Secret World Discovered Beneath the Ocean Floor
OFF THE COAST OF CENTRAL AMERICA — In an exciting announcement this week, a team of international ocean researchers revealed they have found an entirely new world of living things hidden beneath the ocean floor. For decades, scientists have studied strange animals living around hydrothermal vents, which are volcanic chimneys on the seafloor. However, this is the very first time anyone has discovered animal life thriving underneath those rocky vents inside Earth's crust.
The groundbreaking mission was conducted using SuBastian, an advanced robotic submarine. Operators on the research vessel Falkor (too), operated by the Schmidt Ocean Institute, guided the robot through the dark waters of the Pacific Ocean. The submersible dived nearly 8,000 feet deep, where water pressure is crushing and sunlight never penetrates.
While exploring, SuBastian used its mechanical arm to flip over heavy slabs of volcanic shelf rock. Operators expected to see bare rock beneath, but to their surprise, they uncovered a network of underground cavities and tunnels filled with warm water. Living inside this hidden layer were snails, small worms, and even giant tubeworms measuring several inches long.
- hydrothermal vents:
- Openings in the ocean floor that release mineral-rich water heated by underground volcanic activity.
- submersible:
- A specialized underwater vehicle built to explore deep ocean areas where humans cannot easily go.
- photosynthesis:
- The biological process by which green plants use sunlight to create food and energy.
- chemosynthesis:
- The process by which certain organisms make food using energy released from chemical reactions rather than sunlight.
- ecosystem:
- A biological community of interacting living organisms and their physical environment.
