In the second segment of a three-part video series on Great Lakes dead zones, Heidelberg University senior research scientist Pete Richards discusses recent research on the role of dissolved phosphorous and why it may be causing new problems. Richards focuses on Lake Erie, which has a long history of high algal growth and low oxygen.
Part I of the series is here.
Part III is here.
Richards and Graham Environmental Sustainability Institute director Don Scavia recently hosted a workshop on new clues about why the rates of agricultural nutrients are on the rise in the Great Lakes watershed.
This workshop was part of the Agricultural Conference on the Environment held at The Lansing Center on Jan. 27. 2011.
