    Yeah, it’s been 15 years since I’ve taken oceanography, but the density of water is determined by its temperature.

      Density is certainly changeable in water with temperature, but density isn’t exactly the same thing as compression.

      TIL A waterjet cutter pressurizes the water to something like 90,000 psi and it gets about 14% more dense. I always thought those things just had the water highly pressurised, but not actually compressed.

        I want to posit that because water isn’t compressible at forces we experience commonly, it doesn’t mean it isn’t compressible. For 99.999% of the water rules we concern ourselves with water should be considered incompressible, but there are exceptions to every rule
