In the case of gases yes. For a gas, the density is directly proportional to the pressure and inversely proportional to the temperature (absolute ie Kelvin). In other words the higher the temperature the lower the density. This is because gases expand with temperature. Liquids and solids do expand but only slightly so there is not much change in density for these.
The most important factor affecting seawater density is its temperature. As temperature increases, seawater density decreases, causing it to expand and rise. Conversely, as temperature decreases, seawater density increases, causing it to contract and sink.

It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density.
