Visualizations Useful for Teaching Tides
Initial Publication Date: March 19, 2009
Compiled by Jeff Crabaugh at Carleton College (SERC) and the University of Wyoming
Photos, simple animations, animated maps (with video introduction), and field videos that can be integrated into lectures or classes on tides, their distribution in space and time, their role in sedimentary processes, and their use as an energy source.

What are Tides and What Causes Them?
Tides and Water Levels (more info) Animations, photos and illustrations are used to explain: 1) the relationship between the earth, moon and sun in the generation of tides; 2) frequency of tides; 3) tidal variations; and 4) types and causes of tidal cycles. Particularly useful in a class introducing tides for the first time.
Distribution of Tides in Space and Time:
Long Island Sound and Connecticut River Ocean Tide Simulation (more info) Two animated simulations showing color-coded water depths, as well as the location of high and low tides, across the sound and the river during specific phases of the moon. In a video-taped introduction, the utility of these animated maps is explained by Wesleyan University geologist Susan O'Connell.Sedimentation and Geomorphology in a Mega-Tidal Setting: Bay of Fundy, Canada:
Sediment Transport Movies ( This site may be offline. ) Ebbing of the Tide Video- Bay of Fundy: A 22 second time-lapse video of 45 minutes of ebb tide. The tide is seen to recede eventually exposing the large dune bedforms on the floor of the bay. The Bay of Fundy has the highest tides in the world (over 15 meters).

This resource was filmed in 1968 by Canadian sedimentologist Gerard Middleton, McMaster University, and is archived and made available at the personal website of sedimentary geologist Paul Heller, University of Wyoming.


Generating Electricity from Tides:
Tidal Power This resource uses illustrations, photos, and supporting text to explain how electricity is derived from the flux of tides through human-engineered systems involving turbines or tidal 'fences'.
