Layers of frozen sea water, known as sea ice, cap the Arctic Ocean. The ice grows dramatically each winter, and melts just as dramatically each summer. In the past decade, the melting has grown more dramatic, while growth has become less so, as you can see in our World of Change feature.
The pair of images above shows Arctic sea ice concentrations for September 2010 (left) and March 2011. The yellow outline shows the median sea ice extent observed by satellite sensors in September and March from 1979–2000. “Extent” is the total area with an ice concentration of at least 15 percent. The maps were compiled from observations by the Defense Meteorological Satellite Program and by the Advanced Microwave Scanning Radiometer for EOS (AMSR-E), on NASA’s Aqua satellite. The sensors measure microwave energy radiated from Earth’s surface, as sea ice and open water emit microwaves differently.
On September 19, 2010, Arctic sea ice reached its annual minimum, at 4.60 million square kilometers (1.78 million square miles). The National Snow and Ice Data Center (NSIDC) declared 2010 to be the third-lowest Arctic sea ice extent in the satellite record.
In March 2011, after a winter of growth, sea ice extent in the Arctic was the second lowest for the month of March since satellite records were first kept in 1979. NSIDC reported the overall ice extent at 14.56 million square kilometers (5.62 million square miles) at the maximum on March 7. Concentrations remained below normal in both the Atlantic and Pacific sectors of the Arctic, particularly in the Labrador Sea and the Gulf of St. Lawrence.
New data showed that the amount of older, thicker ice had increased slightly over last year. “Data through the third week of March shows an increase in sea ice one to two years old, and older than two years old, compared to recent years,” NSIDC noted. “However, the amount of older ice remains much lower than in the mid-1980s, and there is still almost none of the oldest ice (older than four years) that used to dominate much of the Arctic Ocean.”
Including 2011, the March trend in sea ice extent has been decreasing at a rate of 2.7 percent per decade. Visit World of Change: Arctic Sea Ice to see the trend since 1999.

Late on May 2, 2011, in an effort to spare Cairo, Illinois, the U.S. Army Corps of Engineers used explosives to breach a protective levee near the confluence of the Ohio and Mississippi Rivers. As predicted, the two-mile hole in the levee flooded 130,000 acres of nearby farmland in what is known as the Birds Point-New Madrid Floodway.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured these images of the area on May 3, 2011 (top), and April 29, 2011 (bottom). Both images use a combination of visible and infrared light to increase constrast between water and land. Water ranges in color from electric blue to navy. Vegetation is green. Clouds are pale blue-green and cast shadows onto the land surface below.
Tiny squares of green in the April 29 image show that the floodway consists of farmland. The image from April 29 also shows flooded conditions along the Ohio and Mississippi Rivers. (See an image from 2010 for a comparison.) In the image acquired on May 3, the floodway downstream of Cairo is submerged. The same day that MODIS acquired the image, the Advanced Hydrological Prediction Service of the U.S. National Weather Service reported that the water level for the Ohio River at Cairo had dropped, although it still remained at major flood stage.
