A microlecture (video) that introduces the topic of upwelling in oceans and how the direction of motion of water in the oceans is influenced by the Coriolis Effect.

Students will learn how the Coriolis Effect on the Trade Winds at the equator influences the movement of surface water in the oceans causing an upwelling of colder water from the bottom of oceans. This affects equatorial temperatures and the growth of phytoplankton and fish populations while impacting large scale climatic conditions like El Niño.

Use this tool to help your students find answers to:

  1. What is upwelling? How does the Coriolis Effect affect upwelling in the oceans?
  2. What is the impact of ocean upwelling on climate?
