Early next week, a submersible is expected to dive to 300 meters (nearly 1,000 feet) off the Seychelles in the Indian Ocean and send images to a satellite transmitter on the mother ship. The Associated Press will send that footage around the world.

Nekton - Mission - State - Oceans - Fears

The British-led Nekton Mission highlights the state of the oceans as fears grow over climate change. The Indian Ocean is the least explored in the world, and there is almost no data from the Seychelles below scuba depth. That's about to change.

The challenge is to transmit live video from the depths without restricting the free-roaming submersible. The solution turns the images into light, which is transmitted to a decoder suspended above the submersible and then sent to the mother ship via fiber-optic cable.

Clever - Bit - Streams - Video - Data

"The real clever bit is, we are now transmitting two high-bandwidth streams of video data from both of the submarines simultaneously and this has never been done before," said Darryl Newborough, whose company is behind the innovation.

Keeping two submersibles and the decoder, called a depressor, in the optimal configuration is a delicate task that...
