The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. [2]
This is a list of seas of the World Ocean, including marginal seas, areas of water, various gulfs, bights, bays, and straits. [2] In many cases it is a matter of tradition for a body of water to be named a sea or a bay, etc., therefore all these types are listed here.
Shallow water marine environment refers to the area between the shore and deeper water, [clarification needed] such as a reef wall or a shelf break. [ clarification needed ] This environment is characterized by oceanic, geological and biological conditions, as described below.
The Sea of Azov is an internal sea with passage to the Atlantic Ocean going through the Black, Marmara, Aegean and Mediterranean seas. It is connected to the Black Sea by the Strait of Kerch, which at its narrowest has a width of 4 kilometres (2.5 mi) and a maximum depth of 15 metres (49 ft). [ 1 ]

Detail from NOAA nautical chart 12300 showing the Nantucket Shoals in relation to Nantucket Island.. Nantucket Shoals is an area of dangerously shallow water in the Atlantic Ocean that extends from Nantucket Island, Massachusetts, eastward for 23 miles (37 km) and southeastward for 40 miles (64 km); in places water depth can be as shallow as 3 feet (0.91 m).

When the ocean is relatively calm and shallow, there is also less plankton, sand, particles, and other materials constantly churning in the waves, which gives the water a clearer appearance ...
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately 200 meters (660 ft) in depth.
