![]() While the rapidly melting ice on the coastlines have garnered the majority of the world’s attention, researchers are interested in the slow moving ice located in the middle of the continent as well. Covering more than 70 percent of Antarctica, the new map shows ice movement as small as 20 centimeters per year in speed and 5 degrees in annual flow direction. The goal of this data is to see how much ice is melting on the Antarctic continent and potentially to map the group beneath all this ice. The resulting map covers more than 70 percent of Antartica and shows shows ice movement as small as 20 centimeters per year in speed and 5 degrees in annual flow direction. This method has been shown to be 10 times more precise than other methods that have been used for measuring depleting sea ice in the past. Multiple satellite data (the Canadian Space Agency’s Radarsat-1 and Radarsat-2 the European Space Agency’s Earth remote sensing satellites 1 and 2 and Envisat ASAR and the Japan Aerospace Exploration Agency’s ALOS PALSAR-1) was compiled in order to view the Antarctic ice flow from multiple viewpoints. ![]() Researchers used synthetic-aperture radar (SAR) data to look at how the ice is moving and shifting. Using Synthetic-aperture Radar To Map Ice Movements As the climate continues to change, this ice is melting faster than ever and has the capacity to dramatically alter our world. This snow is compressed down into layers and layers of ice, creating shelves and glaciers that blanket the continent’s surface. ![]() Multiple satellites from different nations have now turned their lenses towards the icy continent of Antarctica to measure the rate of ice that is melting from the Earth’s southernmost pole.Īlthough Antarctica is classified as a desert, there is a small amount of snow and other precipitation that falls every year. Satellites are being used to map areas around the world that are notoriously remote and hard to reach. ![]()
