Document Summary
An increase in seawater density can be caused by a ________ in temperature or a/an ________ in salinity. decrease; increase. To produce a surface current of 1. 6 knots in the open ocean, a steady wind of _____ knots would be required. Ekman transport is to the right of the wind direction in the northern hemisphere. Ekman transport can result in both upwelling and downwelling. The coriolis effect causes surface waters to move at an angle relative to the wind direction. In the deeper layers of the ekman spiral, water can move in a direction opposite of the wind direction. Surface waters are pushed away from land and replaced by nutrient-rich bottom water through: upwelling. Converging surface waters are areas of ________ and ________ productivity. downwelling; low. Coastal upwelling along the coast of chile is a result of winds from the ________ turning towards the.
