# Question regarding high air pressure on water in a closed cylinder

I am working on a project concerning aquaculture and the elimination of living (live) invasive species being transferred from one location to another.

My question is:

Suppose you have a air tight cylinder/tank/vessel that is half full of water. With one pressure gauge above the water line, and another pressure gauge at the bottom of the vessel.

If you then add 100 psi of compressed air to the top of the cylinder,... ... does the pressure in the water also read an additional 100 psi ?

thank you in advance for any replies
