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:

1. to maintain the integrity of these long-term data;
2. to allow adequate time for the analysis, quality assurance, and publication of results by principal investigators;
3. to acknowledge properly and responsibly the appropriate funding sources.

Therefore, it is HBES policy to make these streamwater data available on this web page five 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.
