Exploring Davidson Seamount is a crucial next step toward learning how to protect and conserve important places in our ocean and promote healthy ecosystem management. From base to crest, the seamount is 7,480 ft tall, yet its summit is still 4,101 ft below the sea surface. Related Links. Image: NOAA. Seamounts—where underwater volcanoes emerge from the seafloor—are oases of the deep ocean, hotspots for biodiversity both above and below the surface. The boundary change adds a 775 square mile area to the MBNMS, increasing the MBNMS area to 6,094 square miles. At Davidson Seamount, roughly two miles below the surface of the Pacific Ocean, the Exploration Vessel Nautilus discovered the largest deep-sea octopus nursery ever found in our world’s oceans. The answer came in a glimpse of a shimmer. Just a few hundred yards from exploring a new peak, they found more rows of octopuses lined up in the cracks of the cliffs. Davidson Seamount.
