Image of the Day: A Crack Across the Pine Island Glacier

Repost This

A massive crack extending for 19 miles across the Pine Island Glacier in Antarctica was discovered last October by NASA scientists working in the area. The crack is 260 feet wide, 195 feet deep and will eventually extend all the way across the glacier, calving a giant iceberg that will cover about 350 square miles. This image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft on Nov. 13, 2011.

THESE ARE NOT GOOD SIGHNS FOR THE FUTURE HEALTH OF OUR WORLD.IF THIS GLOBAL WARMING CONTINUES AT IT’S PRESENT PACE,WE WILL LOOSE ALL OUR GLACIERS.AND ALL GLACIER ANIMALS WIL BE DOOMED UNLESS SOMETHING RAPIDLY IS DONE.IT’S USELESS TO KNOW ABOUT IT AND DO NOTHING.THE COUNTRIES ARE LOCKED IN THEIR ECONOMIES WITHOUT REALISING THAT IT WOULD BE DETRIMENTAL TO ALL ADIO THAN ECONOMIES.

I wish the picture would have shown where the crack ends.

It is possible to watch the coast of Antarctica day and night, using radar images compiled from the ASAR imaging radar of ESA’s Envisat satellite. These are compiled by Polarview, and hosted by the British Antarctic Survey on the website here:  http://www.polarview.aq/mapview.php
No need to wait for a sunny cloud free day to watch the action unfold…  Check it out.
