Hubbard Brook Experimental Forest: Longitudinal surveys of stream nitrate concentrations, W1, W3, and W6, Summer 2015

Detailed surveys of stream nitrate concentrations in the calcium-enriched (W1), hydrologic reference (W3), and biogeochemical reference (W6) watersheds were performed in the summer of 2015 with the goal of identifying "hotspots" of NO3- inflows into streams. Additional details on methods and analysis can be found at: Marinos, R. E., Campbell, J. L., Driscoll, C. T., Likens, G. E., McDowell, W. H., Rosi, E. J., Rustad, L. E., & Bernhardt, E. S. (2018). Give and Take: A Watershed Acid Rain Mitigation Experiment Increases Baseflow Nitrogen Retention but Increases Stormflow Nitrogen Export. Environmental Science & Technology, 52(22), 13155–13165. https://doi.org/10.1021/acs.est.8b03553 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 US Forest Service, Northern Research Station.
