Request Archival Samples

NEON is currently building an online ID system to help data users locate where NEON samples are archived. In the interim, we do have a variety of types of samples available from NEON by request.

Please scroll through the list below to find the archival sample you are looking for:

Excess Soils from Puerto Rico pre- and post-hurricane 2017

The National Ecological Observatory Network (NEON) has excess air-dried soil from our Puerto Rico sites (Guanica Forest and Lajas Experiment Station) collected in 2017 pre and post hurricane. While the sites did not undergo massive hurricane damage, they still received large amounts of rainfall and the forest site lost a number of trees.  

Excess soils may remain after soils are fully processed for physical, chemical and microbial measurements.  NEON does not plan to archive these soils.  However, we may be able to make excess soil available to the research community in an ad hoc fashion and on a first-come-first-serve basis. The amount available in any given month will vary depending upon analytical needs for soils during that month; amounts will also vary across sites and years.  If you are interested in finding out whether there are excess soils available from a particular site, please click the link below.

Soil Microbes (Frozen)

Soil microbial samples are collected from surface horizons (Organic and Mineral) to a depth of 30cm. Microbial samples are frozen after field collection and stored in a temporary archive in ultra-low freezers (-80°C).  This archive is considered a community resource; samples may be requested for scientific and educational purposes. Presently, samples are distributed at various NEON locations temporarily while a permanent archive facility is procured.

Megapit Soil Archive

During the construction of each terrestrial field site, soil was collected from multiple soil horizons at a single soil pit (a "megapit") that was up to 2m deep. These samples serve as a reference of soil physical and chemical conditions at the time the NEON site was constructed.

If you are interested in requesting megapit soil from a particular site or set of sites, please click the link below. In order to balance preservation and sample use, request only the minimum amount of soil needed for your study. Any amount of material may be requested; however, we are more likely to approve requests for smaller quantities of soil per sample (e.g., <20 g per sample). Requests for larger quantities may be approved if justified and the aim of the study passes the merit review.

Associated megapit soil data including soil physical and chemical properties as well as root sampling may be downloaded from the NEON data portal.

Other Samples

Additional NEON samples not listed on this page may be available from external archival and curation facilities, such as museums. NEON is currently building an online ID lookup system to aid users in finding samples. In the interim, if you are interested in discovering whether specific types of samples are available, please contact the NEON Archival Samples Team.
