Dataset Information

This page provides summary and descriptive information about the contents of the NSCN Database. Documentation describing data policy, quality assessment, variable names, and basic methods for accessing and browsing datasets is available from the pull-down menu under the 'Dataset Information' link in the menu bar above. Access to the contents of the database requires NSCN membership and is available via the 'Data Browsing' link in the menu bar above.

• Map of sites in the database- each point denotes a site represented in the database

• Database summary statistics (download)- distribution of sites, profiles, and layers in the database; list of contributors with number of sites visited by each

• Carbon data availability (download)- counters showing number of layers per profile, number of layers in each profile that have %C, bulk density, and SOC values, and whether each profile has its computed C stock respresented in the Carbon to 1m data report. 

• Non-Carbon data availability (download)- counters showing number of layers per profile, number of layers per profile with non-carbon data (e.g., %N, particle sizes)
  

• Site and Profile information (download)- site and profile-level ecological, geographic and other metadata, contributor information

The NSCN Database is based on the prototype developed by the Alaska Deep Soil Carbon Project. Summary and descriptive information for the Alaska dataset are available in the reports below.

• Alaska Database summary statistics (download)- distribution of Alaska sites, profiles, and layers in the database; list of contributors with number of sites visited by each

• Alaska Site and Profile information (download)- specific to the Alaska Deep Soil Carbon Project dataset, same variables as above

The NSCN database is a work in progress. We are continually refining and searching for ways to improve all aspects of database functionality. Please email feedback to nscn-support@george.lbl.gov, or post to our forum topic on known database problems.

Please contribute some of your data to this effort! To get started, visit our data contribution page, where you can download templates and guidelines, or contact the Network Coordinator.
