Water isotope samples from Watershed 3 at Hubbard Brook Experimental Forest, 2006-2010

This dataset presents biweekly water isotope samples collected throughout the year during October 2006 to October 2010 from eight fluxes and stores in a headwater catchment at the Hubbard Brook Experimental Forest, New Hampshire, USA. Samples of precipitation, snowmelt, soil water, and stream water were collected over the entire four-year period. Throughfall and snow pack sampling was discontinued after two years, and groundwater sampling began in the second year and continued through the end of the monitoring period. Precipitation samples were collected in an existing rain gage clearing at an elevation of 564 meters. 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.
