Although water can’t be compressed there’s a few other factors.
Density changes with temperature, and it’s a lot colder at the bottom then the top.
There are air bubbles in the water, all of it. Although atmospheric air mixing by waves is unlikely to make it all the way to the bottom, biology produces gases via several different methods and gas can be compressed, which reduces the space between water molecules and increases the density.
Yes. Some things I haven’t seen mentioned yet:
