THE world’s longest underwater chalk bank has been discovered off the coast of Norfolk.
Despite being less than ten metres below the surface and a short hop from the shore, it has lain undiscovered for 300 million years.
Some commentators have joked that the true reason that the chalk reef off Norfolk had been overlooked was its closeness to Cley and Trimingham, familiar places where wonders are unexpected.
But it is an important scientific discovery, made when divers surveyed what they thought was a small rocky plain earlier this year and uncovered towering arches of rock and deep chasms actually stretched for more than 20 miles.
Diver Rob Spray, 43, whose team discovered the reef, said: “It was like finding a natural Stonehenge hidden under the water.
“We couldn’t believe it when we found it was actually 20 miles long and had this amazing complex of gullies and arches. In some areas it looks like a moonscape.”
Three species never before recorded on the East Anglian coast have already been found there.
