Soil water samples were collected from lysimeters within the Boulder Creek Watershed in Gordon Gulch from 2011 to 2012. Samples were filtered by Boulder Creek CZO Water Chemistry Lab with 0.45µm and 1µm filters. Samples were analyzed for conductivity, major ions, alkalinity, nutrients and organics, and water isotopes. Major ions analyzed included H+, Ca+, K+, Mg2+, Na+, NH4+, Cl-, NO3-, SO4-, and SiO2. Nutrients and organics analyzed mainly included DOC, DON, TDN, IP, DOP, and TDP. Water isotopes analyzed included O18 and D.
From 2011 to 2013, Gordon Gulch soil water samples were analyzed by the Boulder Creek CZO Lab (conductivity, alkalinity, and anions), the Organic Matter Spectroscopy Laboratory (nutrients and organics), the Laboratory for Environmental and Geological Sciences (cations), and the Barnard Ecohydrology Lab (O18 and deuterium).
