... of these seamounts were surveyed by echo sounder, dredged, and cored, and were found to be peaks on a great submarine range—the Mid-Pacific Mountains—which extends from Necker Island in the Hawaiian Islands to near Wake Island. The flat-topped guyots are submerged to between 700 and 900 fathoms. The sides...

..., changes in sea-water oxygenation, acidity, or temperature should be expected to shift species depth ranges on ocean seamounts, guyots, and submarine mountain chains ( Ramirez-Llodra et al., 2011 ). Benthic faunas on seamounts show high endemism (e.g., McClain, 2007 ) and, like isolated terrestrial...

However, core-based sedimentologic studies of modern sediments emplaced by baroclinic currents on continental slopes, in submarine canyons, and on submarine guyots are lacking. No cogent sedimentologic or seismic criteria exist for distinguishing ancient counterparts. Outcrop...

... bioproduction. Mercury contents reach 148 ppb in hydrogenic ferromanganese crusts on flat-topped seamounts. Such crusts, with up to 4120 ppb Hg, were dredged from the slopes of Seth Guyot in the western Marcus-Wake Seamounts in 1982, during the 13th cruise of RV Vulkanolog. The Seth Fe–Mn crusts are of the same...
