This possible volcanic ridge extends eastward from Liszt Seamount and was imaged during overnight mapping operations on NOAA Ship Okeanos Explorer conducted by NOAA Ocean Exploration during the Deep-Sea Symphony: Exploring the Musicians Seamounts expedition. The ridge feature is coincident with one of the fractures in the Murray Fracture Zone. If volcanic, this bathymetric observation would support a hypothesis that melts ascending at Liszt Seamount may have been exploiting the structural weakness of the fracture zone to ascend to the surface, lending insights into the complex geologic history of the region.
