Explorers reveal secrets of underwater ‘Grand Canyon’
A five-week expedition to map and sample a giant underwater canyon off the northwest coast of Morocco has completed its mission, yielding the best look yet at the deep-sea wonder.
More than half a mile (about 1 kilometer) deep, 280 miles (450 km) long and up to 20 miles (30 km) wide, Agadir Canyon is approximately the size of the Grand Canyon. A joint team of British and German scientists aboard the German research vessel Maria S Merian took images and samples of the seafloor to create a high-resolution 3D map of the canyon and sample its marine life.
Up until now, Agadir Canyon, considered by some measures the world’s largest undersea canyon, has rarely been explored, said British expedition leader Russell Wynn of the National Oceanography Centre in England. “There are a lot of interesting features that no one has ever gone and looked at,” Wynn continued.
Long flows of sediment carved out the canyon over millions of years, much like a river carves out a canyon, including the Grand Canyon, on land. Researchers had mapped Agadir Canyon previously at a very crude scale that revealed features a few hundred meters big. Now, using a technology called multibeam sonar, Wynn and his colleagues have mapped the region on the scale of a few meters to tens of meters.

Over the next 12 months, specialist scuba holiday company Dive Worldwide will be supporting Bite-Back Shark & Marine Conservation with donations collected from client bookings to any one of its stunning dive destinations around the world. The independently-owned operator expects to raise £3000 for the UK charity.
Manager at Dive Worldwide, Phil North, said: “We’re especially excited to work with Bite-Back and support its intelligent, creative and results-driven campaigns to end the UK trade in shark products and prompt a change in attitudes to the ocean’s most maligned inhabitant.”
Bite-Back is running campaigns to hold the media to account on the way it reports shark news along with a brand new nationwide education programme. Last year the charity was credited for spearheading a UK ban on the import and export of shark fins.
Campaign director at Bite-Back, Graham Buckingham, said: “We’re enormously grateful to Dive Worldwide for choosing to support Bite-Back. The company’s commitment to conservation helps set it apart from other tour operators and we’re certain its clients admire and respect that policy. For us, the affiliation is huge and helps us look to the future with confidence we can deliver against key conservation programmes.”
To launch the fundraising initiative, Phil North presented Graham Buckingham with a cheque for £1,000.
