May 2013 What is a TIDE Rise and fall in ocean levels Most observable at the coastlines What is a TIDE 2 High tides and 2 Low tides occur daily Approx 6 12 hours apart What causes TIDES. They follow a cycle that coincides with the 24 hour 50 minute lunar day the time it takes earth to make one complete rotation relative to the moon Along Americas Atlantic Coast two high and low tides occur daily with relatively little difference bet Waves.

Doodson. & Warburg, 1941, His Majesty’s Stationery Office. Orbital Force Balance. Tides are forced by the sun and moon, with similar physics. The Moon’s forcing is about twice that of the sun.. Description of Waves. A wave is the rhythmic movement that carries energy through space or . matter. Waves are generated by wind flowing over the water . surface. As a wave passes, water moves up and down in a circular pattern – returning to its original position. Overview. What is a Tide?. Types of Tides – Spring and Neap. High and Low Tides.

Get your oceanography toolbox out. Let’s try to fill in the parts. Oceanography Toolbox. Van Dorn Bottle. Used to capture water samples at different distances. Created by Winds. Coriolis Effect- The shifting of ocean currents and surface winds from their expected paths caused by the rotation of the earth. Gulf Steam – ocean current in the northern Atlantic ocean, brings warm water from Africa to the Americas. What are tides?. Tides are the daily changes in the level of ocean water..
