Water cools as it moves to higher latitude making dense (high salt, low T) water off coast of Greenland that sinks. If Greenland ice sheet melts rapidly the water becomes less saline and less dense. This will retard NADW formation. 11) The magnetic striping is due to the mid-ocean ridges continually making new basaltic rock on the ocean floor. As the magma from the ride cools it takes on the orientation of the Earth’s magnetic field and then solidifies.
