Although they had built an industrial infrastructure and undersea dwellings, most Moneans still chose to live as their ancestors did, aboard ships. The Moneans possessed limited knowledge of the deep regions of their home, as their best research vessel could only dive 100 kilometers while the Waters' center was 600 kilometers deep. Unfortunately, the ocean eventually began to lose containment, at a rate that would have resulted in its complete dissipation by 2380. An image of the Monean city was sometimes seen on the large astrometrics monitor aboard Voyager. (VOY: "The Voyager Conspiracy")
