The layer is deeper when the moon is out, and may move higher when the sky is dark. This phenomenon has come to be known as the deep scattering layer. Most...

false bottom can also refer to the deep scattering layer in the ocean, a phenomenon where a layer of marine organisms deep in the ocean can be mistaken by...
