As I understand, water pressure increases as we go towards bottom of the ocean. So if an object* is thrown into water and it starts sinking with some speed, does the sinking object's acceleration increase with increasing pressure?
Also does water solidify under very high pressure and if so is that high pressure achieved at the ocean bottom? If so, would a sinking object stop sinking and rest on the "solidified" water, if we have a deep enough ocean?
- e.g. black box of a submerged plane

That is right, deeper the pressure is stronger. But the pressure is not just in one direction it is in every direction. So the velocity will decrease in most cases. But also you have to be aware of the density of the object. You could read this classical description of diving objects "Thrust" on wikipedia. This is a classical effect, in real cases the relation between deepness and pressure is not always linear.
Here is an example of the every direction pressure.
And answering the other question. That is possible under some specific conditions. You could have solid water. But I don't know exactly if our planet is capable of have that rare condition. In addition I have found information of a exoplanet that matches those conditions NatGeo.
