Indian Ocean exploration mission makes historic broadcast

A British-led scientific mission to document changes taking place beneath the Indian Ocean has broadcast its first live, television-quality video transmission from a two-person submersible.

Monsoon storms and fierce underwater currents continue to present a challenge at greater depths as scientific work begins in earnest on Tuesday.

The first transmission came from 60 meters (200 feet) down. Previous deep-sea livestreams cataloguing the world's oceans have been via fiber-optic cable. The new broadcast uses cutting-edge wireless technology, sending video optically through the waves.

The Associated Press is the only news agency working with British scientists from the Nekton research team on its deep-sea mission that aims to unlock the secrets of the Indian Ocean, one of the world's least explored areas.
