Sea Levels Rising Fast
2012-11-02 08:28:50

April Flowers for redOrbit.com - Your Universe Online Global warming is causing sea levels to rise faster than previously expected and geologist Bill Hay from the University of Colorado Boulder has a theory to explain why. The most recent IPCC report released in 2007 projected a global sea level rise between 0.2 and 0.5 meters by 2100, but current sea level measurements meet or exceed the high end of that range. This suggests a rise of one meter or more by the end of the century....

Ice Caps Grow and Shrink
2012-10-24 20:26:45

Brett Smith for redOrbit.com — Your Universe Online Over the past few years, researchers have consistently shown an overall decrease in the size of the Arctic ice cap–particularly during the summer months when the most melting occurs. However, a new study from NASA scientists has shown that this melt off around the Arctic is accompanied by the record expansion of sea ice around Antarctica, when the Southern Hemisphere is experiencing its colder temperatures of the year....

Understanding Antarctic Ice Loss
2012-10-22 19:44:40

Alan McStravick for redOrbit.com — Your Universe Online Amazing GRACE. Scientists and researchers have some interesting news out of Antarctica. The rate of global sea level change has been fairly well-established. The understanding for exactly why this is occurring got a new wrinkle this past week. Utilizing the Gravity Recovery and Climate Experiment (GRACE) satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes...

Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier. The first science flight of the campaign began Friday at 8 a.m. EDT when NASA's DC-8 research aircraft left Punta Arenas, Chile, for an 11-hour flight that will take it...

Polarstern Has News About Arctic Sea Ice
2012-10-11 18:43:41

Alan McStravick for redOrbit.com — Your Universe Online The Polarstern expedition has disconcerting news about our rapidly receding sea ice. The Polarstern, an ice-breaking research vessel, returned to the port of Bremerhaven two days ago. The Polarstern, operating on behalf of the Alfred Wegener Institute, was conducting research into the retreat of sea ice and the impact it will have on the Arctic Ocean and its ecosystems over the last two months. In all, 54 researchers and...

ESA Satellites Taking A Deeper Look Into Sea Ice
2012-10-05 08:28:31

This year, satellites saw the extent of Arctic sea ice hit a record low since measurements began in the 1970s. ESA´s SMOS and CryoSat satellites are now taking a deeper look by measuring the volume of the sea-ice cover. Measurements from ESA´s Soil Moisture and Ocean Salinity (SMOS) mission show that ice has thinned significantly in the seasonal ice zones, with extensive areas less than half a metre thick. Sea ice has a large influence on the heat exchange between the ocean...

Arctic Ice Reaches Least Extent Since 2007 Summer Season
2012-09-20 09:23:03

Lawrence LeBlond for redOrbit.com - Your Universe Online The Arctic sea ice has stopped receding this year, but not before reaching its smallest extent, breaking the previous record set in the summer of 2007, by 18 percent. The new low sets the summertime ice area extent to about 2.1 million square miles, according to estimates from the US National Snow and Ice Data Center (NSIDC) in Colorado. This year´s unprecedented ice melt in the Arctic is the clearest sign yet of global...

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

Lee Rannals for redOrbit.com — Your Universe Online A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay. The team tested high-resolution model simulations against reconstructions of the Antarctic ice sheet from 20,000 years ago. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), they said they used a new model during their study, capable...

Arctic Sea Ice Loss Could Have Major Impacts
2012-09-10 06:24:56

redOrbit Staff & Wire Reports - Your Universe Online As the end of the Arctic melt season ends with the region having already set new records for the smallest amount of sea ice extent and volume, experts this past weekend began to gauge exactly what the implications will be, both locally and throughout the rest of the world. According to BBC News Science Editor David Shukman, scientists at the Norwegian Polar Institute (NPI) have reported that the sea ice in the area was becoming...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
