The measurements were carried out by using a double monochromator-based spectroradiometer during a campaign in December meant to weight up the effect of the local albedo on the UV irradiance. We found that the albedo measured at noon was about 0. Spectral measurements carried out elsewhere as well as estimates retrieved from the Ozone Monitoring Instrument OMI were used for further comparisons. Academic Editor : Juan A.

This is the first in a series of case studies on adventurers, athletes and historical men and women who pushed their limits and challenged the status quo in order to the impossible and do things no one had ever done before. He led three expeditions to the Antarctic, including a disastrous expedition which saw his ship get trapped in ice before being crushed and sinking. Overcoming horrific obstacles and defeating all the odds, Shackleton led all his men to safety, and the expedition became known as one of the most most epic feats of endurance and leadership of all time. Ernest Shackleton was born in Ireland in As a child, he loved reading, and the books he read made him desperate for adventure.
Most dire projection of sea-level rise is a little less likely, reports say
Image courtesy of William Stout In , two researchers from Augustana College made a strange discovery in the mountains of Antarctica. While excavating a siltstone formation km from the South Pole, William Hammer and William Hickerson uncovered the skull and bones of a large carnivorous dinosaur. Found alongside the gnawed ends of the bones were the teeth of other smaller scavenging dinosaurs and fossilized tree trunks. What could explain the presence of these plants and animals in a location that today is so cold and lifeless?
