| Under the Radar: Unearthing Antarctica's Surface below 10,000 Feet of Ice The ice covering Antarctica got its start on the top of a high peak in the Gamburtsev mountains about 43 million years ago, according to a new study published today in Nature. Using simple radar to peer through the ice, researchers have gained new insights about the hidden mountains--and the formation of the ice that entombs them.

Voyage to the Pacific Ocean's garbage patch: The middle of the Pacific is teaming with life--and trash Editor's Note: Scuba instructor and underwater videographer Drew Wheeler is traveling on board the Algalita Marine Research Foundation's 50-foot Ocean Research Vessel, Alguita, on a two-month voyage to sample and study portions of a 10-million-square-mile oval known as the North Subtropical Gyre (aka "Pacific garbage patch"). Wheeler and the rest of the Alguita crew left Long Beach, Calif., on June 10 with a plan to cross the International Date Line and investigate regions of reported high plastic concentrations, northwest of the Hawaiian Islands.

Got Goat's Milk? The Quest to Save Dairy from Climate Change In July 2006, a monthlong triple-digit heat wave scorched California, killing more than 25,000 cattle and reducing dairy production in the region. Land O'Lakes Creameries, which normally produces six million liters of milk daily, was short 1.5 million liters per day.

Plastic, plastic everywhere, nor any bite to eat: Pacific albatrosses feast on garbage patch offerings As harbingers of ill fate in maritime lore, albatross have, themselves, come to be an indicator for modern-day oceanic pollution.

"Mining permits are being issued despite the preponderance of scientific evidence that impacts are pervasive and irreversible and that mitigation cannot compensate for losses," the scientists wrote in the January 8 issue of Science . "Regulators should no longer ignore rigorous science." [More] rss.sciam.com |
