Through global-scale seismic imaging of the Earth’s interior, research led by the University of Alabama revealed a layer between Earth’s core and mantle that is likely a thin, dense, sunken ocean floor, but… how? Is it possible that there is an ocean under the surface of the Earth? What temperature have? Could there be living things in it?

Ultra Low-Speed Zones (ULVZ)
To better understand this discovery, we must delve into the central topic of the investigation, the Ultra Low-Speed Zones, also called (ULVZ) by their initials.
ULVZs are mysterious and fascinating areas under the Earth’s crust that have puzzled scientists for decades.

The South Atlantic Magnetic Anomaly ( AMAS )
It is a geophysical phenomenon that has puzzled scientists for ages. Refers to a region of the South Atlantic Ocean where the Earth’s magnetic field is significantly weaker than expected based on geographic location. This region stretches from South America to Africa and has been the subject of intense research and debate among scientists.

Buried mountains and oceans
Recently the project led by Research Fellow Samantha E. Hansen of the Department of Geological Sciences, The University of Alabama, conducted seismic wave surveys in the southern hemisphere and Antarctica.
