Ocean (deep water zone)

"The lower portion that is far from the surface of the ocean. It is below the mixed zone. Layers of water form in the deep ocean due to differences in water temperature and salinity (and therefore water density). Ocean (deep water zone) is a water cycle pool." (U.S. Geological Survey, 2022)
