The abyssal zone, or the abyss, is the seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth, where sunlight doesn’t penetrate.
Abyssal Zone Woods Hole Oceanographic Institution is the world's leading non-profit oceanographic research organization. Our mission is to explore and understand the ocean and to educate scientists, students, decision-makers, and the public.
The ocean water column is made up of five zones: the sunlight (epipelagic), twilight (mesopelagic), midnight (bathypelagic), abyssal (abyssopelagic) and hadal zones (trenches).
- Introduction The rate of diapycnal mixing relates through the buoyancy equa-tion (McDougall, 1991) and vorticity dynamics (Stommel and Aarons, 1960) to the intensity of upwelling and horizontal circula-tionintheabyssalocean.Similarly,theintensityofdiapycnalmixing relates to the ability of the abyssal ocean to store heat and carbon. Mixing associated with internal wave breaking is an ...

- Introduction The distribution and intensity of diapycnal mixing and vertical velocities in the deep oceans are funda- mentally related to the abyssal flow dynamics and strat- ification. Stommel (1958) was the first to propose a dynamical connection between the abyssal circulation and bottom water formation and modification processes. In his model, cold water sinks in confined, isolated ...
