And then, the team noticed a solitary periwinkle deep-sea octopus along a rocky outcrop, and then another. This was a whale fall, where several deep-sea octopuses and other creatures were busy feasting upon the remains of a whale on the seabed. Each year that scientists embark on another expedition, cataloguing species and documenting the life of this seamount, is so important to the exploration off the California coast. At the seamount’s base, strong currents produce localized upwelling, sending nutrient-rich water from the deep to the sunlit waters above. It was a smart call. This underwater goliath lies 75 miles west of San Simeon, Ragged Point and Gorda, stretching 26 miles long and 8 miles wide. Soon, the ROV glided across a cluster of about 25 brooding female octopuses. We know they’re all around that summit area, and we want to go back.”, Deep-sea expeditions such as this uncover new discoveries, such as this octopus garden. We observed over a thousand deep sea octopus (Muusoctopus robustus) while exploring Davidson Seamount with Monterey Bay National Marine Sanctuary. It is one of the largest known seamounts in U.S. waters, with a peak of 7,500 feet above the seafloor, and is the only seamount protected within the National Marine Sanctuary System. Images from this cruise are making their way to Web sites, and have already been exchanged with scientists on-shore to begin the description of what is probably a new species of branching sponge. Out of time, they began their journey back up to the surface. The images from the 2002 Davidson Seamount expedition excited the public and motivated protection of deep-sea corals and seamounts. The team was exploring the Southeast Davidson Seamount off the coast of California with Explorer Vessel Nautilus when they came across the incredible gathering of Muusoctopus robustus octopuses.

NOAA's national marine sanctuary offices and visitor centers are closed to the public while the waters remain open for responsible use in accordance with CDC guidance and local regulations. Huddled close to rocks, many of the females were seen in an “inside-out” body position, which indicated that they were brooding. The octopus garden was discovered at the cold, dark depth of 12,000 feet in a rocky area at the base of Davidson seamount. Map of MBNMS with Davidson Seamount in the front. “It was just like euphoria set in the control room,” King describes. The boundary change adds a 775 square mile area to the MBNMS, increasing the MBNMS area to 6,094 square miles. Only 45 minutes remained in the dive, and after referring to a bathymetric map, King made the decision to venture to the seamount’s steeper side, to the east. The Davidson Seamount has often been called an Oasis of the Deep, filled with fragile deep sea corals below and teeming above with marine life such as whales, seabirds, sea turtles, tuna, sharks, and swordfish. New technology has only recently allowed scientists to bring back dramatic high resolution images from the deep sea, offering researchers and the public an opportunity to witness the never before seen glimpses of rare marine species living in this largely cold, dark, and mysterious habitat. It has been called "An Oasis in the Deep," hosting large coral forests, vast sponge fields, crabs, deep-sea fishes, shrimp, basket stars, and high numbers of rare and unidentified benthic species. If you’ve done several ROV dives there, you’ve still barely seen anything.”, King says that diving with an ROV on Davidson Seamount is “like being dropped in a national park with a couple of powerful flashlights. Cameras from ROVs Hercules and Argus captured the population dynamics at play.
