English: A three dimensional echo sounding representation of a newly discovered canyon under the Red Sea by survey vessel HMS Enterprise.

A Royal Navy survey ship has produced a series of stunning images of a Grand Canyon-style ocean floor hidden deep under the Red Sea.

HMS Enterprise used her state-of-the-art surveying equipment to reveal the natural wonder during her nine-month mission to improve understanding of the waters east of Suez.

Discovering the 250 metre deep canyon after leaving the Egyptian port of Safaga the ship used her sophisticated EM1002 Multibeam echo sounder to create the 3D images, allowing the ocean floor to be seen for the first time.

Commanding Officer of HMS Enterprise, Commander Derek Rae, 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.

“It is, however, almost certain to say that this is the closest that humans will ever get to gaze upon these truly impressive sights hundreds of metres beneath the surface.”

The echo sounder, which is fitted to Enterprise’s hull, produces the images from the echoes returning from the sound pulses it sends out. This is a highly accurate way to measure the sea bed to determine if the depth of water is safe for navigation and shipping.

This was the first time HMS Enterprise has visited Safaga, which lies on the western shore of the Red Sea -approximately 250 miles south of Suez.

Safaga is the headquarters of the Egyptian Navy’s Red Sea Command and the ship’s company attended both formal and sporting events to ensure the regional links were kept strong.
