Expeditions to the Polar Regions

netbros — Mon, 09 Nov 2009 10:01:49 -0800

The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through photo essays and other multimedia, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at WHOI.

Saturn Equinox

Cassini Reveals New Ring Quirks, Shadows During Saturn Equinox. "It's like putting on 3-D glasses and seeing the third dimension for the first time," said Bob Pappalardo, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "This is among the most important events Cassini has shown us." Latest press images.

Blood Falls - The iron rich red liquid gushing from a buried Antarctica lake shows how life may have existed on a snowball Earth, or on Europa.

'There is no such thing as polywater because if there were, there would also be an animal which didn't need to eat food. It would just drink water and excrete polywater' - Richard Feynman

If you were doing research in the 60s, You might've heard of Polywater, A form of water that exhibited wide variety of interesting characteristics and existed under identical conditions to that of normal water. Eventually debunked, none the less is a fascinating story. Naturally one draws parallels to Vonnegut's ice nine, but did you know there actually is an ice nine? In fact, there's twelve to sixteen types of ice, depending on your opinion. More recently, computer simulations have indicated water may structure itself into icosahedra, which, incredibly, is the platonic solid (described over 2000 years ago!) representing the element water! And if you don't know what an icosahedron is, I bet you've used one before. One of the most ubiquitous, and arguably most important, substances in our lives, our understanding of water is far from complete.

Landsat Image Mosaic Of Antarctica UK and US researchers peice together the most detailed map of Antarctica yet, searching through years of data to find cloud free images.

September 2007 polar sea ice anomaly

Video (8MB, MPEG) of arctic sea ice extent, recorded from January to September 2007. [other formats] This summer a dramatic decrease compared to previous years in the extent of the north pole ice cap was observed. Scientists are freaked out [bugmenot]. This summer, the Northwest Passage was open for a few weeks, allowing three ships to traverse it. This data was taken by the Advanced Microwave Scanning Radiometer instrument aboard NASA's Aqua satellite. Comparison with past years. More information here.

Welcome To The Top of Europe

The Sphinx Observatory atop the Jungfraujoch in the Swiss alps is one of the most amazing man-made objects I've ever seen. A UNESCO world-heritage site, it holds the distinction of being the highest (in altitude) structure in all of Europe. Approachable by a train that runs inside the mountain (via a tunnel dug between 1896 & 1926 at the cost of a small fortune, not to mention many lives), the Observatory rests atop a glacier which has been hollowed out to feature a year round gallery of never-melting ice scultptures (glacial ice is spectacularly pretty), and an elevator up to the research station.

Great balls of ice falling from the sky!

Great balls of ice falling from the sky! Not a B-movie but a reality. Scientists are baffled by the 25-400lb ice balls falling from clear blue skies.

another canary tips over
as the administration (more specifically the white house council on environmental quality and its head james l. connaughton) continue to ignore and bury the warnings of the effects global warming from their own scientists.

Next Thursday, NASA will announce the discovery of huge water ice oceans on Mars. Lying less than a metre beneath the surface south of 60° latitude, the water ice reservoirs if melted would form an ocean 500m deep covering the entire planet. NASA insiders believe these findings could result in a manned landing within 20 years.

Scientist discovers way to change mechanical properties of ice by changing its electrical charge. Potential applications: instantly de-ice aircraft wings or car windshields or slow-down skis and snowboards.
