# Birth of the Ocean: Scientists Record the Formation of New Crust in Real Time for the First Time

Geophysicists have made a breakthrough in understanding the evolution of our planet, recording the birth of new oceanic crust directly for the first time in history. Observations allowed them to see how magma rises from the Earth's interior, solidifies under the pressure of ocean water, and forms new sea floor.

### Observing the Earth's Interior

The scientific discovery was made possible thanks to the work of a group of French researchers. Scientists used an autonomous observatory installed near Amsterdam Island in the Indian Ocean. This region is notable for its location near the Southeast Indian Ridge — a zone where the Australian and Antarctic tectonic plates meet.

To monitor what was happening on the ocean floor, five hydrophones were deployed. The equipment recorded seismic and geophysical fluctuations, allowing scientists to construct an accurate picture of the events.

### Evidence of Tectonic Shift

Analysis of the obtained data revealed a series of underwater earthquakes. Immediately after these events, the ocean floor in the ridge area subsided by 4.2 meters. The entire subsidence process took several days.

According to the researchers' conclusions, the cause of such significant displacement of the floor was the emptying of a giant magma reservoir located 3.6 kilometers deep beneath the Earth's crust. The magma left the reservoir, rose to the surface, and cooled, creating a new layer of rock.

### Significance of the Discovery for Science

Although the concept of seafloor spreading has long been known to science, confirmation existed only in the form of indirect evidence: age layers of the crust and striped magnetic anomalies. Recording this process directly at the moment it occurred was achieved for the first time.

"About two-thirds of the Earth's surface was formed precisely on mid-ocean ridges during such eruptions," emphasize the scientists, pointing to the global significance of the observed phenomenon.

### Limitations and Prospects

Despite the historical importance of the discovery, independent geophysicists note certain limitations of the conducted study. Seismic measurements allowed determining the epicenters of the earthquakes, however, the exact depth of the foci remained undetermined.

Furthermore, topographic measurements of the floor conducted before and after the event had limited resolution. This leaves some uncertainty regarding the exact scale of the floor deformation, but does not negate the fact of the successful recording of the birth of new crust.
