The normal ice cover of that base period may differ significantly cover from ice in future decades ( A and , 1991 ). and it is quite likely this base period ice cover has differed from the normal Great Lakes ice cover of earlier decades of this century ( Assel, 1990 ). Therefore one must be careful not to make generalizations from this tutorial about Great Lakes ice cover for other de-cades or even for specific winters and locations In the Great Lakes for the decades of the base period. The references and bibliographic citations are a good place to start for those readers interested in obtain-ing additional information on Great Lakes ice cover. 6. REFERENCES AND BIBLIOGRAPHY ASSEL.
