A computer animation from Esa shows a map of the North Sea, including its offshore infrastructure and the height of waves
The video produced by the European Space Agency (Esa) shows a map of the North Sea, which also plots oil rigs, wind farms and large ships.
Radar instruments utilised by satellites are being used to forecast extreme wave heights that could endanger people and the environment.
They measure wind speed by looking at the surface of the sea from multiple angles as they fly over, to calculate how rough waters are as well as the height of waves.
In the animation, pale blue denotes calm waters, while bright purple indicates waves of up to 49ft (15metres) high and it is possible to see how areas of rough sea ripple in different directions
