Gordon Gulch - Surface Water Chemistry - (GG_SW_Array) (2008+)

Gordon Gulch Surface Water Chemistry. Group ID GG_SW_Array


Surface water samples were collected within the Boulder Creek Watershed in Gordon Gulch from 2009 to current. Throughout the year, samples were regularly collected at two stream sites and at two spring sites. During the spring and summer, daily samples were collected via autosampler. 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 regularly included H+, Ca+, K+, Mg2+, Na+, Cl-, NO3-, SO4-, Si, and SiO2 and occasionally included NH4+, Al+, Fe+, Mn+. Nutrients and organics analyzed mainly included DOC, IN, DON, TDN, IP, DOP, and TDP. Water isotopes analyzed included O18 and D.


From 2009 to 2011, Gordon Gulch surface water samples were analyzed by the Kiowa Laboratory (conductivity, alkalinity, cations, anions, O18, and deuterium) and by the Organic Matter Spectroscopy Laboratory (nutrients and organics). From 2011 to present, Gordon Gulch surface 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).
