Exploring the effect of water on seismic wave attenuation in the upper mantle

The oceanic lithosphere, which constitutes the top layer including Earth’s crust and mantle below the oceans, has long intrigued scientists due to its peculiar behavior. This layer appears to glide over a weaker region below called the asthenosphere, characterized by high seismic attenuation and low shear wave velocity.
