"Ye canna change the laws of physics!" Scotty warned Captain Kirk on "Star Trek." But engineers and physicists at the University of Maryland may rewrite one of them.The Third Law of Thermodynamics is on the minds of John Cumings, assistant professor of materials science and engineering at the University of Maryland's A. James Clark School of Engineering, and his research group as they examine the crystal lattice structure of ice and seek to define exactly what happens when...
Although new evidence suggests that a long-term thawing of Arctic sea ice is currently under way, scientists withdrew previous prediction that the ice would shrink below a 2007 record low this year.Previous reports highlighted a fear that the drastic melt witnessed in 2007 could lead to a total melt of ice on the North Pole. "Most likely there will not be a new record minimum ice year in the Arctic this September," said Ola M. Johannessen of the Nansen Environmental and Remote...
DENVER, July 24 /PRNewswire-FirstCall/ -- Apollo Gold Corporation ("Apollo" or the "Company") (TSX:APG, AMEX:AGT) today announced that it has closed the previously announced offering of units ("Units"). A total of 40,806,500 Units were subscribed for at a price of Cdn$0.50 per Unit (US$0.495 per Unit for purchasers residing in the United States), for total gross proceeds of $20,215,750 and US$185,625. Each Unit is comprised of one common share and one-half of one common share purchase...
Climate scientists from the Alfred Wegener Institute present their own prognosis for the first timeThe ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 "“ the year with the second lowest sea ice extent ever measured. Chances of an equally low value as in the extreme conditions of the year 2007 lie around eight per cent. Climate scientists from the Alfred Wegener Institute for Polar and Marine Research in the...
By JOHN C LORSON By JOHN C. LORSON Columnist "She'll be coming 'round the mountain when she comes. ..." Since the very first moment the sun sliced through the clouds of March, and children began to once again consider the outside world as a hospitable, even alluring environment, the Ice Cream Man has filled our neighborhood with the ubiquitous audible reminder that he will be "coming around the mountain" all too soon. I hardly exaggerate when I say that I have heard his dog- worrying,...
By Tom Beal, The Arizona Daily Star, Tucson Jun. 30--It's 9:30 a.m. at the University of Arizona's Central Refrigeration Building on East Helen Street. The day is rapidly warming toward triple digits. Time to melt some ice. Plenty is on hand on this Thursday morning. Overnight, the plant's chillers have been pumping 17-degree antifreeze through 156 storage tanks that now hold 23,000 tons of ice. At another site, at 640 N. Mountain Ave., 49 more tanks boost the ice total to about 30,000...
Many polar scientists believe that ice at the North Pole stands a good chance of completely disappearing over the course of the year. Some scientists say the ice at 90 degrees north may well have melted away by the summer.The massive melting of such a well-known arctic location would be a symbolic example of the great impact of global warming. "From the viewpoint of science, the North Pole is just another point on the globe, but symbolically it is hugely important. There is supposed...
Predicting climate change depends on many factors not properly included in current forecasting models, such as how the major polar ice caps will move in the event of melting around their edges. This in turn requires greater understanding of the processes at work when ice is under stress, influencing how it flows and moves. The immediate objective is to model the flow of ice sheets and glaciers more accurately, leading in turn to better future predictions of global ice cover for use in climate...
THERE is a new name in mineral water about to be launched in the UK and we're giving you the chance to try it FREE for a month. Isklar means "ice-clear" in Norwegian and is the name of the new glacial natural mineral water to reach our shores. It originates from a 6000-year-old glacier, set deep in the breathtaking and enchanting mystical wilderness of the Hardanger region of Norway, among soaring mountains, cascading waterfalls and crystal-clear fjords and protected by two vast...
An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible.The scientists, mainly from Denmark, UK, Germany and Canada, are currently in the middle of CryoSat Validation Experiment (CryoVEx) 2008, an extensive three-week experiment program in the far north of...

James Irwin was an American astronaut, an engineer, and was the eighth person to walk on the moon. He was born James Benson Irwin on March 17, 1930 in Pittsburgh, Pennsylvania. He lived a fairly normal childhood and graduated from East High School in Salt Lake City, Utah in 1947. He went on to attend the United States Naval Academy and received a Bachelor of Science degree in 1951. Following the Naval Academy, he attended the University of Michigan and earned a Master of Science in...
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...
