facebookISU Paleolimnology Laboratory     

Stone Paleolimnology Laboratory People 2012-2013 Coring at St. Mary of the Woods

Our laboratory specializes in using fossil and modern diatom assemblages to reconstruct past lake and river environments. Undergraduate student research projects in the lab currently include studying the effects of acid mine drainage on lake and river ecosystems and reconstructing the effects of industrial and domestic pollution on lakes and rivers throughout Indiana. Graduate projects range from the Rocky Mountains to East Africa and cover periods from as recent as the last century to as long as 6 million years ago.

Long-term research objectives for the laboratory include development of the diatom paleoecology from Hominid Sites and Paleolakes Drilling Project, which seeks to obtain sediment cores from several of the most important fossil hominin and early Paleolithic artifact sites in the world, located in Kenya and Ethiopia. Additional research objectives in Africa include analysis of paleolake Mababe (Botswana), and developing research for drilling Lake Tanganyika. Continuing lake research in North America ranges from the Rocky Mountains to Alaska. 

Student Success


Congratulations to Kendra Reininga, who recently accepted a job offer from an environmental consulting firm located in Indiana, Creek Run. She will begin work shortly after graduating later this semester. Kendra has been involved with environmental research at the ISU Paleolimnology Lab for the past 2 years and she has worked on lake projects at Shakamak State Park and northwestern Indiana, and is currently also working as a student research assistant on the NSF funded HSPDP study at Baringo Basin.

Recent Publications

     This publication stemmed from some of our research on alpine lakes and the influence of nitrogen on diatom populations. Krista was a PhD student at the University of Maine and our time there overlapped. This project brings a long-term perspective to the influence of meltwater on changes in fossil diatom assemblages.
