The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included. Places where seawater and rainwater is pumped away are included.
The mesopelagic zone is important for water mass formation, such as mode water. Mode water is a water mass that is typically defined by its vertically mixed properties. [5] It often forms as deep mixed layers at the depth of the thermocline. [5] The mode water in the mesopelagic has residency times on decadal or century scales. [5]
The Ocean is presented first of all as the greatest world river (Hom. Il. XIV 245), [3] surrounding the Earth and the sky with the seas, [13] giving rise to all rivers, springs, sea currents and seas in the world (XXI 196), the shelter of the Sun, Moon, stars and planets, from which they all rise from the ocean and set in it (VII 422; VIII 485).
The region in the water column at which calcite dissolution begins to occur rapidly, known as the lysocline, is typically located near the base bathypelagic zone at approximately 3,500 m depth, but varies among ocean basins. [24] The lysocline lies below the saturation depth (the transition to undersaturated conditions with respect to calcium ...

This is due to the fact that surface waters in polar latitudes are nearly as cold as deeper waters. Below the thermocline, water everywhere in the ocean is very cold, ranging from −1 °C to 3 °C. Because this deep and cold layer contains the bulk of ocean water, the average temperature of the world ocean is 3.9 °C. [92]
