it would sink
There are a number of things that could happen to the salinity of an ocean if it's depth increased. The salinity would likely also increase.
They would most likely drown, freeze, get eaten by sharks or die of starvation/dehydration
If plate tectonics did not happen, the ocean floor would likely be smoother and more uniform, without the presence of mid-ocean ridges, trenches, and seismic activity caused by plate movements. Mountain ranges and underwater volcanoes associated with tectonic activity would also be absent.
there would be no ocean anymore.
