Answer to Question 1

 Water moves at a 45 angle from the wind direction. It moves to the right in the Northern Hemisphere and left in the Southern Hemisphere. With each deep layer of water, the angle of movement continues in relation to the floe in the layer above it. Each layer, however, moves slower than the layer above it. This is the Ekman spiral.
 The deflection of the current movements is due to the Coriolis Effect. It shifts the direction of the topmost layer. The other layers then move in response to that initial layer.
 At a certain depth in the Ekman spiral the water flows in the opposite direction of the surface current. This is called the friction depth.
 The net movement of water directions in the Ekman spiral is called the Ekman transport. This should travel approximately 90 angle of the wind direction, but it barely reaches a 45 deflection angle. This is the result of interactions between the Coriolis Effect and the pressure gradient.
