ICESat Lithograph
| Title |
ICESat Lithograph |
| Abstract |
This still image was generated to be printed as a lithograph for public distribution. [from the litho:] This image illustrates ice sheet elevation and cloud data from ICESat's Geoscience Laser Altimeter System (GLAS) on its first day of operation, February 20, 2003. On that day, the instrument collected a 1064 nm wavelength profile across Antarctica: the lower West Antarctic Ice Sheet in the foreground is separated from the higher East Antarctic Ice Sheet in the background by the steep TransAntarctic Mountains. The elevation profile (in red) is depicted relative to the Earthandapos;s standard ellipsoid with 50x vertical exaggeration. Data collected across floating sea ice and open water of the adjacent Southern Ocean cannot be shown at this scale. Clouds of various thicknesses are indicated by colors changing progressively from light blue (thin clouds) to white (opaque layers). Note that the laser cannot penetrate the thickest clouds causing gaps in the elevation profile below. The RADARSAT (Canadian Space Agency) mosaic is used to illustrate the Antarctic continent. |

Iceberg B-15A: Sample Composite |
| Abstract |
A 100 mile long iceberg, named B-15A, cracked in two between October 7th and 9th, 2003. B-15A broke off Antarctica's Ross Ice Shelf in 2000. Since its calving in 2000, it has made delivery of fuel and supplies to McMurdo Station difficult. |

Floods in Gonaives, Haiti
| Title |
Floods in Gonaives, Haiti |
| Description |
The month that has passed since Tropical Storm Jeanne flooded Haiti has allowed time for a closer look at the tragic flooding. While the floods that killed over a thousand in Gonaives were initially easy to spot, this analysis shows how much more of the northwestern arm of the island was affected. The image compares synthetic aperture radar (SAR) data collected by the RADARSAT-1 satellite (Canadian Space Agency) on September 24 and 30 to data collected on July 16, 2003. The changes have been color-coded and superimposed on a Landsat-7 scene, taken on July 3, 2003. Marbled veins of color across the entire region reveal extensive flooding. In the above image, areas that were dry on September 24, but flooded on September 30 as flood waters advanced and drained, are colored blue. Regions that were flooded between September 24 and September 30 are pink, and areas that were flooded on the 24th, but drained by the 30th are colored red. Landslides and regions that were covered with sediment after flash floods coursed through are green. Grey land shows where no changes were detected. Though grey seems to dominate the image, a close look shows that most of the northwestern peninsula was affected by the floods. Since the region was one of the primary crop areas in Haiti, the widespread flooding could have a lasting impact on the country.

Flooding along the River Gash in Sudan |
| Description |
This RADARSAT-1 image shows the aftermath of heavy flooding along the Gash River in the east African countries of Sudan and Eritrea (described by an alternate spelling, "Erythrea," in the image). The rain-induced floods lasted from July 28 to August 21, 2003. At the flood's height, 79 percent of Kassala city, Sudan, was flooded, leaving 80 percent of the population homeless. The region also suffered heavy losses in agriculture. In this image, taken on August 24, 2003, by the Canadian Space Agency and Radarsat International, blue tones show areas that have been flooded. Red areas are regions where the soil has excessively high moisture content. Agriculture in this area is likely to be damaged. Lighter red tones along the river correspond to sedimentation and light blue tones show eroded terrain. In urban area, blue tones show where houses have been destroyed. The dark grey areas have not been affected by the floods. Image courtesy of ParBleu! Inc. and the Canadian Space Agency. |

Ward Hunt Ice Shelf
| Title |
Ward Hunt Ice Shelf |
| Description |
The Arctic?s largest ice shelf is breaking up. The Ward Hunt Ice Shelf is a remnant of the compacted snow and ancient sea ice that extended along the northern shores of Ellesmere Island in Northern Canada until the early twentieth century. Rising temperatures have reduced the original shelf into a number of smaller shelves, the largest of which was the Ward Hunt Ice Shelf on the northwest fringe of the island. The Ward Hunt Ice Shelf encompasses Ward Hunt Island and covers the mouth of the Disraeli Fiord. Until recently, fresh melt water formed a 43-meter deep lake on top of almost 400 meters of seawater in the fiord. Called an epishelf lake, the relatively fresh water dammed by the 3000-year-old ice shelf became the basis of a rare ecosystem. Disraeli Fiord was the largest remaining epishelf lake in the Northern Hemisphere. Between 2000 and 2002, the Ward Hunt Ice Shelf began to crack and eventually broke in two, allowing the lake behind it to drain rapidly into the Arctic Ocean. Derek Mueller and Warwick Vincent, of the Centre d?études nordiques at Université Laval in Quebec, Canada and Martin Jeffries of the Geophysical Institute at the University of Alaska Fairbanks in Fairbanks, Alaska described the event in a paper published in Geophysical Research Letters [ http://dx.doi.org/10.1029/2003GL017931 ] on October 18, 2003. This Standard Beam Mode RADARSAT-1 image clearly shows a large crack dividing the ice shelf in half. The crack runs from the Arctic Sea to the right of Ward Hunt Island and the bright white ice grounded there and back to the rougher, mountainous region. The image, acquired September 27, 2003, has a resolution of 25 meters. Image courtesy RADARSAT International [ http://www.rsi.ca/home.htm ].
