've discovered the reason why. In a report released Sunday, a team of scientists revealed that shifting wind patterns surrounding the southernmost continent have resulted in slight increase in regional sea ice. That conclusion comes following an...

What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University of...

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...
