Royal Navy Ship Discovers Uncharted Red Sea Canyon - 11/03/2013


HMS Enterprise, a multi-role survey vessel - hydrographic oceanographic (SVHO) of the British Royal Navy, has recently produced a series of stunning images of a Grand Canyon-style ocean floor hidden deep under the Red Sea. The vessel used her 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 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, commented 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 almost certain 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.

It 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 regional links are strongly maintained.

HMS Enterprise will remain in the Middle East until the summer, building on the successes of her sister ship HMS Echo, which discovered numerous wrecks and obstacles during a 19-month deployment to the same region.
