Contrary to previous general beliefs, the Deep Scattering Layers DSL of the Mediterranean appear weak but well developed, and comparable to the DSL of the Atlantic and the Pacific. The midday depth of the upper edge of the DSL appears to be between 280 and 310 m, which is about 60 m deeper than the one found in the Eastern North Atlantic. This layer can be as thick as 100 m and is often divided. A second layer is frequently recorded below 380-420 m. These depths appear to be 35-50 m deeper in the southeastern Mediterranean than in the northwestern difference in latitude about 7 degrees. The sunset and sunrise migrations show up to three groups migrating vertically in sequence and at different rates. Author
