Hubbard Brook Experimental Forest: Synoptic Surface Water Chemistry, 2015

This dataset presents field and analytical data collected during a synoptic surface water sampling survey on July 22-23, 2015. Watershed 3, watershed 9, and the upper west branch of Zig Zag Brook were included. Some results from these three catchments were published by Bailey et al. 2019, Frontiers in Earth Science. Additional sampling sites not included in this publication were on Paradise Brook, between weir 3 and its outlet to Hubbard Brook, and along the main stem of Hubbard Brook in the western portion of the valley. Sampling sites are designated as stream sites or seeps. Seeps are either off of the stream channel or are at anomolously perennial channel initiation points and are presumed to represent "longer, deeper" flowpaths where groundwater discharges to the surface. Seeps are typically characterized as having relatively low water temperature in the summer, and with chemistry contrasting from adjacent stream sites. 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.
