RCCZO -- Soil Texture, Soil Biogeochemistry -- Soil Properties at the Reynolds Creek Experimental -- Reynolds Creek Experimental Watershed -- (2014-2017)

Soil physical properties, analytical measures and photographs were taken on soils within the Reynolds Creek Experimental Watershed (RCEW), which is an extensively monitored catchment within southwestern Idaho. Samples were collected over a full range of elevation (1187 to 2111 m), vegetation, lithology (granite, basalt, rhyolite, and colluvium), and climate that varies between mean annual temperature (MAT) precipitation (MAP) from 4.7 to 9.2 °C and 233 to 972 mm, respectively. Soils were collected from profiles by genetic horizons and predetermined depth down to ~1 m or mobile-immobile regolith interface. Here, we provide a spatially extensive soil dataset for 93 soil profiles and 560 sub-samples. We make available a complete soil dataset in conjunctions with the System for Earth Sample Registration (SESAR), where all samples have a unique International Geo Sample Number (IGSN).

本数据集采集了爱达荷州西南部长期监测集水区——雷诺溪实验流域（Reynolds Creek Experimental Watershed, RCEW）内土壤的物理性质、分析测定指标及对应影像资料。采样覆盖了该区域完整的海拔梯度（1187~2111 m）、植被类型、岩性（花岗岩、玄武岩、流纹岩及崩积物），以及年均温（mean annual temperature, MAT）4.7~9.2℃、年均降水量（mean annual precipitation, MAP）233~972 mm的气候区间。土壤样品按发生层及预设深度从土壤剖面中采集，采样深度至约1米或活动-非活动风化层界面。本研究公开一套空间覆盖范围广泛的土壤数据集，包含93个土壤剖面及560个次级采样样品。该完整土壤数据集已与地球样品注册系统（System for Earth Sample Registration, SESAR）完成关联，所有样品均配有唯一的国际地质样品编号（International Geo Sample Number, IGSN）。
