Diatoms: Collecting Core Samples in Lake Superior

Researchers from the University of Minnesota Duluth's Natural Resources Research Institute collect diatoms in sediment cores pulled from the bottom of Lake Superior to learn more about the history of the largest Great Lake.


Diatoms: Euan Reavie

Euan Reavie, senior research associate at the University of Minnesota Duluth's Natural Resources Research Institute and director of the Ely Field Station, explains his project to reconstruct the long-term history of Lake Superior through the analysis of diatoms in lake sediment cores.


Diatoms: Victoria Chraibi

Have mining, agriculture, and urban development altered Lake Superior's water quality? After analyzing diatom remains trapped in sediment cores Victoria Chraibi, graduate assistant at the University of Minnesota Duluth's Natural Resources Research Institute, says "yes."


Fishing on Lake Superior

Cold, vast and deep, Lake Superior's virtually an inland ocean and it can be a bit foreboding. But at the far western end of the lake, just north of Duluth, Minnesota, a productive harvest is going on virtually year-round: lake herring, a smokehouse favorite. And it takes a special kind of character to brave Superior alone, in an open boat, to chase down this native fish. The America's Heartland Series is produced by KVIE Television, a PBS affiliate.
