Seawater becomes more dense when the temperature decreases or when salinity increases. Cold water is denser than warm water, and water with higher salt content is denser than water with lower salt content.
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.
The troposphere is typically more dense in the winter due to colder temperatures causing air to contract and become denser. In the summer, warmer temperatures cause the air to expand and become less dense.
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
Seawater denssity will increase as salinity increases. A less significant increase can result from temperature variations (colder is denser until freezing starts). Even smaller changes would occur with depth as the seawater is slightly compressible. As density is measured as mass/unit volume local gravity does not enter into the process.
Convection currents in the mantle are caused by the heat generated from the decay of radioactive isotopes in the Earth's interior. This heat causes the mantle material to become less dense and rise, then cool and become more dense, leading to a continuous cycle of heat transfer and movement in the mantle.

A density current forms when more dense seawater moves toward less dense seawater.
A density current forms when more dense seawater moves toward less dense seawater.
A density current forms when more dense seawater moves toward less dense seawater.
I would be thinking the salt is the reason. The salt makes the water more dense, so things that were more dense as compared to the water before become less dense as compared to seawater. So yeah, that's why things are more buoyant in seawater.

Density current
density current
Density currents - more dense seawater sinking beneath less dense seawater.
the lower the temperature gets the more dense the air becomes.
