Soil and plant tissue archive
Cedar Creek maintains a collection of soil and plant tissue samples collected across the site from 1982 through the present. Samples are stored in vials in an onsite dedicated facility. This collection currently has over 110,000 samples. A complete list is available in a ZIP file here.
Researchers are encouraged to archive extra material from samples being processed for chemical analysis. If possible, one full scintillation vial of material is ideal. Archive ID numbers may be requested from the CDR information manager by providing a complete list of samples, description of contents, where each was collected, and the date and purpose of collection. Labels with Archive IDs and sample metadata are provided. Processed samples in labeled vials are given to CDR research managers, who add them to the archives.
Requests for access to samples should be sent to webmaster@cedarcreek.umn.edu.
