In honor of Earth Day, we invite you to relax with these stunning scenes miles below the ocean’s surface. The landscape of the deep sea is everchanging, with views that rival the sublime beauty found at our national parks and monuments on land. Canyons have sediment tumbling down their steep walls, tectonic plates move against each other, causing underwater earthquakes, and volcanoes erupt with flowing lava. The most prolific volcanic systems on Earth are hidden beneath the ocean’s depths. Scientists have estimated that there could be more than one million submarine volcanoes around the world. Volcanic eruptions result in a remarkable variety of formations as molten lava hardens at various speeds in cold seawater to form spectacular features like bulbous pillows, hollow domes and channels, jagged pillars, and folding sheets.

Although the entire ocean crust was created this way, it is exciting and rare—even for deepsea geologists—to observe this breathtaking scenery. Less than ten percent of the seafloor has been mapped at the same level of detail as the Moon and Mars. MBARI’s mission is to advance marine science and technology to understand our changing ocean—from the surface to the seafloor. For more than three decades, we’ve explored the deep ocean, recording thousands of hours of video with our remotely operated vehicles and mapping thousands of kilometers of seafloor using advanced mapping vehicles. Together, these tools are helping to create a clearer picture of the uncharted ocean frontier.
