As wer gets deeper there is less oxygen and it gets colder.
Pressure increases
Its intensity decreases.

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.
The temperature goes down ie it gets colder.
Yes, it does. The more you advance towards the bottom of the ocean, the more the water pressure increases. Which is why you implode before reaching the bottom.
As wer gets deeper there is less oxygen and it gets colder.
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
Yes, pressure does increase as your depth increases in the water
Water pressure increases as depth increases.
As magnification increases, the depth of focus decreases.
As the magnification increases, the depth of field decreases.
Depth and temperature affect pressure by increasing the pressure as the depth increases. As depth increases, temperature often falls.
