SERC InTeGrate Project

The Science Education Resource Center (SERC) works to improve education through projects that support educators. InTeGrate is a specific SERC project funded by a 5-year STEP Center grant from the National Science Foundation. The program supports the teaching of geoscience in the context of societal issues both within geoscience courses and across the undergraduate curriculum. Our goal is to develop a citizenry and workforce that can address environmental and resource issues facing our society.

Northfield Energy Task Force

The Northfield Energy Task Force (NETF) was created by resolution of the Northfield City Council in May 2007 to respond to challenges presented by reliance on fossil fuels and climate change. Their report, “With Hope: A Resilient Community” was presented to the City Council in May 2008, but follow-up was limited due to other political priorities at the time.

Study of Agricultural Tillage Practices

 Description: Undergraduate collaborators work directly with faculty, the CRWP, and area farmers to examine the effects of different agricultural practices on soil quality and agricultural yields. Past research has examined water runoff and the diversity of invertebrate soil fauna associated with different tillage methods, especially no-till and strip-till. Lands owned by farmer participants as well as St. Olaf College are used as field sites. In additional a special project examined tillage practices and carbon sequestration with the possibility of local carbon offsets. Recent research has focused on exploring how differences in applied nitrogen fertilizer translate into soil nitrogen levels, stalk nitrate levels, and product yield. Additionally, research work focuses on general indicators of soil quality including moisture levels, compaction, organic carbon and nutrients, including nitrogen and phosphorous.

Participants:

  • David Legvold, farmer
  • Gene Bakko, St. Olaf College (retired)
  • Kathleen Shea, St. Olaf College
  • Megan Gregory ‘04, St. Olaf College

Wading Through the Muddy Floodwaters: Social Vulnerability to Flooding in Northfield, MN, A Case Study

Many researchers have studied social vulnerability in coastal cities and at large scales, yet few have conducted investigations on a smaller scale. This study characterizes the current social vulnerability to flooding of Northfield, Minnesota, a small river town using the frameworks of Blaikie et al.’s (1994) social vulnerability definition and Cutter et al.’s community resilience dimensions (2008). Our methodology combines archival and interview analysis. Archival analysis illustrates that flooding has often been a risk to the economy, infrastructure, and people of Northfield. Interview analysis, through the lens of experts, residents, and business owners, shows how the community anticipated, coped with, resisted, and recovered from recent flood events. We generated 15 factors to characterize Northfield’s current social vulnerability to flooding, which generally fit into Cutter et al.’s dimensions (2008). We argue that Blaikie’s et al.’s (1994) definition and Cutter et al.’s (2008) dimensions are helpful frameworks to examine social vulnerability to environmental hazards in small communities. We also make policy suggestions for Northfield based on our 15 factors. We hope this study provide insights into flood management and research for Northfield and other small towns in Minnesota.

Carleton College Wind Turbines

Aided by momentum from community organizations like ReNew Northfield, Carleton installed its first, 1.65-MW wind turbine in 2004, a 1.65 MW Vestas V87.  The electricity produced by the first turbine is sold back to our energy provider Xcel Energy, and provided to the public utility grid.

Carleton’s second wind turbine is a 1.68 MW GE XLE, built in 2011 thanks to a generous grant in 2008 from environmentally-minded alumni Richard and Laurie Kracum.  The second turbine is connected directly to the campus grid and provides approximately 25% of Carleton’s annual electricity consumption.

Each turbine produces 4,000- 4,500 MWh of electricity per year.
