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 and utilizing the "DSV Alvin". 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 deep, and of the seamount's surface was surveyed.
