  • Corals in the Juan de Fuca Canyon and the Davidson Seamount

    Discover some amazing corals in this footage that shows and identifies a range of deep-sea coral species from the Juan de Fuca Canyon off the Olympic coast and the Davidson Seamount, an underwater volcano outside the boundary of the Monterey Bay National Marine Sanctuary in the Pacific Ocean. Explore more in the multimedia feature "Coral Gardens of the Deep Sea."

    Understanding the Japan Earthquake and Tsunami

    Using maps and graphics, Smithsonian geologist Dr. Liz Cottrell provides an overview of the major earthquake and tsunami that struck Japan on March 11, 2011—one of the largest ever recorded globally. She explains the Pacific “Ring of Fire,” the movement of tectonic plates and subduction, the concept of earthquake magnitude, and the formation of tsunamis. Dr. Cottrell is also director of the Global Volcanism Program at the Smithsonian’s National Museum of Natural History.

  • Submarine Volcanoes and Hydrothermal Vents

    Recent scientific discoveries have revealed an underwater community of marine animals and other organisms that thrive in the dark depths of the ocean near hydrothermal vents and undersea volcanoes. This ocean ecosystem is dependent on the presence of hydrothermal vents, which release hot and mineral-rich fluids from the seafloor.

  • Submarine Volcanoes Erupting

    Did you know that 80 percent of the volcanic eruptions on Earth take place underwater? These underwater eruptions occur regularly, forming new landmasses and providing a living environment for deep-sea creatures. In 2009, scientists discovered the deepest ocean eruption ever found—the West Mata Volcano. Explore other videos that capture the beauty and mystery of the ocean realm at NOAA Ocean Today.

  • Giant tortoise habitat on Galapagos Islands.

    Cerro Azul, Isabela Island, Galapagos Islands

    A giant tortoise subspecies (Geochelone nigra vicina) lives on Isabela Island in the Galapagos. Cerro Azul, estimated to be about 350,000 years old, is one of six volcanoes on the island.

    Protecting Fragile Species

    Sarah Gotheil, from IUCN Global Marine Programme, snapped this photo in the course of her research into fragile species and ecosystems. A new project led by IUCN will unveil the mysteries of southern Indian Ocean seamounts and help improve conservation and management of resources. Two research expeditions will survey seamounts, underwater mountains of volcanic origin that are hotspots of marine biodiversity. For more about this project, visit the IUCN website.

  • A remotely operated vehicle (ROV) recovers a volcano monitor from an underwater observatory.

    ROV Recovers Volcano Monitor

    The remotely operated vehicle ROPOS recovers a volcano monitor from NOAA’s New Millennium Observatory on the Juan de Fuca Ridge, off the coast of the Northwest United States. The station was set up to study geological, chemical, and biological interactions along the mid-ocean ridge system. ROPOS can now be seen in Sant Ocean Hall.

  • The New England Seamount Chain is the longest in the North Atlantic Ocean and includes peaks of more than 30 extinct volcanoes.

    Map of New England Seamount Chain

    The New England Seamount Chain is the longest in the North Atlantic Ocean. It includes more than 30 major volcanic peaks. Seamounts provide a solid surface for corals and other marine animals to cling to.

  • Where There’s Smoke…

    Students explain how fundamental relationships between melting and boiling points, solubility, temperature and pressure can help to develop plausible explanations for observed chemical phenomena in the vicinity of subduction volcanoes.

  • What Was for Dinner

    Students will be able to compare and contrast photosynthesis and chemosynthesis as sources of primary production for biological communities; give at least three examples of organisms that live near hydrothermal vent systems; and describe two sources of primary production observed in biological communities associated with volcanoes of the Marianas Arc.
