This cruise would be followed by a more extant expedition, covering all of the Patton seamounts, in 2002, for which the Patton cruise served as a model. 8 dives were conducted during the cruise, the deepest being 3,375 m (11,073 ft) deep, and 86,718 m (933,425 sq ft) of the seamount's surface was surveyed.

Seamount, like many other seamounts, serves as an "oasis of life" for resident organisms. Isolated populations found on seamounts like Patton have

Limited-scale fishing operations and scientific investigations were carried around in the 80s and 90s, mostly due to the rough nature of the seamounts, and the difficulty of sampling at such depths. July 1999 marked the first detailed observations on the seamount, in an expedition based on the
