Seiche

Spring 2007



Fall 2007



http://en.wikipedia.org/wiki/Seiche

This is completely normal in the late fall with a strong west wind. Lake Erie is very shallow near the Michigan shore.

Those grand fresh-water seas of ours - Erie, and Ontario, and Huron, and Superior, and Michigan, - possess an ocean-like expansiveness...They contain round archipelagoes of romantic isles...they have heard the fleet thunderings of naval victories...they know what shipwrecks are, for out of sight of land, however inland, they have drowned full many a midnight ship with all its shrieking crew. --from Moby Dick

In addition to seiches, the Great Lakes also have a very small lunar tide. It's basically undetectable because wind waves and swell more than camouflage its presence.

Very cool pictures!

It must be vanishingly small, because I've always heard there was no tidal action (although it seems a bit illogical).

Speaking of seiche, with the winds we've had today, I would expect the west end of Erie to be new farmland and the east end to be a new water park.

The Fall 2007 picture was taken today.
