First-Ever Exploration of Undersea Ridge
Scientists from the MBNMS and Monterey Bay Aquarium Research Institute explored Sur Ridge for the first time last year, confirming the ridge was biologically significant. Offshore Big Sur, the base of Sur Ridge lies 4,400 feet below sea level. The ridge rises 1,300 feet above the seafloor and is about the size of Manhattan. Scientists explored the ridge using a remotely operated vehicle. The team expected to see spectacular corals at the ridge’s top, but was surprised also to find corals extending to its base. Additionally, researchers identified an abundance of sponges and a chemosynthetic community of clams. The ridge has been declared a Sanctuary Ecologically Significant Area and will be the focus of future studies.
