Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Natural abundance stable isotopes of oxygen, hydrogen, and deuterium-excess in branch xylem water were measured within the Climate Change Across Seasons Experiment (CCASE) plots. There are six plots total (each 11 x 14 m). Two are warmed 5 degrees C throughout the growing season (Plots 3 and 4). Two others are warmed 5 degrees C in the growing season and have snow removed during winter to induce soil freezing and then warming cables turn on to create thaws; each soil freeze/thaw cycle includes 72-hours of soil freezing followed by 72-hours of thaw (Plots 5 and 6). Four kilometers (2.5 mi) of heating cable are buried in the soil to warm these four plots. Two additional plots serve as controls for our experiment (Plots 1 and 2). This data set includes natural abundance stable isotopes of oxygen, hydrogen, and deuterium-excess in branch xylem water from 2018. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
