Oxygen isotope in plants and source water between 2018 and 2020, along the Santa Clara River, CA

This data package includes two data tables: 1. the oxygen stable isotope values for plant xylem, soil, groundwater, precipitation; and 2. the environmental conditions between 2018-2020, including precipitation, groundwater depth, potential evapotranspiration, and soil moisture. Isotope data were collected monthly at three sites along the Santa Clara River, CA between 2018 and 2020.

本数据包包含两张数据表：1. 植物木质部、土壤、地下水及降水的氧稳定同位素值；2. 2018年至2020年的环境条件数据，涵盖降水量、地下水埋深、潜在蒸散发与土壤含水量。同位素数据于2018至2020年间，在加利福尼亚州圣克拉拉河沿岸的三个监测点位按月采集。
