There's another nonprofit in this space, Inkfish.

They have a highly advanced deep sea research vessel called the Pressure Drop, and another called the Hadal Exploration System.

Do you know who owns Inkfish? Gabe Newell of Valve fame!

There's also the Ocean Exploration Trust, founded by Robert Ballard of Titanic discovery fame (among _many_ other things).
