Buoyancy

Choose one creature you can see within range. Blue ribbons of magical air coalesce into bubbles that surround the targeted creature. The target must succeed on a Strength saving throw, or its swimming speed (if any) is reduced to 0 feet for the spell’s duration. A creature affected by this spell, and is underwater, safely ascends at 60 feet per round until it reaches the surface of the water or the spell ends.
