The "Seiche" Newsletter

A seiche (pronounced "saysh") is a series of rhythmic rocking motions triggered in a water body disturbed in some way. Seiche-generating disturbances include earthquakes, landslides, wave interactions, and changes of wind or air pressure. The pendulum-like movements within seiches are known to scientists as free standing-wave oscillations. They can continue for hours after the forces that created them have vanished. Seiches can create a range of water-level changes, from imperceptible to those that damage vessels or threaten lives.

The purpose of the Seiche newsletter is to provide a periodic flow of information about Lake Superior and Minnesota's inland waters. The Seiche is published by Minnesota Sea Grant, University of Minnesota Duluth, 31 W. College St., Duluth, MN, 55812.

Circulation is 4,000. For a free subscription, click on the "Subscribe" button on the Seiche web page.
