This image shows the Easter coast of Greenland, the largest island in the world.
Its centre is a huge plateau of ice of with a maximum thickness estimated to more than 3 km. It constitutes an important water reservoir for the planet.
On this image, the near infrared channel (865 nm) of MERIS enables a clear separation of atmospheric features ( the red hues) and ice feature ( the green hues). Along the coast, the currents create vortexes in the melting ice sheet.
