Minimize Bering Strait

The Copernicus Sentinel-1 mission takes us over the Bering Strait, which connects the Pacific and Arctic Oceans between Russia and the US state of Alaska.

The image was created by combining three radar scans of 11 December 2017, 23 December 2017 and 04 January 2018. Each image has been assigned a different colour: blue, red and green, respectively. This creates a colourful composite that highlights how the sea ice changed over the four weeks.

Since the Bering Strait lies slightly south of the polar circle, days are short during the winter. Thanks to its radar, Sentinel-1 can 'see' through clouds and in the dark, making it especially valuable for monitoring parts of the planet that endure relatively dark winter months. Offering this 'radar vision', images from Sentinel-1 can be used for charting icebergs and for generating maps of sea ice for year-round navigation
