RECENT NEWS:

Spring 2014:

Emily Seelen '13 was awarded a NSF graduate fellowship (link)!

We started a new project this spring in cooperation with Nate Johnson's group at the University of Minnesota-Duluth.  We are examining the impact on MeHg production of using dredged material to create shallow water habitat in areas of the St Louis River Estuary.  We are also taking the opportunity to collect more dragonfly larvae and other biota within the estuary to compare with recent data from further upstream in the St Louis River.

January 2014:

As part of a J-term research class Rachel Weitz '16, Kris Reiser '16, and Russ Krueger '17 completed analysis of serveral hundred dragonfly larvae in rivers and streams within the St Louis River Watershed.  This work is part of an ongoing project examining the impact of elevated sulfate levels on the cycling of Hg within the watershed.

 

Fall 2013:

Alison Agather '13 (Chemistry and Environmental Studies) started graduate school at Wright State University under the direction of Dr. Chad Hammerschmidt. She received a Wright Fellow scholarship to pursue an, M.S. in Earth and Environmental Sciences.

Emily Seelen '13 (Biology and Environmental Studies) started graduate school at the University of Connecticut in the Marine Science Ph.D. program.  Emily is working for Dr. Rob Mason and her project will likely be on Hg methylation near the continental shelf.

Michael Walker '13 (Chemistry, ACS) started graduate school at Washington University in St. Louis in the Energy, Enviromental and Chemical Engineering program under the direction of Dr. Brent Williams.  Michael is working on the atmospheric photochemistry of aerosol particles and is developing new instrumentation to measure changes in black carbon aerosols as they are oxidized in the atmosphere (wow!).

Summer 2013:

Bryan Voigt '16 (Chemistry), Anna Huff '15 (Chemistry, ACS) and Will Metcalf '15 (Geography) worked in the Environmental Chemisry Lab this summer.  Bryan continued Michael Walker's CLE-SPE project, while Anna and Will worked on photochemistry and dragonfly studies related to the DNR study examining the impact of mining discharges of sulfate to the St Louis River and other water bodies.

Michael Walker '13 presents poster entitled "Determination of Methylmercury-Dissolved Organic Matter Binding Constants by Competitive Ligand Exchange Solid-Phase Extraction at the 2013 Association for the Sciences of Limnology and Oceanography (ASLO) in New Orleans. Co-authors were George Aiken (USGS) and Bryan Voigt '16.
