Alien oceans could prevent evidence of deep-sea life

…what? I mean I’ll read it, but the title doesn’t make sense to me.

Edit:

A new study on Enceladus, a moon of Saturn, reveals that the physics of its ocean might prevent evidence of deep-sea life from reaching the surface. Enceladus’s ocean forms layers that significantly slow material movement from the ocean floor to the surface, making it harder to detect signs of life.

So a clearer title would be something like:

Nature/Physics of alien oceans could prevent easy observation of possible life.
