The Benthic Nepheloid Layer (BNL) is the the thickest and upper of three layers into which the bottom 1000 m of the ocean are sometimes divided, with the other two being the Bottom Mixed Layer (BML) and Bottom Ekman Layer (BEL).

This article is written at a definitional level only. Authors wishing to expand this entry are inivited to expand the present treatment, which additions will be peer reviewed prior to publication of any expansion.
The BNL is characterized by an increasing concentration of suspended material towards the bottom, and it extends from the clear water minimum (CWM) (at around 1000 meters above the bottom) down to the deep–sea bottom.
