Abstract
In situ freeze-coring of sediment from the central point of Laukunlampi, a small meromictic seepage lake in E Finland, shows that the sediment is composed of regularly repeated laminae. Diatom and chrysophyceae analysis indicate that the alternating light and dark laminae in the uppermost sediment recur on an annual basis and can be regarded as varves. In some years additional white (diatom) , black (organic matter) or green (green algae) bands occur. Almost all the material in the sediment is autochthonous. A seasonal model is proposed to account for these deposits.-from Author
