Fargo, N.D. — A paper co-written by Kenneth Lepper, associate professor of geology at NDSU, recently was named an “Editors Choice” selection by the Canadian Journal of Earth Sciences.

The article, “A Sault-outlet-referenced mid- to late-Holocene paleohydrograph for Lake Superior constructed from strandplains of beach ridges,” was selected for the journal’s November issue. 

According to Lepper, the paper “presents a paleohydrologic record of lake level change in Lake Superior from 4,500 years ago to the present day. This geologic data provides a baseline for understanding how Lake Superior and other large lakes may respond to changing climate.” 

Other authors included John W. Johnston of the University of Toronto Mississauga, Erin P. Argyilan of Indiana University Northwest, Todd A. Thompson of Indiana University, Steve J. Baedke of James Madison University, Douglas A. Wilcox of SUNY-The College at Brockport, and Steven L. Forman, University of Illinois at Chicago. 

The Canadian Journal of Earth Sciences, published since 1963, is a monthly journal that reports current research related to such topics as climate and environmental geoscience; geoarchaeology and forensic geoscience; geochronology and geochemistry; geophysics; hydrology; mineralogy and petrology; planetary geoscience; soil sciences; and structural geology and tectonics. 

NDSU is recognized as one of the nation's top 108 public and private universities by the Carnegie Commission on Higher Education.
