Arctic Ice And The Voyage Of The Titanic

Brett Smith for redOrbit.com - Your Universe Online One hundred and two years ago this week, the Titanic set off on its fateful maiden voyage from the United Kingdom. Coinciding with that anniversary is a new report from British researchers who...

Major Increase In West Antarctic Glacial Loss
2014-03-28 17:26:44

American Geophysical Union Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union. Pine Island Glacier, the most active of the studied...

Greenland Ice Sheet Receding And Is Now Considered Unstable
2014-03-17 10:26:10

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal Nature Climate Change, the last stable section of the Greenland ice sheet is receding and now considered unstable – a development that could portend even more ice loss in the future and significant sea level rise. The report focused on a key ice stream in the Greenland ice sheet. Ice streams drain an ice basin from the interior of the sheet, in the same way that regular streams drain water...

Greenland Jakobshavn Glacier

Lee Rannals for redOrbit.com - Your Universe Online New data obtained by NASA's Operation IceBridge program is shedding new light on how ice sheets in Greenland are changing. Scientists used satellite observations and ice thickness measurements made by Operation IceBridge to determine the rate at which ice flows through Greenland’s glaciers into the ocean. The findings have shown how glacier flow is affecting the Greenland Ice Sheet and that this process is being dominated by a small...

redOrbit Staff & Wire Reports - Your Universe Online Previous instances of rapid thinning of Pine Island Glacier suggests that current ice loss in the Antarctic could continue for several more decades, a team of geologists from the US, UK and Germany report in this week’s edition of the journal Science. Pine Island Glacier, which is part of the West Antarctic Ice Sheet, is rapidly accelerating, thinning and retreating, and the researchers report that it has thinned rapidly in the...

Greenland Ice Sheet
2014-02-07 04:35:58

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Nature say that ocean warming could be causing a four-fold increase in ice loss on the Greenland Ice Sheet. The Greenland Ice Sheet is about a 2-mile thick layer of ice that covers the country. Glaciers that drain the ice sheet plunge into coastal fjords that are about 2,000 feet deep, helping to expose the ice sheet edges that contact the ocean. Oceanographers from Woods Hole Oceanographic...

World's Fastest Moving Glacier Found In Greenland
2014-02-03 12:45:37

[ Watch the Video: Fastest Glacier In The World ] Lee Rannals for redOrbit.com - Your Universe Online Researchers from the University of Washington and the German Space Agency (DLR) say that a Greenland glacier is slipping off into the ocean at a speed never before seen. The scientists measured the speeds of Jakobshavn Isbræ (Jakobshavn Glacier) in Greenland and found that this glacier is the fastest moving ice sheet ever recorded. “We are now seeing summer speeds more than 4...

Pine Island Glacier Retreating
2014-01-14 14:44:51

Lee Rannals for redOrbit.com - Your Universe Online Antarctica’s Pine Island Glacier (PIG) is now in an irreversible retreat, according to a study published in the journal Nature Climate Change. PIG is one of the biggest single contributors to global sea-level rise, and the latest study says that it could add as much as 0.39-inches to ocean levels in 20 years. “Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating rate, so that at present it is...

Long Unchanged Alpine Glacier Is Now Melting At Unprecedented Rate
2013-12-12 06:35:56

April Flowers for redOrbit.com - Your Universe Online An international team of glaciologists, led by Ohio State University, has discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate. The discovery, described at the annual autumn meeting of the American Geophysical Union this past week, was made less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman. A single, dried-out leaf from a larch tree...

Arctic Fossil Record Traces Greenland Ice Sheet's Past
2013-11-23 05:24:05

April Flowers for redOrbit.com - Your Universe Online There have been many studies telling us how small the Greenland ice sheet is today. A new study, published in the journal Geology, reveals that the ice sheet was actually smaller between 3,000 and 5,000 years ago. Surprisingly, the sheet was as small during this period as it has ever been in recent history. The international research team used a new technique they developed for interpreting the Arctic fossil record. “What’s...

Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer. Studies of the Greenland ice sheet, including during a record warm summer, are helping scientists better understand how summer conditions affect its flow. This is important for predicting the future...

White frost is a type of solid ice that forms directly from water vapor found in the air. White frost forms when the humidity is above 90% and the temperature is below 18 degrees Fahrenheit. White frost grows against the wind, since the facing winds have higher humidity than leeward air. The wind must be light or the delicate icy structures become broken. The structures have big, interlocking, needle-like crystals. This phenomenon occurs very rarely. White frost is considered an intermediate...

Soft rime is a type of milky white ice that forms when water droplets in light freezing fog freeze to the outer surfaces of objects. This formation usually occurs with light winds or in calm conditions. The rime forms to the windward (side facing the wind) side of solid objects. Soft rime is similar in appearance to hoar frost, but is formed differently. Soft rime is formed when vapor first condenses to liquid droplets and then attaches to the surface. Hoar frost is formed when water vapor is...

Hard rime is a type of white ice that forms when water droplets found in fog freeze to the outer surfaces of objects. Hard rime is most often found on trees atop mountains and high ridges in winter, when low clouds cause freezing fog. This fog freezes along the windward (sides facing the wind) side of trees, buildings, and any other solid objects. The air temperature needed for hard rime to form is less than 29 degrees Fahrenheit and typically higher than 17 degrees Fahrenheit. High wind is...

Clear Ice refers to a solid precipitation that forms when air temperature is between 32 degrees and 27 degrees Fahrenheit and there is a presence of super-cooled, large drops of water (from freezing fog). A rapid build up and slow dispersing of latent heat of fusion favors conditions for the formation of the transparent ice. A similar phenomenon occurs when freezing rain or drizzle hit's a surface and freezes causing what is known as glaze. When clear ice forms on the ground, it is...

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
