Seeing Sur Ridge: Transforming deep-sea mapping data to reveal the majesty of an underwater oasis

In 2013, after many years spent mapping Monterey Bay and its environs, MBARI and MBNMS scientists discovered an underwater oasis—lush with corals and sponges—just 35 kilometers (22 miles) west of Big Sur. This rocky ridge, called Sur Ridge, stands over 500 meters (1640 feet) tall and stretches over 20 kilometers (12 miles) long—roughly the size of Manhattan. MBARI has been working diligently to create ever more detailed maps of Sur Ridge for more than twenty years to better understand its geologic processes—like underwater landslides—and to monitor the health of the marine life that calls it home—including the impacts of climate change.

Data collected by MBARI’s mapping team has helped bring Sur Ridge to life. This animation combines data from ship-based multibeam sonar at 25 meters (82 feet) in resolution, autonomous underwater vehicle (AUV) multibeam mapping data at one meter (about three feet) in resolution, and remotely operated vehicle (ROV) mapping lidar data at five centimeters (two inches) in resolution. MBARI scientists worked with Los Angeles film production company Frame 48 to visualize the terrain of Sur Ridge in astonishing detail. These amazing images demonstrate what’s possible when scientists and engineers work together to develop new technology for exploring the deep ocean.
