Hubbard Brook Sample Archive

Hubbard Brook Archive Building

The Hubbard Brook Physical Archive was completed in 1990 to permanently store research samples for future use in Hubbard Brook studies. The building provides a special and unique opportunity to maintain a research memory for long term ecosystem studies. The storage facility consists of two rooms, a larger unheated room and a smaller room heated to just above freezing in the winter. The smaller room was designed to store the chemical control water samples from watershed 6 and rain gage 11 in order to protect against chemical changes due to freezing. All other samples are stored in the larger room and subjected to a large range in temperature and humidity. Steel shelving is used to house the samples.

Interior of Hubbard Brook Sample Archive

Samples are accepted into the archive system if they are likely to be of future use, they are accompanied by adequate documentation, and sampling sites are known. The archive building now houses approximately 40,000 samples of soil, water, plant tissue, and other materials. Samples are preserved, barcoded, and cataloged with accompanying metadata in a database. Some of the collection has been barcoded and cataloged in a searchable database posted on the Hubbard Brook website. We are currently in the process of adding more samples to the database and making them available on-line.

Requests for reanalysis of archived samples (e.g. isotopic analyses, heavy metals, etc.) are received periodically, and have resulted in a number of publications.

In 2006, the sample archive building was dedicated to Cynthia A. Veen, who served as the HBES information manager from 1988 to 1996.

If you wish to archive samples that you have collected, please refer to the directions for submitting samples.

If you wish to use the samples in the collection, please view the subsampling policy and fill out the subsampling request form.

Directions for Sample Submission

Requirements for acceptance of samples:

  1. Adequate documentation must accompany physical samples.
  2. Samples are stored in either an unheated large room or a smaller room that is heated to just above freezing. The contributing scientist is responsible for deciding that these conditions are suitable for his/her samples.
  3. Soil samples must be air or oven-dried and stored in plastic or glass bottles with screw caps to ensure a tight seal. No cardboard containers please.
  4. Vegetation samples should be dried, ground and stored in clear plastic or glass containers.
  5. Water samples must be stored in plastic bottles and will be accepted either poisoned or not poisoned. If poisoned, the investigator must specify the type and concentration used.
  6. All logs, cookies and cores should be air-dried and can be stored in cardboard boxes or arranged in a manner that will allow for air to flow between individual samples. Tree cores should be mounted or stored in straws.
  7. Samples that are considered toxic may be rejected. The data management committee may confer with the SAC about important, but toxic samples requiring storage.

Sample Archive Subsampling Policy

We are happy to share these archived samples with responsible scientists. We take subsampling and the dissemination of the associated data very seriously. As stewards of these samples, our highest priorities are:

  1. to maintain the chemical integrity of these samples;
  2. to document the use of these samples, and any resulting changes;
  3. inform principal investigators of interest in using them;
  4. to acknowledge the appropriate funding sources for their original collection.

We ask that you adhere to the following guidelines as matter of common courtesy and ethical responsibility:

  1. Please fill out this form as completely and carefully as possible.
  2. Please allow time for the Information Management Subcommittee (IMSC) to route this request to the PI for approval.
  3. Please allow the original PI the option to review or participate in any publication that makes extensive use of the data provided from any reanalyses.
  4. Please cite the funding sources that supported the original collection and storage of these samples, in any publication resulting from this research.

Initiate a request for subsampling by completing his form, and returning it to Amey Bailey (contact info above).
