Water stable isotopes for streams and precipitation samples in the HJ Andrews Experimental Forest and Mary's River Watershed, 2014-2016

Water samples have been collected for analysis of water stable isotope (O18/16 and H2/H1) at different locations in the HJ Andrews Experimental Forest and over different periods since 2014. The database includes: 1) water samples collected in the Andrews Forest every 1-3 weeks between 2014 and 2016 in streams (Lookout Creek, Mack Creek, McRae Creek, WS01, WS02, WS07, and WS08) and bulk precipitation from benchmark meteorological stations (PRIMET, MACK, and H15MET). These samples were analyzed; 2) grab samples collected over the mainstream network of the Andrews Forest on three sampling campaigns during baseflow conditions: July-September, 2015, June 2016, and September 2016. In each of the three samplings, the samples were collected at approximately 100-meter intervals in the 2nd to 5th order streams of Cold, Lookout, Mack, and McRae Creeks and 3) stream and precipitation samples collected in the Andrews Forest at high temporal resolution during discrete storm events at Mack Creek in 2015; and 4) water samples collected every 2-3 weeks between 2014 and 2015 at 24 streams and 3 bulk precipitation collectors in the Marys River basin.

自2014年起，研究人员于HJ安德鲁斯实验森林（HJ Andrews Experimental Forest）的不同点位及不同时段采集水样，用于分析水体中的稳定同位素（water stable isotope）组分（O¹⁸/¹⁶与H²/H¹）。本数据库涵盖以下四类数据：
1. 2014年至2016年间，每1~3周在安德鲁斯森林的溪流（卢特溪（Lookout Creek）、麦克溪（Mack Creek）、麦克雷溪（McRae Creek）、WS01、WS02、WS07及WS08）以及基准气象站（PRIMET、MACK、H15MET）采集的溪流水样与集总降水样品（bulk precipitation），所有样品均完成了同位素分析；
2. 在基流条件下，于三次野外采样作业期间采集的安德鲁斯森林干流网络瞬时水样（grab samples）：分别为2015年7—9月、2016年6月及2016年9月。三次采样均在科尔德溪（Cold Creek）、卢特溪、麦克溪及麦克雷溪的2至5级支流中，以约100米的间隔采集水样；
3. 2015年在麦克溪开展的离散暴雨事件期间，以高时间分辨率采集的安德鲁斯森林内溪流与降水样品；
4. 2014年至2015年间，每2~3周在玛丽斯河（Marys River）流域的24条溪流及3个集总降水采集器处采集的水样。
