Magnetic anomalies and the pattern of seismicity suggest that the present Chile Rise has been spreading at 2.7 cm/yr along a NNE axis. Older oceanic crust (25–55 m.y. BP) near the coast of Chile ...

This extended lifespan has enabled Swarm to observe long-term patterns and anomalies that might ... have detected variations ...

They realized that the pattern of reversals matched perfectly the magnetic profile they had compiled of the sea floor. This discovery, together with data from a 1964 research vessel, transformed ...

Magnetite, the most magnetic mineral on Earth, is increasingly being found in seafloor environments that are rich in iron and have high methane flux. But how it forms in such settings—whether by ...
