For WHOI personnel and vendors: COVID-19 Guidelines

How Does an Observatory Work?

When magma rises through Earth’s crust to a mid-ocean ridge, ocean observatory sensors detect the ground motion, the spilling lava, and the chemicals spewing from hydrothermal vents. Observations are relayed back to shore-based researchers, who can command their instruments and a robotic vehicle to make specialized measurements, and then muster an expedition to inspect the eruption firsthand.
