Giant Underwater Canyon Zhemchug
Can Only Be Seen Entirely From Space

6 April, 2012

MessageToEagle.com - We continue to explore amazing places on our beautiful planet.

This time we take a journey deep beneath the oceans. Hidden beneath all that water are some of the biggest natural formations on earth.

Deep underwater we find the longest mountain ranges, the tallest volcanoes and the deepest canyons.

We might think that Grand Canyon is big, but it is nothing compared to Zhemchug that is so huge it can only be seen entirely from space!

Zhemchug Canyon is a giant underwater canyon located in the middle of the Bering Sea.

It is deeper than the Grand Canyon (1.83 km deep) at 2.6km deep. Zhemchug Canyon is the largest submarine canyon in the world, based on drainage area (11,350 km2) and volume (5800 km3).

Zhemchug Canyon is the largest canyon on our planet.

Named after a Soviet research ship and a word meaning "pearl," Zhemchug Canyon cuts into the ocean floor at the western edge of the Continental Shelf, "one of the flattest and smoothest places on the planet," Dan O'Neill wrote in his book, The Last Giant of Beringia.

"Its slope, at no more than three or four inches per mile, is almost unmeasurable!"

More about this programme: http://www.bbc.co.uk/programmes/b012t6ly Zhemchug Canyon is in the Bering Sea and is the largest canyon in the ocean it has a vertical drop over 2500 metres.

This is what Zhemchug Canyon looks from space.

It is normally hidden by the pacific Ocean, but the Zhemchug is so wide it is impossible to see from one side to the other, unless you are above the curvature of the Earth.

The endangered short-tailed albatross congregates to feed over the surface waters of the canyon.

Marine mammals such as Northern Fur Seal feed in the canyon as do many species of whales.

Habitat-forming invertebrates such as Bubblegum Coral, bamboo coral, soft corals, Hexactinellid sponges, and other sponges have been identified during trawl surveys in the canyon.

It is where the Opilio (Snow Crab) crab and Baridi crab can be found Opilio crab are shown in the Opilio season on Deadliest Catch. Only in the last five years have scientists have begun to plumb the depths of Zhemchug, and we still have virtually no information on what marvels it may conceal.

Extreme Life In Tough Environment Of Hot Earth Without Oxygen
Once upon a time, Earth was still a hot, violent place at this time, with volcanic activity dominating the early Earth. The sky was cloudy and grey, keeping the heat in despite the sun being weaker than today. The water temperature of the oceans was much higher at 40-50 degrees (the temperature of a hot bath) and circulating currents were very strong.

Archaeologists believe there are ruins of an ancient lost civilization beneath the waters of the Indian Ocean. Evidence suggest humans lived in the area in and around the Persian Gulf Oasis for over 100,000 years before the region was swallowed up by the Indian Ocean about 8,000 years ago.

Extreme Weather: Rare Supercell Thunderstorm Produces Monster Hailstone
Just recently scientists announced they found new evidence linking Earth's extreme weather to human-caused global warming. Now, the National Weather Service office in Honoulu in coordination with the State Climate Extremes Committee has confirmed that a rare supercell thunderstorm has produced new state hail size record.

Solar Tornadoes As Wide As Five Earths Discovered
Solar tornadoes several times as wide as the Earth can be generated in the solar atmosphere, say researchers in the UK. "This is perhaps the first time that such a huge solar tornado is filmed by an imager. Previously much smaller solar tornadoes were found my SOHO satellite. But they were not filmed," says Dr. Xing Li, of Aberystwyth University.

Living Earth Simulator - Supercomputer Predicting The Future
In Douglas Adams book the Hitchhikers Guide to the Galaxy we encounter a machine called Deep Thought. It is the most powerful computer ever built. Deep Thought is capable of answering questions concerning life, the Universe, and simply everything. Now scientists are planning to create a similar machine. It is called the Living Earth Simulator (LES).

New Evidence Links Earth's Extreme Weather To Human-Caused Global Warming
The past decade has been one of unprecedented weather extremes. Scientists of the Potsdam Institute for Climate Impact Research (PIK) in Germany argue that the high incidence of extremes is not merely accidental. From the many single events a pattern emerges. At least for extreme rainfall and heat waves the link with human-caused global warming is clear...

Proof Of How The Universe Is Changing

Though the universe is filled with billions upon billions of stars, the discovery of a single variable star in 1923 altered the course of modern astronomy. And, at least one famous astronomer of the time lamented that the discovery had shattered his world view.

Over time, astronomers have watched and waited for the expanding debris from this tremendous stellar explosion to crash into previously expelled material...
