Reply to comment by crazunggoy47 in How fast do bubbles rise in water? by crazunggoy47

If you release the bubbles in the deepest parts of ocean, below 8000 m, the bubbles would have so high density that they will sink instead of rise.

This because the air compressed to more than the pressure at that depth will have a density higher than water.

But probably will the bubbles dissolve rather quick, but a baloon will definitely sink. You could fill the Marianer trench with air! Maybe.

Wow, I plugged in a pressure of 16000 PSI into this calculator and you're right! It exceeds the density of water. That's weird.

So is there a depth line where bubbles would become buoyant?

It looks like it. See my comment to TexasPop. Air matches the density of water at a water depth of around 5.3 miles.
