BOREAS TGB-12 CARBON DIOXIDE ISOTOPIC CONTENT DATA OVER THE NSA
Get Data

Summary:

The BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites to estimate the rates of carbon accumulation and turnover in each of the major vegetation types. This data set contains information on the carbon isotopic content of carbon dioxide sampled from soils.

A guide document which includes more information about this data set can be found at http://daac.ornl.gov/boreas/TGB/tgb12ci/comp/TGB12_Iso_CO2.txt.

ORNL DAAC maintains information on the entire BOREAS Project.
