This term is used regularly in the European literature but I am unable to find a clear definition (in English). The derivation of the word would suggest "slow mixing" but what exactly is ocurring slowly? Some descriptions of bradymictic lakes mention a long period of ice cover, so is it "delayed mixing"? Other descriptions suggest bradymictic is almost meromictic, a very short period of mixing and perhaps incomplete reoxygenation of the hypolimnion. If North American limnologists don't use bradymictic, what would they use instead to describe such lakes?
The term bradymicitic is used by Polish limnologists, only. The original citation might be in one of the 3 papers given below (in Polish and German).
See Skowron 2009: "Passowicz supplements this taxonomy in 1938 (after Wiszniewski 1953) by adding bradymictic lakes (poor water mixing) and tachymictic lakes (fast mixing of water)." Paper is added as PDF.

Dr. Geller is right. The term bradymicitic refers to lakes that are not disturbed and retained their original conditions. This may refer to water layers and their physico chemical conditions too.
