Glitter helps to monitor ocean waves
20 March 2017
The notion of glitter might appear as somewhat frivolous, but scientists are using Sun glitter in images from the Copernicus Sentinel-2 mission to map the motion of the sea surface.
Created by wind blowing across the surface, wave patterns are complex and highly varied. Being able to predict their movement can greatly benefit mariners, port and rig builders, coastal farmers and more.
Since measurements of waves from buoys and ships are limited in numbers and in coverage, satellites provide the answer over the oceans. As well as the well-established use of measurements of roughness from satellite sensors, Sentinel-2's multispectral camera can also have an important role to play in mapping ocean waves.

Rapid acceleration of an Arctic glacier over the past year has been detected by the Copernicus Sentinel-1 satellites.
Sitting on Norway's Spitsbergen island in the Svalbard archipelago, the Negribreen glacier has recently seen a surge in ice surface speed, increasing from 1m to13m a day over the winter.
