2007 Arctic Sea Ice from AMS
…
| Title |
2007 Arctic Sea Ice from AMSR-E with Greenland in Foreground |
| Abstract |
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor which is not so sensitive to atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfall. This animation progresses at a rate of six frames per day from January 1, 2007 through the minimum extent which occurred on September 14, 2007. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures or divergence areas in the sea ice cover by warm brightness temperatures (in blue) while cold brightness temperatures, shown in brighter white, represent consolidated sea ice. The sea ice edge is defined by the 15% ice concentration contour in the three-day moving average of the AMSR-E 12.5 km sea ice concentration data while ice extent is the sum of all pixels with at least 15% ice. |

Arctic Sea Ice Maximum Concentrations 1979-2006 |
| Abstract |
This visualization shows the annual maximum amount of winter Arctic ice from 1979 to 2006. In 2005 and 2006, the winter ice maximum was about 6% smaller than the average winter ice over the 26 year period. The expected winter ice retreat is 1.5 to 2% loss per decade. The same data is also shown with a yellow region representing the cumulative or maximum extent of winter ice observed from 1979 to 2006. |

Sequence of Clouds, Snow Cover, Sea Ice, Sea Surface Temperature and Biosphere |
| Abstract |
This animation is part of an NSF-funded, international project, Exploring Time. The two-hour television special, broadcast on the Discovery Channel in the spring of 2007, explores how the world changes over different timescales ... from billionths of seconds to billions of years. This animation portrays a variety of remotely sensed data elements at different temporal resolutions. Initially, the animation shows cloud cover in motion over North America in half-hour increments from Nov. 26 to Dec. 7, 2005. The temporal pace quickens to show a 5-day moving average of daily MODIS snow cover along with daily AMSR-E sea ice from Dec. 7, 2005 to Mar. 15, 2006. As the view swings south over the Gulf of Mexico, the AMSR-E Sea Surface Temperature reveals warming ocean temperatures from March through August, 2006. As it passes over the Atlantic Ocean, the biosphere fades into view, showing both chlorophyll concentration in the ocean along with Normalized Difference Vegetation Index over the land areas. The biosphere animates over time while the view pans over northern Africa and Europe, showing data collected from September 2002 through February 2006. This program was also broadcast in Japan through a partnership with the NHK international broadcasting service and in France through a partnership with the ARTE television network. |

Loop of AMSR-E Daily Arctic Sea Ice from Aug 2005 to Aug 2006 |
| Abstract |
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. Sea ice is almost always in motion, reacting to ocean currents and to winds. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor and independent of atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfalls. This animation of AMSR-E 89 GHz brightness temperature in the northern hemisphere during late 2005 and early 2006 clearly shows the dynamic motion of the ice as well as its seasonal expansion and contraction. This animation shows the seasonal advance and retreat of sea ice over the Arctic from 8/5/2005 through 8/4/2006. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures in the sea ice by showing warmer areas of ice in a deeper blue and colder areas of sea ice in a brighter white. The sea ice extent is defined by a three-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%. |

| Abstract |
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. In this animation, the 2005 sea ice minimum extent is initially shown over the Arctic. As the 2005 minimum sea ice fades to orange, the 2007 minimum extent comes into view. The state of California, shown in green, is placed in the melt region for a comparison of the size difference between the two years.. |

Daily Arctic Sea Ice from August/September 2007 |
| Abstract |
In 2007, Arctic summer sea ice reached its lowest extent on record - nearly 25% less than the previous low set in 2005. At the end of each summer, the sea ice cover reaches its minimum extent and what is left is what is called the perennial ice cover which consists mainly of thick multi-year ice floes. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry as new shipping lanes open. This visualization shows 2007 daily Arctic sea ice from from 1 August through 19 September. |

Global Rotation showing Seasonal Landcover and Arctic Sea Ice |
| Abstract |
In this animation, the globe slowly rotates one full rotation while seasonal landcover and Arctic sea ice vary through time. The animation begins on September 21, 2005 when sea ice in the Arctic was at its minimum extent, and continues through September 20, 2006. This time period repeats six times during the animation, playing at a rate of day frame per frame. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Over the water, Arctic sea ice changes from day to day. |

At the end of each summer, the sea ice cover reaches its minimum extent and what is left is what is called the perennial ice cover which consists mainly of thick multi-year ice floes. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry as new shipping lanes open. This visualization shows the annual Arctic sea ice minimum from 1979 to 2007. A graph is overlaid that shows the area in million square kilometers for each year's minimum day. The 'previous record' and the '2007' record are highlighted. |
