Faculty Dataset for Nitrogen biogeochemistry of headwater catchments underlain by discontinuous permafrost lesson plan

Students work with a large dataset describing nitrogen<br>dynamics in the Caribou-Poker Creeks Research Watersheds,<br>small watersheds in the boreal forest that are underlain with<br>various extents of permafrost cover. Students use spreadsheet<br>and graphics software to investigate responses of N cycling to<br>permafrost, seasonal patterns, and inter-annual variation by 1)<br>making observations concerning long (inter-annual) and short-<br>term (seasonal) patterns in nutrient concentrations in streams, 2) hypothesizing about physical and biological conditions influencing nitrogen chemistry, and 3) testing predictions using graphical analyses. The first activity provides a guided approach to addressing a research question with the available data. Supplemental activities are inquiry-based and instructors can either specify analyses to perform or choose to allow students to gain experience with exploratory data analysis in more advanced courses.
