More Information
Summary:E/V Nautilus expedition Lu'uaeaahikiikapapaku (NA134) ROVs Hercules and Argus along with the ship's EM302 multibeam sonar to explore the Voyager Seamounts located in the southern "expansion" area of Papahanaumokuakea Marine National Monument (PMNM). The lineation of these seamounts suggests they could be a southerly extension of the poorly delineated Wentworth seamount chain located north of the Hawaiian Ridge. Given the lack of geochemical constraints and age determinations of these seamounts, they tentatively hypothesize that they are an extension of the Wentworth chain comprising an age-progressive seamount track. A major focus of the expedition was to sample rocks from these seamounts to test this geologic origin hypothesis.
