The sea is not a substance in the traditional sense; rather, it is a large body of saltwater that contains various substances, including dissolved salts, minerals, and organic matter. It is composed of water, which is a chemical substance (H2O), but the sea itself is an ecosystem and environment rather than a singular substance. Additionally, the sea interacts with the atmosphere, land, and living organisms, making it a dynamic system rather than a static entity.
It is a mixture. A pure substance contains only one type of substance or one species of any substance or element. Sea water is a mixture of different salts dissolved in water. Thus, it is not a pure substance. Another point is that the different components of sea water can be observed separately.

It is a mixture of water, salts and oxygen.
A substance that contains a sea of electrons is typically a metal. In metals, the outer electrons are free to move throughout the material, creating a "sea" of delocalized electrons that allows for good electrical conductivity.
