BCCZO -- Surface Water Chemistry -- (BC_SW_Array) -- Boulder Creek CZO -- (2008-2020)

Surface water samples were collected within the Boulder Creek Watershed at various points along Boulder Creek from 2009 to current. 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+, NH4+, Cl-, NO3-, SO4-, Si, and SiO2 and occasionally included Al+, Fe+, Mn+. Nutrients and organics analyzed mainly included DOC, DON, TDN, IP, PP, DOP, TDP, Phaeophytin, and Chlorophyll-a. Water isotopes analyzed regularly included O18 and D and occasionally included T.
