Santa Catalina Mountains - Marshall Gulch Soil Solution Chemistry 2009-2010 (Arizona, USA)

In the Marshall Gulch of the Catalina-Jemez Critical Zone Observatory (CZO) there are installed 8 Soil Moisture suction cups in the schist site and 7 in the granite site in both convergent and divergent landscape positions. These soil solution samplers are co-located with piezometers measuring water table depth within the soil profile. Soil Moisture suction cups (SoilMoisture Equipment Corp., Santa Barbara, CA) are sampled with a suction of 70-80kpa and optimized for all chemistry analyses with the exception of dissolved organic matter in the case of the Soil Moisture ones (due to potential sorption of DOM on the porous ceramic material).

在卡塔利娜-杰梅兹关键带观测站（CZO）的马尔什峡谷中，石英岩地点安装了8个土壤湿度吸盘，花岗岩地点安装了7个，且这些吸盘均位于汇聚和发散的景观位置。这些土壤溶液采样器与测量土壤剖面中地下水位深度的压力计共位。土壤湿度吸盘（SoilMoisture Equipment Corp.，圣巴巴拉，加利福尼亚州）以70-80kpa的吸力进行采样，并针对除土壤湿度吸盘所采集的溶解有机物（由于可能存在溶解有机物在多孔陶瓷材料上的吸附）以外的所有化学分析进行了优化。
