Pescadero Basin: Matterhorn Vent Tube Worms
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 Pescadero Basin Expedition in the Gulf of California with research partners at Woods Hole Oceanographic Institution and the Dalio Explore Fund.

Pescadero Basin
In 2015, the deepest high-temperature hydrothermal vents in the Pacific Ocean were discovered in the Pescadero Basin of the Gulf of California. Initial observations revealed enigmatic aspects of this vent system, including unique mineralogical composition and fluid geochemistry, suggesting that there is much to be learned about deep ocean carbon dynamics in this system.
