In Pictures: Envisat - One Earth Year
Oil Spill

Envisat watched the Prestige tanker spill its cargo of oil off the northwest coast of Spain in November last year.

The Advanced Along-Track Scanning Radiometer (AATSR) instrument on board Envisat was used to track the slick.

Prestige is the white dot in the bottom left of the image, from which oil can be seen leaking.
