The starboard side of the HUGO junction box in its new home on Loihi seamount. Experiments are installed and repaired via the Pisces V submersible.

A synaphobranchid visits the HUGO junction box. The actions of the submersible during repairs in January 1998 caught the interest of the ubiquitous shrimps and eel-like fishes like this one on Loihi's summit. Also visible here is the fine, gelatinous mud in which HUGO sits. The mud is easily disturbed and quickly limits visibility.
