Images above: The images above shows a comparison of the same Antarctic scene from two different NASA remote sensors. "It's able to record subtle variations in the ice sheet's surface that tell us more about ice sheet features, the flow of the ice sheet and changes in the ice sheet's surface." "The resolution sensitivity of the Landsat sensor is well beyond that of even the most state-of-the-art digital camera," Bindschadler said. The research group will continue to roll out additional images through this summer. This site contains original images and close-ups of various areas of Antarctica, all available for download. Researchers at NASA, the USGS, and the British Antarctic Survey in Cambridge, U.K., with support from the National Science Foundation, have launched a Web site offering public access to the image mosaic. Bindschadler oversaw the selection of the scenes used to create the mosaic. "These images give us incredibly detailed views of the Antarctic ice sheet surface and serve as maps for many locations that have never been mapped before," said Robert Bindschadler, chief scientist of the Laboratory for Hydrospheric and Biospheric Sciences at NASA's Goddard Space Flight Center, Greenbelt, Md. The single continent-wide map, called the Landsat Image Mosaic of Antarctic (LIMA), offers views of the coldest continent on Earth in 10 times greater detail than possible before. As can be seen in this sample Landsat image of the area around McMurdo Station, LIMA will show ice shelves, mountains, glaciers, coastlines, and many of the other features that make Antarctica a fascinating and important place to study. Image right: The Landsat Image Mosaic of Antarctica (LIMA) will show the Antarctic continent for the first time in high-resolution, true-color satellite images. These extraordinary images provide a stunning bird's eye view of the icy mass that has been the focus of science, myth and storytellers' imaginations alike. Geological Survey (USGS) have woven together more than a thousand images from the Landsat 7 satellite to create the most detailed high-resolution map ever produced of Antarctica. This caught the team off guard, as they had not expected to find any type of life this far below the icy surface.Researchers from NASA and the U.S. But after refocusing the camera, they realized that the lens was being swarmed by tiny crustaceans known as amphipods. Initially, the team thought their equipment was faulty. When the researchers sent a camera down through the icy tunnel and into the cavern, hundreds of tiny, blurry flecks in the water obscured the video feed. ![]() The team drilled down around 1,640 feet (500 meters) below the ice's surface using a powerful hot-water hose to reach the underground chamber. Satellite photos showed an unusual groove in the ice shelf close to where it met with the land, and researchers identified the peculiar feature as a subsurface river, which they described in a statement. ![]() The scientists found the secret subterranean habitat tucked away beneath the Larsen Ice Shelf - a massive, floating sheet of ice attached to the eastern coast of the Antarctic peninsula that famously birthed the world's largest iceberg in 2021.
