Explorers are set to deliver the first live video broadcast from deep below an ocean's surface. 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. 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.
