Among the world's largest oceans, the abyssal zones are the most mysterious. Sunlight does not reach here, and strange biodiversity is observed in the deep sea's pelagic layers. The Pacific Ocean is the largest and contains countless archipelagos, which are unique examples of natural beauty.
The bathymetry analysis of these oceans shows that the salinity and thermocline layers in deep waters are highly variable. Tectonic plate movements create subduction, which results in earthquakes and volcanic eruptions.
The upwelling and gyre currents of the ocean help maintain maritime biodiversity. However, anthropogenic effects such as pollution and eutrophication are causing severe damage to this environment.
The largest oceans are not just water bodies, but are essential for our weather, maritime transport, and biodiversity. Therefore, their conservation is our responsibility.
