Multibeam bathymetry of Pao Pao Seamount (background) and an unnamed guyot (foreground) shows one example of nearby seamounts with very different geomorphology. Pao Pao Seamount comes to a very sharp peak at around 300 meters and shows steep flanks while the unnamed feature has a distinct flat top. Biological communities we find on these features may differ greatly at similar depth intervals despite being only 25 kilometers distant from each other.
