Precipitation chemistry has been measured at the Hubbard
Brook Experimental Forest since 1963. This data set
includes volume-weighted, average, monthly concentrations of
cations, anions, and pH for watershed 8. Monthly averages are calculated from
samples collected at weekly intervals from several bulk
precipitation stations located in the experimental watersheds.

Data Access Guidelines for Streamwater Chemistry
We are happy to share these data on the chemistry of Hubbard Brook ecosystems. The public dissemination of these data that we have collected is a responsibility that we take very seriously. As stewards of these long-term data, our highest priorities are:
a. to maintain the integrity of these long-term data;
b. to allow adequate time for the analysis, quality assurance, and publication of results by principal investigators;
c. to acknowledge properly and responsibly the appropriate funding sources.
Therefore, it is HBES policy to make these streamwater data available on this web page two years after the date of collection. Also, in sharing these data with users like yourself, we ask that you adhere to the following guidelines as a matter of common courtesy and ethical responsibility:
1. Please inform us in advance of your interest and plans for use of these data (LikensG@ecostudies.org).
2. The sources of funding used to collect these data must be acknowledged properly. We will provide the appropriate information when we learn what data are being used.
3. We would like to review any manuscripts that utilize extensive amounts (e.g. multiple years) of these data. If data use is extensive, or if these data have not been published previously, it may be appropriate for us to be included as authors on publication that are generated given the additional requirements from us for analysis and interpretation.
Data Use Policy
The re-use of scientific data has the potential to greatly
increase communication, collaboration and synthesis within and among
disciplines, and thus is fostered, supported and encouraged. Permission to
use this dataset is granted to the Data User free of charge subject to the
following terms:
1) Acceptable use. Use of the dataset will be restricted to academic, research,
government or other not-for-profit professional purposes.
2) Redistribution. The data and metadata are provided for use by the Data User.
The Data User will not redistribute the original Data Set or metadata to
others without the explicit permission of the Principal Investigator.
3) Citation. It is considered a matter of professional ethics to acknowledge the work
of other scientists. Thus, the Data User will properly attribute
the Data Set in any publications or in the metadata of any derived data products
that were produced using the Data Set. Citation should take the
following general form: Creator, Year of Data Publication, Title of Dataset,
Publisher, Dataset identifier.
Citation example: Holmes, R.T. 2012. Bird Abundances at Hubbard Brook (1969-2010)
and on three replicate plots (1986-2000) in the White Mountain

4) Acknowledgment: The Data User should acknowledge any institutional support or specific
funding awards referenced in the metadata accompanying this
dataset in any publications where the Data Set contributed to its content. Acknowledgments
should identify the supporting party, the party that received
the support, and any identifying information such as grant numbers.
Acknowledgment example: Data on [topic] were provided by [name of PI] on [date].
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, Newtown Square, PA. Significant funding for collection of these
data was provided by [agency]-[grant number], [agency]-[grant
number], etc.
5) Consultation and questions. Data users are strongly encouraged to consult with the Principal
Investigator(s) who collected these data for further information. Also, when appropriate,
Data Users should consider including the Principal Investigator as a collaborator and/or co-author
in the use of these data.
6) Notification. The Data User will notify the Principal Investigator of any publication or
derivative work based on the Data Set. The Data User will
also provide the Principal Investigator and/or the administrator of the Hubbard Brook
Ecosystem Study with a pdf or two reprints of any publication(s)
resulting from use of the Data Set.
7) Disclaimer. While substantial efforts are made to ensure the accuracy of data
and documentation contained in this Data Set, complete accuracy of data and
metadata cannot be guaranteed. All data and metadata are made available "as
is". The Data User holds all parties involved in the production or
distribution of the Data Set harmless for damages resulting from its use or
interpretation.
8) Terms of Agreement. By accepting this Data Set, the Data User agrees to abide by the
terms of this agreement. The Data Owner shall have the right to terminate
this agreement immediately by written notice upon the Data User's breach of,
or non-compliance with, any of its terms. The Data User may be held
responsible for any misuse that is caused or encouraged by the Data User's
failure to abide by the terms of this agreement.

HBEF watershed 8 (WS-8). Primary bulk collector located at HBEF RG-19 (elev. 600m above MSL) 20m west of WS-8 stream gauging station. Data from this site are used to provide chemical inputs for HBEF watersheds 7, 8, and 9, based on precipitation volumes in each of those watersheds. Coordinates given correspond to watershed 8.

SAMPLING DESIGN
Continuously-open, bulk collectors (clean plastic funnels-bottles in summer; 21-liter plastic buckets in winter) mounted on posts approximately 2 m above land surface within cleared openings in the forest. Samples are collected weekly, and all collection gear is acid-washed, de-ionized water-rinsed, and exchanged each week, regardless of whether precipitation occurs or not. Measurements of pH are determined at HBEF; ion analyses conducted at the Institute of Ecosystem Studies in Millbrook, NY.
Daily deposition values (in g/ha-mo) are derived by multiplying daily precipitation amounts (in mm) for Watershed 8, by the average weekly concentration of solutes from the bulk collectors (in mg/L) for the same period. Daily values are summed to produce monthly deposition, and deposition divided by total monthly precipitation to produce volume-weighted, average monthly concentrations for precipitation at HBEF WS-8.
In June 2013, after careful inter-laboratory comparisons, chemical analyses
were transferred from the Cary Institute of Ecosystem Studies Lab to the
USDA Forest Service Lab in Durham, NH. Samples are split into 3
aliquots for different analyses. Monomeric Aluminum is measured on an
unfiltered-refrigerated aliquot using an automated Pyrocatechol Violet method.
A filtered-refrigerated aliquot is acidified and analyzed for cations and
metals using ICP-OES (USEPA 200.7). A filtered-frozen sample is used for
measuring NH4 (USEPA 350.1 Rev. 2.0), PO4 (USEPA 365.1 Rev. 2.0),
Anions (USEPA 300.1) , DOC (USEPA 450.1) and TDN (High Temperature Catalytic
Oxidation with chemiluminescent N detection).
