Does Marine Layer dissipate if the caster falls unconscious or does it stick around for the full duration regardless of the caster's condition?

....Oh no.
I'm not sure either. O_O

I tried looking it up as well, and I haven't found anything on the internet that says whether or not it does. I don't even remember if Fjord from Critical Role (the character who got this Paladin subclass), fell unconscious with this Channel Divinity up.

Sorry rush, I think this is a DM call.
