“HMS Enterprise found the 250m-deep canyon in the Red Sea during a nine-month mission to improve understanding of the waters east of Suez. The 3D images were created after the vessel left the Egyptian port of Safaga and were made using a multibeam echo sounder.
Derek Rae, commanding officer of HMS Enterprise, said: “These features could be the result of ancient rivers scouring through the rock strata before the Red Sea flooded millennia ago.
“Some may be far younger and still in the process of being created by underwater currents driven by the winds and tidal streams as they flow through this area of the Red Sea, carving their way through the soft sediment and being diverted by harder bed rock. Or there is always the possibility that they are a combination of the two.”
