Australian researchers have investigated signs of geological structures hidden behind the Great Barrier Reef in Queensland, and have found a much deeper reef spanning more than 6,000 square kilometres (2,316 square miles).

New seafloor maps of the area have revealed a vast, underwater field of doughnut-shaped mounds, each one measuring 200 to 300 metres (656 to 984 feet) across, and some as much as 30 metres deep.

UPDATE: Great Barrier Reef

One of Australia’s most important natural assets, the Great Barrier Reef (GBR), is being affected by the worst ever bleaching in its history, amid warmer than average water temperatures associated with this summer’s major El Niño event and against a background trend of ongoing ocean warming.

With extensive coral bleaching having been predicted as far back as October last year, Terry Hughes at the ARC Centre of Excellence for Coral Reef Studies convened the National Coral Bleaching Taskforce to document the bleaching, both from the air and at close quarters. With our survey work still ongoing, a bleak picture is emerging: more than 1,000 km of the Great Barrier Reef shows signs of significant bleaching.
