CALHOUN CRITICAL ZONE OBSERVATORY

The majority of my Master's research took place at the Calhoun Critical Zone Oberservatorty (CCZO, or Calzone). My focus was on characterizing the spatial and temporal variation in soil moisture using non-invasive, geophysical techniques, and then relating that soil moisture variability to  iron redox dynamics. My project at the Calzone is two-part: (1) I sought to characterize the spatial and temporal variability (esp. seasonal) in iron reduction in three first-order watersheds; and (2) to understand the relative importance of iron reduction to soil respiration as watersheds increase in size (move from headwater streams, to large high-order rivers), and respond to climate change
