| Title |
Iceland Glacier Recession 1973 to 2000, Glacier Terminus contrast emphasized |
| Abstract |
This animation shows glacier recesion at the Breidamerkurjokull glacier in Iceland. The data from 1973 is taken from Landsat 1 and the 2000 data is from Landsat 7. The Breidamerkurjokull glacier in Iceland has been measured by Landsat to be receding since 1973. The glacierologists in Iceland and here at NASA's Goddard Space Flight Center have measured the recession throughout the entire glacier and found different rates of recession in different areas. In genral, the glacier seems to be receding at about 2% annually. It is extremely controversial whether this recession is caused by global warming. |

| Title |
Mt. St. Helens from Landsat: 1973 to 1992 |
| Abstract |
These images show Mt. St. Helens almost a decade before the May 18, 1980, eruption, approximately three years after the eruption, then a pair of images over the following decade, as the landscape recovered. Notice in particular the area northwest of the mountain, past the Toutle River, where forest coverage has recovered somewhat in the past ten years. North is up in all these images. The 1973 Landsat 1 image used MSS bands 7, 5, and 4 (called MSS 4, 2, and 1 on the later Landsat satellites) displayed as red, green, and blue respectively. The other images mapped TM bands 4, 3, and 2 to red, green, and blue. This color combination is often referred to as 'false color infrared' since it has a similar appearance and tone to color infrared photography. Reds represent vegetation (which is a strong reflector of near infrared light), greys are exposed land, and light blues show snow on the peaks of Mt. St. Helens and neighboring Mt. Adams. The Columbia River snakes into view in the lower left corner, just north of Portland, Oregon. |

Mississippi River Delta
| Title |
Mississippi River Delta |
| Description |
Time, weather, and human intervention have all shaped the Mississippi Delta [ http://landsat.usgs.gov/gallery/detail/389/ ] in Louisiana, a giant bird's foot shape protruding into the Gulf of Mexico. The Mississippi River deposits sediment into the ocean, and over 25 years, NASA Landsat satellites observed changes in the delta's shape. On June 10, 1976, Landsat 1 acquired the top image. On October 10, 2001, Landsat 7 acquired the bottom image. In the years that separated these acquisitions, the river delta saw retreating shorelines, inundations, and some additional new land. In the 2001 image, new land appears most conspicuously along the southwestern tip of the delta, on the southeast side of the waterway. Upstream, inundations appear along the river, where water has overflowed the riverbanks. The shoreline has also retreated south of the river. The 2001 image shows darker water in the river channel and more obvious brown sediments around the delta, but these differences may result as much from the enhanced imaging abilities of a newer sensor as from changes in the waterway. Left to their own devices, rivers change course over time, and the Mississippi is no exception. Geologists surmise that the Mississippi changed course numerous times over the past 10,000 years, wandering across a roughly 320-kilometer (200-mile) range along the Gulf Coast. The Mississippi probably settled on its current course some six centuries ago. Permanent human settlements created a strong desire to manage the river's behavior and end its meanderings. The U.S. Army Corps of Engineers constructed dams, locks, and canals to keep the river on one course. In the aftermath of the Hurricane Katrina, arguments intensified that the human management of the Mississippi River was a mixed blessing. The sediments the river carried offset the area's subsidence, [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17295 ] or sinking to a lower elevation. Placement of dams, however, stopped the sediment deposition, and also led to the loss of marshlands. Had coastal wetlands been present during Katrina and other hurricanes, they may have acted as a buffer against flooding by slowing the storm's giant waves and absorbing the surge of water that swept ashore with the hurricane.

| Title |
Early Landsat View of Los Angeles and Vicinity |
| Original Caption Released with Image |
Landsat 1 (originally named the Earth Resources Technology Satellite, or ERTS) was the first of what was to become a series of satellites designed to map and monitor the Earth's land surfaces. This view of Los Angeles and vicinity is a scene acquired by a single pass of Landsat 1 on 25 June 1974. The image is derived from visible and reflected infrared light and is displayed with the visible green, the visible red, and an infrared channel coded as blue, green, and red, respectively. Healthy vegetation is highly reflective in the infrared and therefore appears red in this standard display. Chaparral and forested areas form bold red patterns in the Sierra, Santa Monica, San Gabriel, and other mountain ranges. Agricultural fields form a textured red pattern in the San Joaquin Valley in the upper left. Downtown Los Angeles appears as a light blue patch in the lower right. |
