January 6, 2012 - Rising Water Changes Caspian Sea Shoreline
While Caspian Sea water levels have historically fluctuated, the area has seen increasing water volume in the past two decades. These Landsat images show a small portion of the Caspian Sea shoreline, in 1985 and again in 2011. The Volga River is the dominant source of water for this inland sea, and heavy rains have greatly enlarged the flow into the Sea in the past decades.

December 28, 2011 - Arcadia Lake, Oklahoma
Arcadia Lake, a reservoir located just east of Edmond, Oklahoma, was constructed in the 1980s as part of the National Flood Control Act of 1970. Arcadia Lake was created to control floods in the Deep Fork River Basin, supply water to the city of Edmond, and provide recreational resources to the surrounding communities. Landsat images show the area in 1986, before the earthen dam blocked the Deep Fork River, and in 2011, with the reservoir near capacity.

December 24, 2011 - The Dead Sea
The Dead Sea is located in the Jordan Rift Valley and borders Jordan, Israel, and the West Bank. These Landsat images show the change in the Dead Sea from 1984 to 2011. In recent decades, diversion of water from the Jordan River, the sea's main tributary, has caused the Dead Sea to shrink. Mineral evaporation ponds that have replaced open water in the southern part of the sea can be seen in the 2011 image.

December 14, 2011 - The alluvial fans of the Mississippi River Delta Basin
The Mississippi River drains over two-thirds of the conterminous United States, sending an enormous amount of water through the Mississippi River Delta Basin in southern Louisiana. The river's velocity slows upon reaching the Gulf, reducing its capacity to carry suspended mud and sand, depositing the sediment in vast alluvial fans as shown in the Landsat 5 mosaic above. The fan deposits are major sources of petroleum, natural gas, and sulfur. This image was created using four Landsat 5 scenes acquired October 3 and November 11.
November 30, 2011 - West Virginia surface mining
Nearly half of the Nation's electrical power comes from coal burning; much of that coal comes from West Virginia. An increasing amount of coal extracted each year in West Virginal comes from surface and mountain top mining. The 1987 and 2011 Landsat satellite images above illustrate the expansion of surface mining in west central West Virginia. For more information, visit the EROS Image Gallery.
October 4, 2011 - Fires in the Savannah Grasslands of Australia's Northern Territory
Australia's normally dry interior was covered in thick grass that, after drying over the winter months, turned into an abundant source of fuel for the large fires burning throughout Australia's Northern Territory. The 2011 fire season is considered one of the most extreme in recent years. An example of the recent burn damage can be seen in the comparison of the September 7 and September 23 Landsat 5 images above.
September 23, 2011 - Rain helps suppress Pagami Creek Fire, Minnesota
Wet and cold weather is helping firefighters strengthen their grip on the Pagami Creek fire in the Boundary Waters Canoe Area Wilderness in northern Minnesota. Started by a lightning strike on August 18, the fire grew slowly and exploded into a major blaze September 11-12. Drawn from 28 states, firefighters continue to make steady progress against the fire. The September 19 Landsat 7 image above shows the nearly 94,000 acres burned.
September 16, 2011 - Pagami Creek fire, Minnesota
Hundreds of campers were evacuated from the 1.1 million-acre Boundary Waters Canoe Area Wilderness in northern Minnesota as the Pagami Creek fire continued to spread. Started by a lightning strike on August 18 about 14 miles east of Ely, Minnesota, the fire is the largest forest fire in Minnesota since 1918. The fire can be seen burning brightly in the September 12 Landsat 7 image above. Smoke from the fire has affected air quality as far away as Chicago.
September 14, 2011 - Bastrop County Complex Fire (Texas)
The Bastrop County Complex Fire, southeast of Austin, Texas, has consumed homes, agricultural land, and a state park. The distance from the northernmost part of the fire to the southernmost is more than 15 miles. The Landsat 5 images above show the area as it was on August 26 and the damage as of September 11. These images use mid-infrared and near-infrared bands in order to display burned vegetation clearly.
The "LUECKE" name that appears in the eastern portion of the image is a local man who left his name in trees for pilots to see as they come and go from the local airport (seen on the south edge of the image).
September 13, 2011 - Wildfires of Oregon
Multiple wildfires on the Warm Springs Reservation in the Cascade Mountains of Oregon can be seen in the Landsat 5 image acquired on September 9 (above). Started by a lightning storm on August 24, the freshly burned land appears as red, and vegetation is green.
