Throughfall and Isotopic Ratios on WS1 at the Andrews Experimental Forest, 2010-2011

The data in this set describes the throughfall collection on WS1 during 2010 and 2011, as well as the isotopic data assessed from these samples. In the Fall of 2010 there were eleven collection periods and in the Spring of 2011 there were eight collection periods. Data is no longer being collected. Throughfall and rainfall were measured at point locations, measured for the quantity and isotopic composition (Oxygen-16/18 and Hydrogen/Deuterium). Stemflow was also collected off of two PSME trees, one on the north-facing and one on the south-facing slope. These are the "plots" for this study, although they have no defined radius. During the Fall 2010 collection period, thirteen collectors were used, near the stream channel, along the trail in WS1. During the Spring 2011, there were eighteen collectors at each of two plots. Rainfall was also measured in an opening at the WS1 landing for comparison.

本数据集记录了2010年至2011年间WS1样地的穿透雨（throughfall）收集情况，以及从对应采集样本中分析得到的同位素数据。2010年秋季共开展11次采样周期，2011年春季则开展8次采样周期，目前已停止数据采集工作。研究在点位处测定了穿透雨与降雨的总量及其同位素组成（氧16/氧18与氢/氘）。此外，团队还从2棵PSME树种上收集了茎流（stemflow），其中1棵位于北坡，另1棵位于南坡——这2棵树即为本次研究的"样地"，但未设定明确的样地半径。2010年秋季采样期间，研究人员在WS1样地的溪流河道附近、步道沿线共布设了13个收集器；2011年春季采样时，两个样地各布设了18个收集器。为便于对比分析，研究人员还在WS1平台的开阔区域内布设设备测定了降雨数据。
