Ice takes a snapshot of the Arctic sea NASA's - Aqua - satellite

The Arctic Ocean is a growing sea ice dynamics of every winter falling and every summer reach its annual minimum size reduces each fall. While the minimum 2010 is to be seen, NASA's - Aqua - captures a snapshot satellite.

How the Aqua satellite "does" sea-ice? Microondas.Todo on the surface of the Earth - including persons - emitted radiation microwave properties of which according to the issuer vary, which Sensor microwave AMSR - E on Aqua map of the planet.

Ice emitted microwave instead of water, causing ice floating regions appear much brighter as the ocean open AMSR-E oceans sensor.This difference satellite capture one record allows sea ice throughout the year on the cloud cover, and the continuous night polar.Registros important are months because sea ice is dynamic.Melting and freezing, ice, moves with the wind and currents, to share or combined lead.

""AMSR-E data and other NASA satellites are fundamental to the understanding of the linkage between sea ice and the ocean and the atmosphere,"said Tom Wagner, Manager of the program of the Cryosphere in the NASA Washington headquarters."It is important for us, change these links to improve our predictive models like the world to understand.

Arctic sea ice is an important factor in the global climate system.Ice cool to reflect planet sunlight in space.Also help, the water warm Pacific Ocean flows, cold in the Arctic water salt that flows into the sea ocean Atlántico.El also fundamentally ocean circulation unit forms the Arctic ice; definition of the agencies that together make up its ecosystem and keep the heat from the Ocean since the merger of the frozen tundra to make.

In autumn 2009, Arctic sea ice minimum on 12 September and the third lowest satellite 1979.Los was, since measurements the microwave first at year changes was interested, can that be very variable so that scientists need many years, even decades, data, long-term trends to consider especially plazo.En, all the more important at least in the last decade took place in accordance with other research by NASA, which shows in January 2000 and December 2009 was the warmest decade in the Protocol.

Sea ice minimum 2010 nears end of this month, look for images and analysis of NASA and the national snow and data center of ice in Boulder, Colorado
