MessageToEagle.com - Remote sensing from satellites is the most efficient way to get global information
about these vast, hard-to measure expanses like for example - our oceans.
The ocean is a major player in the Earth system. It is in constant motion. Winds drive currents on the ocean
surface and these currents in turn mix down into the ocean depths.
Data from buoys, drifters, and satellites such as ocean color, sea height, temperature, and
winds, provide us with observations about the speed and direction of currents and about heat stored in the ocean,
which help to predict global climate variations.
Working on a joint project, scientists of MIT and NASA's Jet Propulsion Laboratory, have produced a stunning new
animated video called Estimating the Circulation and Climate of the Ocean.
It displays the flow of the world's ocean currents swirling in captivating splendor.
The video, titled "Perpetual Ocean," takes an astronaut's view, as if the viewer is in a waltz-like dance orbiting around the Earth.
This visualization shows ocean surface currents around the world during the period from June 2005
through Decmeber 2007. The visualization does not include a narration or annotations; the goal was to use
ocean flow data to create a simple, visceral experience.

This visualization was produced using NASA/JPL's computational model called Estimating the Circulation and
Climate of the Ocean, Phase II or ECCO2.. ECCO2 is high resolution model of the global ocean and sea-ice.
ECCO2 attempts to model the oceans and sea ice to increasingly accurate resolutions that begin to resolve
ocean eddies and other narrow-current systems which transport heat and carbon in the oceans.
The video shows just how complex and vital the oceans are, and the intricacy by which heat and carbon is
transferred and transported. It's also fascinating to follow the tiny details of the currents regionally.
Try imagining yourself as a tiny paper boat and see where they might take you. The exercise may reveal an
amazing amount about how connected faraway places really are via the world's ocean currents.
It's a global world indeed.
The ECCO2 model simulates ocean flows at all depths, but only surface flows are used in this visualization.
The dark patterns under the ocean represent the undersea bathymetry. Topographic land exaggeration is 20x
and bathymetric exaggeration is 40x.
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.
Dangerous Fast and Furious - Birth Of Africa's New Ocean - with video
The only places where mid-ocean ridges appear above sea level are Ethiopia and Iceland.
Two new studies into the so-called “plumbing systems” that lie under volcanoes could bring scientists closer to predicting large
eruptions and reveal new information about where magma is stored and how it moves through the geological plumbing network.
Alien Species Living In The Inner Milky Way Could Be In Danger
Few people doubt there is intelligent alien life in the Milky Way galaxy, but where can we expect to find it?
Astronomers think that while the inner sector of the MIlky Way Galaxy may be the most likely to support habitable worlds.
Unfortunately some of these places are also most dangerous to all life-forms.
Black Holes With No 'Table Manners' Eat Two Courses At Once!
It is still unknown how the supermassive black holes (SMBH) in galaxy centres accrete gas and grow.
Researchers from the University of Leicester (UK) and Monash University in Australia have investigated how some black holes got so big so fast that they are billions of times heavier than the sun.
Mercury Surprises Scientists
On March 17, MESSENGER (MErcury Surface, Space Environment, GEochemistry, and Ranging) completed its one-year primary mission, orbiting Mercury, capturing nearly 100,000 images, and recording data
that reveals new information about the planet's core, topography, and the mysterious radar bright material in the permanently shadowed areas near the poles.
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).
Warp-Speed Planets Are Some Of The Fastest Objects In The Milky Way
Warped planets are some of the fastest objects in the Milky Way and they zoom through space near the speed of light.
Some years ago astronomers were astonished when they they found the first runaway star flying out of our Galaxy at a speed of 1.5 million miles per hour.
The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets?
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.
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.
Antarctica's Mysterious Lake Untersee And Its Otherworldly Ecosystem
A research team has now returned to Lake Untersee to begin the first real studies of this incredible environment.
This new high-quality image details the conical stromatolites that have formed on top of a boulder at a depth of about 20 meters, other
cones can be seen populating the sloping bottom...
