1. The image below shows measurements obtained from a deep ocean (550m)

1. The image below shows measurements obtained from a deep ocean (550m) array of temperature sensors arranged vertically above the seafloor. The image shows changes in temperature versus time as a current flowed past the sensors. In the image, the thickness of the layer between the red and the blue regions (~ 7m) is determined by the potential energy vs kinetic energy balance (i.e. Ri = 0.25). If we approximate the flow as two layers with T = 13.3 degC and T2 = 12.8 degC, calculate the corresponding change in velocity (shear) between the two layers. How large would the shear need to be for the intermediate layer to reach the sea bed? 25 T (C) z(m)-549m 25 20 20 13.3 13.2 13.1 15 13 10 12.9 12.8 5 20:45:00 20:50:00 20:55:00 21:00:00 21:05:00 time (hh:mm:ss)
