  1. Warm-Up 9/23 • What is the difference between an upwelling and a downwelling current? • How does the thermohaline current known as “the global conveyer belt” help to stabilize the global climate? • Why might you observe an abundance of life and biological productivity near upwelling currents? UNIT TEST THIS FRIDAY! TOPICS: Everything covered so far.
