Hint:-Ocean desert is also called dead zones. It refers to the parts of oceans that don't support life. It can be due to various factors like nitrogen excess and draining of sewage from the industries into it. These factors make the oceanic desert unsuitable for living and survival.

Complete step-by-step solution:-
The Sargasso Sea is situated in the region of Atlantic. The sea remains still with seaweeds floating on the surface, the Sargasso Sea is an example of an ecosystem. Biologists often refer to it as a biological desert, because it's largely devoid of plankton,which serve as the basic food supply for small organisms and fishes . The sea boundary is formed by the Gulf Stream, Canary Current, Atlantic Current, which together form a clockwise-circulation of water currents called the North Atlantic Gyre. The Red Sea is located in the Indian Ocean. It is a part of the Great Rift Valley and supports marine life and corals.
The Arabian Sea is located in the northern part of the Indian Ocean. The boundaries of the Arabian Sea are formed by Pakistan, Iran, and India. The Arabian Sea is one of the most important marine trade routes since ancient times. Marginal sea is formed by the sea of japan. The borders of the Sea of Japan are formed by the archipelago, Sakhalin, and the Russian borders. No tides are formed because it’s completely enclosed from the Pacific Ocean. The high biological productivity of the seawater is due to its elevated concentration of dissolved oxygen. Fishing is one of the most dominant economic activities performed in the region.

Note:- It is differentiated from the other parts of the Atlantic Ocean region by the presence of classical brown colored Sargassum. The blue color and water clarity and clear underwater vision make the Sargasso Sea one of the most famous Sea. The sea boundary is formed by the Gulf Stream, Canary Current, Atlantic Current, which together form a clockwise-circulation of water currents called the North Atlantic Gyre.
