\nThe Copernicus Sentinel-1 mission gives us ‘radar vision’ over part of Antarctica’s third-largest island, Thurston Island.\n<\/p>\n

\nThe satellite’s radar can ‘see’ through clouds and in the dark, making it a valuable tool for monitoring polar regions which are prone to bad weather and long periods of darkness – such as Antarctica.\n<\/p>\n

\nThis image combined three passes by Sentinel-1’s radar in March, April and May 2017. Each was assigned a colour – red, green and blue – and when merged, changes between the acquisitions appear in various colours.\n<\/p>\n

\nThe ice-covered island appears grey, showing no change over the three-month period. But changes in sea ice in the upper part of the image appear as speckles of green, red and blue.\n<\/p>\n

\nIn the lower part of the image we can see part of the Abbot Ice Shelf appearing in light blue.\n<\/p>\n
