Colours of the Persian Gulf
This beautiful, natural-colour image of the small nation of Bahrain and parts of eastern Saudi Arabia was captured by the high-resolution multispectral instrument on the Copernicus Sentinel-2A satellite on 18 September 2015. The striking variations of blue represent the shallow versus deep waters, with the presence of coral reefs.
