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.
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
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.
As air becomes cooler, it becomes more dense. As the air become more dense (heavy), it causes the barometer to rise.
it is more dense in winter
the answer to this question is a density current forms when more dense seawater sinks beneath less dense seawater
the answer to this question is a density current forms when more dense seawater sinks beneath 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.
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.
Seawater is more dense than air. That is why the air rests on top of the seawater and not the other way around.
the lower the temperature gets the more dense the air becomes.
