Alternate Identifier:DOI PLACE HOLDER
Abstract:

These data are monthly fluxes of solutes in stream water measured in watersheds of the Hubbard Brook Experimental Forest and are a part of the Hubbard Brook Watershed Ecosystem Record (HBWatER), which is a long-term record of stream and precipitation chemistry and volume. The solute fluxes in stream water are calculated as the product of the volume of stream water and solute concentrations. There are nine gaged watersheds at the Hubbard Brook Experimental Forest, some of which have been subjected to experimental manipulations. The calculation of fluxes is currently supervised by John Campbell (US Forest Service). The long-term stream water record is collected and maintained by the US Forest Service. The collection and management of the long-term stream and precipitation chemistry record was initiated in 1963 by Gene E. Likens, F. Herbert Bormann, Robert S. Pierce, and Noye M. Johnson. HBWatER is currently sustained by Tammy Wooster (Cary IES) and Jeff Merriam (USFS) and the dataset is curated and maintained by a team of researchers: Chris Solomon (Cary IES), Emma Rosi (Cary IES), Emily Bernhardt (Duke), Lindsey Rustad (USFS), John Campbell (USFS), Bill McDowell (UNH), Charley Driscoll (Syracuse U.), Mark Green (Case Western), and Scott Bailey (USFS). Current Financial Support for HBWatER is provided by NSF LTREB # 1907683 and the USDA Forest Service Northern Research Station.

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.

Methods and protocols used in the collection of this data package
Description:

The stream flux calculation method traditionally used at the Hubbard Brook Experimental Forest is a period-weighted approach that involves multiplying the chemical concentration (mg L−1) for each sample date by the daily stream flow (mm d−1) for that day. For days between sampling dates, the average of the previous and subsequent concentrations is multiplied by the daily streamflow (Buso et al. 2000). Samples for chemical analyses are generally collected on a weekly basis. Ionic fluxes are provided (e.g., NO3-) rather than element fluxes (e.g., NO3--N). Daily fluxes are aggregated into the monthly values provided; however daily flux data are available on request by contacting John Campbell (john.campbell2@usda.gov). Please see the chemistry (https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=208) and streamflow (https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=2) metadata for a description of the data used in these calculations. A description of the gaged watersheds and the experimental treatments can be found at https://hubbardbrook.org. Current detection limits for chemical analyses are available at https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=215. Historical detection limits and additional methodological details are provided in Buso et al. 2000
