Answer:

I think its true because the sea water density varies with salinity, temperature, and depth.

Yes, it is true that ocean water density varies more at poles throughout the year than at the equator.

What is ocean water density?

Therefore, increasing salinity would lead to an increase in the density of ocean water.
