Title Growing-Season Fires in Central United States
Description Agricultural burning in preparation for the growing season was underway in the central United States at the time of this image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on March 31, 2004. Across the dun-colored witner landscape, spring green is beginning to spread across the south-central parts of the country, including (top left to bottom) Kansas, Oklahoma, and Texas, and (top right to bottom) Missouri, Arkansas, and Louisiana. Fires have been marked with red dots in the image. The smokier fires in Arkansas may be prescribed burns on state or federal lands that are set in the spring to decrease built-up underbrush and other vegetation that could contribute to more severe wildfires later in the season. Though not necessarily hazardous, large-scale burning can have an impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 500 meters per pixel.

Title Hurricane Katrina Erodes the U.S. Gulf Coast
Description The graceful curve of the Chandeleur Islands resembles a multi-boned spine connecting the Mississippi Gulf coast to the delta of the Mississippi River in Louisiana. Like all barrier islands, the Chandeleur Islands form a thin protective wall between the open sea and the mainland, in this case Louisiana's St. Bernard Parish. The islands absorb the strongest waves, sheltering the mainland during large storms. It is no surprise, then, that barrier islands along the U.S. Gulf Coast changed dramatically in the wake of Hurricane Katrina, and no change is as dramatic as that seen in the Chandeleur Islands. Hurricane Katrina's strong winds, storm surge, and battering waves scoured the islands, leaving them reduced or gone altogether. These images of the islands were taken by the Landsat 5 satellite. The top image, taken on September 16, 2005, shows the Mississippi and Alabama coast line, including the line of islands that bore the brunt of Katrina's fury. The lower images show the northern section of the Chandeleur Islands at full resolution. In the 11 months that passed between October 15, 2004, when the right image was taken, and September 16, 2005, when the left image was taken, the islands have wasted away. Barrier islands like the Chandeleur Islands are constantly building, eroding, and shifting under the normal actions of wind and waves. A powerful storm like Katrina can produce changes that otherwise may have taken many years, and most of the change seen here is probably a result of Katrina. Hurricane Dennis also gave the islands a glancing blow on July 10, 2005, and may be responsible for some of the change. The other barrier islands shown in the top image were also scoured by Katrina. The large images show that the Ship Islands [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13130 ] are now significantly smaller than they were in 2004, and Dauphin Island [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13132 ] has been cut in two. To read more about Katrina's impact on the Gulf Coast, please visit the United States Geological Survey's Hurricane Katrina Impact Studies [ http://coastal.er.usgs.gov/hurricanes/katrina/ ] page.

Title Fires Across Southern United States
Description This image of fires in the southern United States was captured on March 10, 2004, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Actively burning fires have been marked with red dots in Oklahoma (top left), Texas (bottom left), Arkansas (top center), Louisiana (bottom center), and (left to right across the rest of the image) Mississippi, Alabama, Florida, and Georgia. Most of us don?t think of late winter as fire season in the United States, but according to the Southern Coordination Center for the National Interagency Fire Center, just over 993,000 acres had been affected by fire in the Southern region as of March 23, 2004: 11,936 human-caused fires affected 130,385 acres, 18 lightning-caused fire affected 225 acres, and 1,084 prescribed fires (those set by land management agencies for natural resource management purposes) affected 862,772 acres. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Title Phytoplankton Bloom in the Gulf of Mexico
Description . NOTE: All SeaWiFS images and data are for research and educational use only. All commercial use of SeaWiFS data must be coordinated with ORBIMAGE [ http://www.orbimage.com/ ]., A dark green plume of phytoplankton extends away from the crow?s foot of the Mississippi River Delta in this image, acquired on December 13, 2004, by the Sea-viewing Wide Field-of-view (SeaWiFS) Sensor flying on the OrbView-2 satellite. Phytoplankton blooms usually occur where cold water rushes up from the bottom of the ocean carrying nutrients to sunlit waters. In this case, the bloom may be related to recent flooding along the Mississippi River and its tributaries. Heavy rains early in December triggered floods [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12619 ] across the southeastern United States. The draining flood water carried agricultural run-off into the Mississippi River and the Gulf of Mexico, and that may have provided the nutrients the microscopic ocean plants needed to thrive. In the above images, the Red River twists across southeastern Louisiana from the upper left corner and pours into the Mississippi River beneath the cloud bank. Also concealed by clouds, the Mississipppi drains into the Gulf of Mexico, but just beyond the river?s mouths, the Gulf of Mexico is green with phytoplankton. The lower image shows high chlorophyll concentrations, yellow, corresponding to the green bloom. Scientists have suspected that phytoplankton blooms such as this one may be connected to agricultural run-off, and a recent study seems to confirm this. Using images from NASA?s SeaWiFS sensor, scientists from Stanford University?s School of Earth Sciences compared the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico?s Sea of Cortez (Golfo de California) and found a close correlation. (See press release [ http://www.stanford.edu/dept/news/pr/2004/agugulf-0112.html ] for more information.) Phytoplankton blooms occurred in the Sea of Cortez shortly after irrigation along the coast carried fertilizers and other agricultural run-off into the sea. The bloom detected in the Gulf of Mexico on December 13 may be similarly linked to agricultural run-off. Phytoplankton are an important source of food for many marine animals, so waters that are rich in phytoplankton usually support a thriving ecosystem. But in some cases, phytoplankton blooms can be deadly to the very ecosystem they typically support. Some blooms, such as red tide, are toxic and result in wide-spread fish deaths. Large blooms can also create dead zones in the ocean?oxygen-poor regions where fish cannot survive? when the plants die. The bacteria that break down the decaying plants consume all of the oxygen, leaving a dead spot. The Gulf of Mexico is annually plagued with one such dead zone every summer near the location of the current bloom.

Title Smoke from Alaskan Fires over Louisiana
Description This image of the southern United States from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite is a picture-perfect example of what meteorologists mean when they describe the atmosphere as a fluid. In the center of the image, an airborne river of smoke from fires raging across Alaska is flowing down the Mississippi River corridor and spreading out across the shoreline of the Gulf of Mexico, at the bottom of the scene. Thick smoke hangs over Louisiana (bottom center) as well as Texas, to the west, and Arkansas to the north. MODIS captured the image on July 19, 2004.

Title April Showers Bring May Flowers to the Southern United States
Original Caption Released with Image Vigorous vegetation growth in the Southern United States after heavy rains fell during April and early May, 2004, is quantified in these images and data products from the Multi-angle Imaging SpectroRadiometer (MISR). The images were acquired on April 1 (top set) and May 3 (bottom set), and extend through Kansas and Missouri, Oklahoma and Arkansas, and eastern Texas, with the Texas-Louisiana border at the bottom right-hand corner. The left-hand images are natural-color views from MISR's nadir camera. In the month between the April and May images, the overall greenness is enhanced, and the Boston and Ouachita Mountains are transformed from brownish hues to vivid green. The city of Dallas, Texas, appears as the pale gray area at lower left and the Red River (which corresponds with the Texas-Oklahoma border) is apparent as the yellowish feature flowing toward the lower left-hand edge. Scattered clouds appear in the upper right-hand corners of both images. Quantitative values for the vegetation changes are provided by the center and right-hand images. The middle panels show Leaf Area Index (LAI), or the area of leaves per unit area of ground below them, as measured from above. The right-hand panels show FPAR, which is the fraction of the photosynthetically active region (PAR) of visible light (400 - 700 nm) absorbed by green vegetation. LAI and FPAR are two important quantities for monitoring the photosynthetic activity and carbon uptake efficiency of live vegetation. MISR's LAI and FPAR products make use of aerosol retrievals to correct for atmospheric scattering and absorption effects, and use plant canopy structural models to determine the partitioning of solar radiation. Both of these aspects are facilitated by the multiangular nature of the MISR measurements. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. These data products were generated from a portion of the imagery acquired during Terra orbits 22810 and 23276. The panels cover an area of about 380 kilometers x 704 kilometers, and utilize data from blocks 61 to 65 within World Reference System-2 path 26. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.
