BCCZO -- Surface Water Chemistry -- (GG_SW_Array) -- Gordon Gulch -- (2008-2020)

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.

自2009年起，对博尔德溪流域戈登谷中的地表水样进行了采集。全年中，在两个溪流采样点和两个泉眼采样点定期收集样本。春季和夏季，通过自动采样器每日收集样本。样本由博尔德溪流域地球化学观测站的水化学实验室使用0.45µm和1µm的滤膜进行过滤。对样本进行了电导率、主要离子、碱度、营养物质和有机物以及水同位素的检测。常规分析的主要离子包括H+、Ca+、K+、Mg2+、Na+、Cl-、NO3-、SO4-、Si和SiO2，偶尔还包括NH4+、Al+、Fe+和Mn+。检测的营养物质和有机物主要包括DOC、IN、DON、TDN、IP、DOP和TDP。分析的水同位素包括O18和D。传感器阵列ID及描述如下：- GGL_SW_0，样本采集：人工，水化学，溪流水采样点。- GGL_SW_0_ISCO，样本采集：自动化，水化学，ISCO自动水采样器。- GGU_SW_0，样本采集：人工，水化学，溪流水采样点。- GGU_SW_0_ISCO，样本采集：自动化，水化学，ISCO自动水采样器。- GGU_SPW_1，样本采集：人工，水化学，溪流水采样点。- GGU_SPW_2，样本采集：人工，水化学，溪流水采样点。数据中包含空白样本，并带有时间戳的ISCO样本，例如GGL_SW_0_ISCO 1300，GGL_SW_0_ISCO 1500等。
