Soil Pit Sensor Data, Volumetric Water Content and Temperature, Far North Queensland Rainforest SuperSite, Daintree Rainforest Observatory, Cape Tribulation, 2009

A soil pit was dug to 1.5 m depth in July 2007 and monitoring probes were installed at 0.1, 0.75 and 1.5 m depths in three columns. At each depth there were 3 time domain reflectometry probes (Campbell Scientific CS616) to measure volumetric water content, 3 gypsum blocks (Measurement Engineering Australia GBHeavy, except at 0.1 m depth were there were only 2) to measure water potential over the range -30 to -600 kPa. In addition one TCAV thermocouple probe to record soil temperature was located in the centre of the soil pit at 0.10m. In each column the time domain reflectometry and gypsum blocks were separated laterally by 20cm, each column was separated from the next by 100cm. At each depth the time domain reflectometry and gypsum blocks were separated laterally by 1 m.

2007年7月挖掘了一座深度达1.5米的土壤剖面坑，并在3根监测立柱的0.1 m、0.75 m及1.5 m深度处安装了监测探头。每处深度均布设3台坎贝尔科学（Campbell Scientific）CS616型时域反射仪（time domain reflectometry）探头，用于测定土壤体积含水量；同时设置3块澳大利亚测量工程公司（Measurement Engineering Australia）GBHeavy型石膏块，用于测量-30 kPa至-600 kPa量程内的土壤水势，仅0.1 m深度处仅设置2块该类石膏块。此外，在土壤剖面坑中心的0.10 m深度处，安装了1支TCAV型热电偶探头以记录土壤温度。每根监测立柱内的时域反射仪探头与石膏块横向间距为20 cm，相邻监测立柱之间的间距为100 cm；而各深度处的时域反射仪探头与石膏块横向间距均为1 m。
