Seabase One
From Tardis Wiki, the free Doctor Who reference
Seabase One, nicknamed Atlantis, was a UNIT base in the Mariana Trench. It was the second UNIT facility in the area, with the first being in the ruins of Atlantis. The base was established by fish people operatives of UNIT, who made up some of the staff. It had an underwater research centre, a training facility for deep sea operations, and a Black Archive.
Liz Shaw served as the chief medical officer of Seabase One before her deployment to the UNIT Moonbase. (GAME: The Black Archive [+]Loading...["The Black Archive (game)"])
