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 […]

Plate tectonics thanks to plumes?

“Knowing what a chicken looks like and what all the chickens before it looked like doesn’t help us to understand the egg,” says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and the early history of the Earth. The Earth’s lithosphere is divided into several plates that are in constant motion, and today’s geologists […]

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 […]

A Moon With Water

Astrobiologists searching the heavens for extraterrestrial life have a simple motto: “Follow the water, ”says The Washington Post. Water is an essential ingredient in all earthly biochemistry, so scientists believe it’s logical to look for life first on planets and moons with liquid water.New data from NASA’s Cassini spacecraft indicate that Enceladus, a tiny, ice-encrusted moon orbiting Saturn, may be […]
