Scientists at MBARI have developed a new tool called Geo-Sense to study the seafloor. It uses light to measure tiny vibrations and strains on a fiber-optic cable, helping researchers understand processes like earthquakes and landslides.
The seafloor plays a crucial role in our ecosystem and economy. To protect it, scientists need to understand how it changes over time. Since 2025, a team at the Monterey Bay Aquarium Research Institute (MBARI) has been testing Geo-Sense, a new tool that uses light to study the seafloor.
Geo-Sense works by placing a fiber-optic cable on the seafloor and using it to measure tiny vibrations and strains. This helps researchers track processes like earthquakes, landslides, and volcanic activity in real-time. The data collected can be used to make better decisions about underwater infrastructure and conservation policy.
The team at MBARI had to overcome many challenges to develop Geo-Sense. One of the biggest hurdles was deploying and recovering the fiber-optic cable on the seafloor. This required a lot of expertise in marine geology, geophysics, and engineering.
MBARI's Seafloor Processes Team is led by senior scientist Aaron Micallef, a marine geologist. He explained that Geo-Sense is a major step forward for seafloor science because it allows researchers to observe processes in real-time at very fine spatial and temporal scales.
Why It Matters
This technology can help India's coastal communities prepare for natural disasters like tsunamis and landslides, which are becoming more frequent due to climate change. It can also inform conservation efforts and help protect marine ecosystems that provide livelihoods for many Indians.
