Causes of Tides

Ship drivers have to use their knowledge of tides to safely navigate large vessels under a bridge. Now, you can simulate this experience in the "Be the Captain" application on the National Oceanic and Atmospheric Administration’s website. Follow the instructions provided to adjust the conditions that would allow for low tide and, therefore, enough room for your vessel to travel under the bridge.  If you get stuck, that is okay. You will learn more about the influences on tides and how to predict them later in this topic.
