The tour will provide all participants a virtual visit to the Spruce and Peatland Response Under Changing Environments (SPRUCE) experiment and participate in active discussion of the ongoing research and research findings to date. The SPRUCE experiment is a US DOE-funded complex large-scale temperature by elevated CO2 manipulation study located within an ombrotrophic bog, regrowth forested peatland in northern Minnesota. Participants will get to virtually experience the complexity and size of the SPRUCE experiment via overflights, video walk throughs of the site and warming enclosures, and a combination of video and slide-based discussions of the various measurement systems used to assess microbe-to-tree responses to the manipulations. We will also include a summary of working hypotheses and discussions of the findings of the SPRUCE research group after more than 5 years of continuous manipulations.
