These bird's eye photographs show how a sandbank off Great Yarmouth has changed over the last ten years due to shifting sands.
Taken by aerial photographer Mike Page, the images of Scroby Sands in May 2012, December 2017 and April 24 this year reveal how it keeps being reshaped.
The latest picture shows how the sand bank has become crescent-shaped.
It was reported the teenager managed to cross and get back in two hours eight minutes and 50 seconds.
The currents around Scroby Sands are treacherous.
The Scroby Sands Offshore Wind Farm is 2.5km offshore and was commissioned in 2003. It is made up of 30 towering turbines.
