What’s It Like to Work and Play in Antarctica’s Mac Town?

Nature films and science documentaries usually portray Antarctica to be nothing but the most cold, isolated, almost anti-social continent on earth — at least if you’re not a penguin — but life at McMurdo Station disproves that. The 2011-2012 Antarctic southern summer season is now alive and kicking (after numerous delays), and “Mac Town” (as the residents of McMurdo call […]

Giant boost for south polar waters

Giant boost for south polar waters

Massive icebergs more than 18km long give Giant boost for south polar waters by feeding vital nutrients into the Southern Ocean and helping to increase its carbon storage capacity. LONDON, January, 2016 – British scientists have identified the monsters that fertilize the Southern Ocean and help remove carbon dioxide from the atmosphere. Giant icebergs drifting northwards could be responsible for storing up […]

Strange Plumes On Mars

  Mysterious plumes of gas rising more than 150 miles above the surface of Mars have left scientists confounded. On two occasions in the spring of 2012, amateur astronomers spotted a cloud developing on the surface of the Red Planet. The plumes, which spanned about 600 miles in diameter and changed shape constantly, appeared within a few hours and remained […]

How Sea Ice Forms

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 degrees Celsius (28.8 degrees Fahrenheit). Most Antarctic sea ice occurs annually, meaning it forms in the winter and melts during the summer. Sea ice regulates exchanges of heat, moisture and salinity in the polar oceans. It insulates the relatively warm […]

Tracing The Moon’s Origins

Some new thinking may have brought astronomers a step closer to solving the mystery of how our moon formed. Researchers have long believed that the moon was cleaved from a Mars-sized planet that collided with Earth some 4.5 billion years ago. Yet recent tests of lunar rock samples suggest that the moon’s chemical makeup is too similar to Earth’s to […]

International team of scientists reports on Antarctic lead pollution

Researchers from Australia, Denmark, Germany, Norway, United Kingdom, and the United States conducted lead concentration measurements of sixteen ice core samples, and found that industrial air pollution has persisted Antarctica since its arrival there in 1889 and remains significant in the current century. Their study was published in Scientific Reports on July 28, and covered in Nevada‘s Review journal. Lead […]

The Hungry Planet

More than 850 million people around the world—one in nearly seven—don’t have enough to eat. Although current global food production is sufficient to feed everyone, the number eating less than the minimum the human body needs—an average 2,100 calories a day for adults—now grows by more than ten million a year, mostly in the poorest nations. Countries with unstable food […]
