Pescadero Basin: Matterhorn Vent Tube Worms- 2017 (Remastered!)

Travel with us back to 2017, when we explored the deepest high-temperature hydrothermal vents in the Pacific Ocean in the Gulf of California’s Pescadero Basin. True to its name, the Matterhorn vent site towers above the seafloor, topped with a coppery crop of Oasisia tube worms. This dense chemosynthetic community was one of several we surveyed during the week-long expedition with research partners at Woods Hole Oceanographic Institution and the Dalio Explore Fund.  

High-temperature hydrothermal vents at mid-ocean ridges typically produce chimneys dominated by sulfide minerals. In contrast, the Pescadero Basin vents host delicate structures composed of light-colored carbonate minerals. The Pescadero Basin vents also host deep-sea biological communities thriving among carbonate chimney structures, including communities dominated by tubeworms.
