[...] In December, explorer and investor Victor Vescovo, along with scientist Alan Jamieson from Newcastle University, are embarking on a groundbreaking mission more than 6.5 miles under the waves. The two are heading out in a new $48 million dollar submarine system to better map the bottom of the world's five oceans.
They're calling the mission, which will be the first time people travel to the bottom of each of the world's seas, "Five Deeps."
"Our depth of ignorance about the oceans is quite dramatic," Vescovo said as he introduced the mission to an audience in New York. "Four of the oceans have never even had a human being go to their bottom. In fact, we don't even know with great certainty where the bottom of the four are."
First up on the five-dive trip will be the Puerto Rico Trench, the deepest point in the Atlantic Ocean. It's a spot no human has ever explored, and it's so deep that any communications from the submarine will take seven seconds to travel back up.
The team believes it's possible to find a location deeper than the Challenger Deep.

I've looked at the text and pictures on Triton Subs web site http://tritonsubs.com/hadal/ [tritonsubs.com] and do not see any evidence of a fibre optic tether.
The Triton 36000/2 appears to be completely free of any surface support other than deployment, retrieval, and maintenance aboard the support vessel.
