The vast majority of life on Earth exists in a space that remains almost entirely hidden from human sight.
This is neither the ocean surface nor the sea floor, but the midwater—the massive expanse of water between them, which serves as the planet's largest yet least explored ecosystem.
This is precisely where new technologies are being directed today.
During the Designing the Future 3 expedition, the Schmidt Ocean Institute team is deploying the DeepPIV (Deep Particle Image Velocimetry) system aboard the ROV SuBastian, a cutting-edge imaging tool developed by Dr. Kakani Katija and her Bioinspiration Lab team at MBARI.
Using laser imaging, this technology makes it possible to see exactly how water flows around marine organisms. For scientists, this provides an opportunity to study not only the physical form of deep-sea creatures but also their environmental interactions: how they move, feed, and utilize water currents.
The method is particularly valuable because it is non-invasive, allowing for observation directly in a natural habitat without the need to bring fragile specimens to the surface.
It is a significant step toward exploring the midwater, an oceanic realm that remains one of the largest blank spots on the map of life on Earth.
As the Schmidt Ocean Institute notes, such technologies provide a new lens through which to observe creatures that humanity has long been unable to study in their own environment.
This achievement represents more than just a technical breakthrough.
It signifies a shift in the entire approach: moving from extracting life from its environment toward observing it with respect for its natural state.
The more accurately science learns to see the ocean, the deeper our understanding becomes of how complex, dynamic, and interconnected life is within its depths.
What does this development add to the greater narrative of our planet?
Perhaps it is one more step toward not just researching the ocean, but learning to see its life exactly as it is.
