Indian Ocean reveals deep secrets as submersible crafts descend 100 metres below waters of Seychelles

The Indian Ocean began to reveal some of its secrets today as the British-led Nekton mission deployed two submersible craft 100 metres below the waters of the Seychelles.

Live video showed shoals of fish deep-diving, an eel, spaghetti-like wire corals, and sponges encrusted on rocks.

Lucy Woodall, Nekton Mission principle scientist, described from inside one of the submersibles what she was seeing.

The submersibles were then due to descend further still, punching through undersea ocean currents to reach 200 metres.

The pictures were the first live, television-quality video images from a two-person submersible, a broadcasting world first.

Previous deep sea live streams cataloguing the world's oceans have been via fibre optic cable – today's broadcast used cutting edge wireless technology, sending video using LED light through the waves.

Video was transmitted using the blue region of the electromagnetic spectrum – removing the need for the submersibles and the scientists within to be tethered to fibre optic cables.
