Sea Ice (Page 4)
Sea ice disappearing faster than predictedNew Zealand Herald | 13 Aug 2012
Sea ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from a satellite launched to study the thickness of Earth's polar caps.
Arctic sea ice 'melting faster'BBC | 13 Aug 2012
Arctic sea ice is vanishing much faster than generally expected, according to preliminary data from the Cryosat spacecraft.
Loss of Arctic sea ice '70% man-made'Guardian Unlimited | 25 Jul 2012
The radical decline in sea ice around the Arctic is at least 70% due to human-induced climate change, according to a new study, and may even be up to 95% down to humans – rather higher than scientists had previously thought.
Glacier break creates ice island 2 times the size of ManhattanEurekAlert | 18 Jul 2012
An ice island twice the size of Manhattan has broken off from Greenland's Petermann Glacier, according to researchers at the University of Delaware and the Canadian Ice Service. This is the second massive break in two years.
Atlantic heat constrains Arctic sea ice extentScienceDaily.com | 27 Jun 2012
The Arctic sea ice cover is a sensitive indicator of climate variability and change. Researchers have for the first time quantified how Atlantic heat influences the sea ice extent in the Barents Sea, where the retreat in Arctic winter sea ice is the most pronounced.
Record low sea ice cover for JuneGuardian Unlimited | 27 Jun 2012
Sea ice in the Arctic has melted faster this year than ever recorded before, according to the US government's National Snow and Ice Data Centre (NSIDC). Satellite observations show the extent of the floating ice that melts and refreezes every year was 318,000 square miles less last week than the same day period in 2007, the year of record low extent, and the lowest observed at this time of year since records began in 1979.
Emperor penguins threatened by Antarctic sea ice lossEurekAlert | 21 Jun 2012
A decline in the population of emperor penguins appears likely this century as climate change reduces Antarctic sea ice, according to a detailed projection published this week. The study concludes that the number of breeding pairs in a much-observed penguin colony may drop by about 80 percent by 2100.
Melting Sea Ice Threatens Emperor PenguinsWoods Hole Oceanographic Institution | 21 Jun 2012
At nearly four feet tall, the Emperor penguin is Antarcticas largest sea bird—and thanks to films like March of the Penguins and Happy Feet, its also one of the continents most iconic. If global temperatures continue to rise, however, the Emperor penguins in Terre Adélie, in East Antarctica may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution (WHOI).
CryoSat goes to seaScienceDaily.com | 29 May 2012
CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies. High-resolution mapping of the topography of the ocean floor is now being added to the ice mission's repertoire. The main objective of the polar-orbiting CryoSat is to measure the thickness of polar sea ice and monitor changes in the ice sheets that blanket Greenland and Antarctica.
Arctic sea-ice loss didn't happen by chanceScienceDaily.com | 03 May 2012
The ongoing rapid retreat of Arctic sea ice is often interpreted as the canary in the mine for anthropogenic climate change. In a new study, scientists have now systematically examined the validity of this claim. They find that neither natural fluctuations nor self-acceleration can explain the observed Arctic sea-ice retreat. Instead, the recent evolution of Arctic sea ice shows a strong, physically plausible correlation with the increasing greenhouse gas concentration.
Ice satellite is 'powerful tool'BBC | 24 Apr 2012
Europe's Cryosat spacecraft is now watching the ebb and flow of Arctic sea ice with high precision, report scientists.
NRL scientists optimize arctic sea ice data productsEurekAlert | 27 Mar 2012
(Naval Research Laboratory) Recent dramatic changes in the characteristics of the Arctic sea ice cover have sparked the demand for improved monitoring and forecasting. NRL and NASA are collecting data to aid in the validation and calibration for the development of predictive sea ice models.
Increase in Arctic shipping is risk to marine mammalsScienceDaily.com | 19 Mar 2012
A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region's marine mammals and the local communities that rely on them for food security and cultural identity, according to experts.
Thickest parts of Arctic ice cap melting fasterScienceDaily.com | 29 Feb 2012
A new study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean's floating ice cap.
Arctic sea ice decline may be driving snowy winters seen in recent yearsEurekAlert | 27 Feb 2012
A new study led by Georgia Tech provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's findings could be used to improve seasonal forecasting of snow and temperature anomalies across northern continents.
Melting Arctic link to UK snowsBBC | 27 Feb 2012
The progressive shrinking of Arctic sea ice is bringing colder, snowier winters to the UK and other parts of the Northern Hemisphere, scientists show.
