I don't care what Google says. I know what physics says.Not according to google. According to google it’s 200 meters and drops off greatly within a couple of meters.
But so what? Why is there a thermal gradient below that? Where is that heat coming from? Because it gets colder the deeper it gets. Are you saying heat is rising from colder waters to warmer waters? That’s idiotic.
Physics trumps computer derived fiction.
Every. Single. Time.
