Title Dust Plume off the Coast of Sudan
Description *Dust Plume off the Coast of Sudan* On June 23, 2007, a dust storm began blowing off the coast of Sudan over the Red Sea. By the following day, the dust storm had expanded considerably, stretching across hundreds of kilometers in a southeastern arc. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took these pictures on June 23 (top) and June 24 (bottom). Besides showing the progress of the dust storm, the June 24 image looks generally fuzzier than the image from the previous day. This is probably not due entirely to dust. The image acquired on June 24 was near the edge of the satellite sensor's field of view. Because it was looking at the Red Sea at an angle that day, the sensor was also looking through a longer path through the atmosphere. Such oblique views can exaggerate the appearance of dust and smog. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

Title Dust Plume off the Coast of Sudan
Description On June 23, 2007, a dust storm began blowing off the coast of Sudan over the Red Sea. Dust continued blowing off the coast for the next several days. On June 28, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. This image shows two principal plumes blowing off the coast of Sudan, with numerous smaller plumes in between them. The plumes blow mostly toward the northeast, creating tan-colored blurs over the ocean surface below. Not all of the Red Sea's pale color, however, is due to dust. Some of its light appearance results from sunglint caused by the Sun's light reflecting off the ocean surface and directly back into the satellite sensor.

Jebel at Tair Eruption
Title Jebel at Tair Eruption
Description Jebel at Tair, a small volcanic island in the Red Sea, erupted late in the day on September 30, 2007, causing several casualties and leaving a number of Yemeni soldiers missing, according to news reports. A Canadian Navy spokesman, who was in the area at the time, described a "giant light show" with spewing lava and an ash cloud reaching hundreds of meters into the air. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the diminutive volcanic island on October 1, 2007. The haze over the ocean likely results from the eruption, probably a combination of ash and vog—volcanic smog that arises from the mixture of sulfur dioxide, oxygen, and moisture. North of the island appears an area of potentially disturbed water, perhaps caused by ash in the water and/or hot lava leading to water heating and discoloration. Midway between Yemen and Eritrea, Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions. The island is also known as Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, and Jazirat at-Tair. According to The Sydney Morning Herald, Yemen has maintained a military base since 1996 on this volcanic island, which is only about 3 kilometers (1.9 miles) long. Yemen's oil minister stated that earthquakes, registering between 4 and 4.3 in magnitude struck the island on September 30 and likely triggered the eruption.

Jebel at Tair Eruption
Title Jebel at Tair Eruption
Description Jebel at Tair, a volcanic island in the Red Sea, erupted at the end of September 2007. The eruption released lava and ash, and created a spectacular light show, according to observers in the area. On October 15, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite acquired this image. This shows a largely quieted volcano releasing only a faint volcanic plume. ASTER measures light visible to human eyes and infrared light, enabling the sensor to detect thermal anomalies caused by substantial temperature differences. The bright red spot at the summit is a thermal anomaly. A smaller, fainter anomaly appears just northwest of the summit. The volcano's slopes bear the marks of previous eruptions, the darker streaks indicating more recent lava flows.Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano—a cone composed of alternating layers of ash, lava, and rocks from earlier eruptions. The latest eruption is a continuation of activity on this island, where explosive eruptions were recorded in the eighteenth and nineteenth centuries. The volcano is known by multiple names and spellings, including Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, Djebel Teyr, and Jibbel Tir. You can download a 15-meter-resolution KMZ file of Jebel al-Tair [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Oct2007/jebelaltair_ast_2007288.kmz ] suitable for use with Google Earth.

Locust Swarms in Africa and …
Title Locust Swarms in Africa and the Arabian Peninsula
Description Alone, the desert locust is nothing to worry about. It is a solitary creature that stays out of sight munching on plants. But when enough locusts are packed into a small area, they form aggressive swarms that migrate from place to place, consuming all vegetation in their path. The transformation from solitary insect to plaguing swarm happens when conditions force the locusts into close confinement. Along the shores of the Red Sea, the locusts' winter breeding area, swarms develop when rain falls on the sandy soil to initiate the hatching of locust eggs. If conditions are right—plenty of water and vegetation for food—in the locust breeding areas, a large number of the insects hatch and form swarms. In March 2007, locust swarms were sighted in the coastal plains along the Red Sea coast in Sudan, Eritrea, Yemen, and Saudi Arabia, said Food and Agriculture Organization (FAO) of the United Nations in its Desert Locust Bulletin. [ http://www.fao.org/ag/locusts/en/info/info/index.html ] The small swarms were breeding in the lush vegetation left by abundant winter rains. As the vegetation dries, the swarms are likely to move north and inland, warned the FAO. While locusts are not visible from space, the conditions that allow swarms to develop are easy to spot. This image, created from data collected by the SPOT satellite, shows vegetation conditions. Dark green areas indicate that vegetation was more thick and lush in March 2007 than the average March between 1999 and 2006. Brown areas show where vegetation was more sparse than average. Strips of dark green line the shores of the Red Sea in the same areas where locust swarms were spotted. The image also shows that plants are flourishing inland in Sudan, Eritrea, and Saudi Arabia, where the locusts could migrate. Because such satellite images map the conditions in which locust swarms develop, scientists use them as an early warning to identify areas that should be monitored for locust outbreaks.

Locusts in Sudan
Title Locusts in Sudan
Description Rain is both a blessing and a curse in the deserts of northern Africa and southwest Asia. While water brings life, it also creates the conditions that bring crop-destroying locusts. On November 5, 2007, Locust Watch [ http://www.fao.org/ag/locusts/en/info/info/index.html ] of the Food and Agriculture Organization of the United Nations warned of an outbreak of desert locusts in Sudan. While not yet severe enough to cause extensive damage, the bands and small swarms of locusts had the potential to develop into more dangerous swarms. This image shows the conditions that allowed large groups of locusts to develop. The image is a vegetation anomaly image, and it shows plant growth between November 1–10, 2007, compared to average growth seen during the same period in 1998 through 2002 as recorded by the SPOT satellite. Strokes of green dominate much of Sudan in this image, indicating that plants were healthier, more numerous, or more lush than average. The green anomaly traces out the path of the Nile and Atbara Rivers. To the east of the Atbara River, a deep green streak surrounds the Gash River. Many of these areas, particularly the land along the Gash River, were submerged in floodwater for much of the summer. The rainy season of 2007 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14546 ] was unusually wet throughout Africa's Sahel. In Sudan, the heavy rain triggered widespread flooding [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14499 ], that persisted for months and left hundreds of thousands homeless. Only at the end of September did the rains ease and the land begin to dry. In the wake of the floods, plants clearly flourished. The combination of wet, sandy soil and plenty of food also allowed a large number of locusts to hatch. Locust Watch reported sightings of locust swarms—densely packed groups of locusts—along the Nile River and near the Gash River where the vegetation anomaly shows an ample source of food. As the vegetation in these regions dies throughout the winter dry season, the locusts will be forced into more small groups. Eventually, these groups will migrate north and east to the shores of the Red Sea, their winter breeding ground. Because a large group of locusts will likely be breeding, a potentially dangerous situation could develop on the western shore of the Red Sea, said Locust Watch. When a large number of locusts are forced into a small area, as could happen when the eggs hatch, the insects become an aggressive group, capable of migrating long distances, destroying crops and other plants in their path. According to Locust Watch, a small part of an average locust swarm can eat the same amount of food as 10 elephants, 25 camels, or 2,500 people in a single day.

Title Plume from Jebel at Tair
Description Jebel at Tair, a small volcanic island in the Red Sea, which had erupted [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14559 ] in late September 2007, released a volcanic plume on November 8, 2007. The Advanced Land Imager (ALI) [ http://eo1.gsfc.nasa.gov/Technology/ALIhome1.htm ] on NASA's EO-1 [ http://eo1.gsfc.nasa.gov/ ] captured this image the same day. In this image, volcanic plume appears as billowing puffs of white emanating from the summit. Evidence of earlier lava flows appears as dark stains on the volcano's slopes. Midway between Yemen and Eritrea, Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions.

Title Jason Celebrates 5th Anniversary as El Niño Builds, Warm Kelvin Wave Surges Toward South America
Original Caption Released with Image Recent sea-level height data from the Jason-1 altimetric satellite show that continuing weaker-than-normal trade winds in the western and central equatorial Pacific have triggered another strong, eastward moving, warm Kelvin wave. In the eastern equatorial Pacific, this "warm wave" appears as the large area of higher-than-normal sea surface heights (warmer-than-normal sea surface temperatures) between 140 degrees W and 110 degrees W. A series of these types of events that began in August 2006 have contributed to the present El Niño condition. ?In the American west where we are struggling under drought conditions, we welcome this modest, potentially rain-delivering El Niño,? said JPL oceanographer Dr. Bill Patzert. "The Jason-1 measurements are being used by several teams of international scientists to study the physics of El Niño to improve our ability to predict future events," said Dr. Lee-Lueng Fu, JPL Jason-1 project scientist. This image was created with data collected by the U.S./French satellite during a 10-day period centered on November 20, 2007. It shows a red area in the eastern equatorial Pacific that is about 10 centimeters (4 inches) above normal. These regions contrast with the western equatorial Pacific, where lower-than-normal sea levels (blue areas) continue that are between 5 and 13 centimeters (2 and 5 inches) below normal. Along the equator, the red sea surface heights equate to sea surface temperature departures greater than one to two degrees Celsius (two to four degrees Fahrenheit). This Jason-1 image shows sea surface height anomalies with the seasonal cycle (the effects of summer, fall, winter, and spring) and trend removed. The differences between what we see and what is normal for different times and regions are called anomalies, or residuals. When oceanographers and climatologists view these "anomalies" they can identify unusual patterns and can tell us how heat is being stored in the ocean to influence future planetary climate events. The U.S. portion of the Jason-1 mission is managed by JPL for NASA's Science Mission Directorate, Washington, D.C. Research on Earth's oceans using Jason-1 and other space-based capabilities is conducted by NASA's Science Mission Directorate to better understand and protect our home planet.
