Located between the French island of Corsica and the Italian island of Sardinia, the Strait of Bonifacio is pictured here thanks to the European Space Agency’s Envisat.
The French island if Corsica is shown above, and Sardinia on the bottom, with the Strait of Bonifacio running in between. The image was created by combining three Envisat Advanced Synthetic Aperture Radar (ASAR) acquisitions (19 April, 1 March and 18 February 2011) over the same area. The colours result from changes in the surface between acquisitions.
