Project Description: |
This project develops a robust; flexible; non-invasive;
scanning system for monitoring and verifying temporal changes in soil carbon
in situ over large areas. The
objectives of this project are: (1) to design and construct a continuous Soil
Carbon Scanning (SCS) system for field measurements; and (2) to characterize;
calibrate and test the SCS system in a calibrated sand pit and in well characterized
fields. The method is based on Inelastic Neutron Scattering (INS) of fast
neutrons from the carbon nucleus and detection of the subsequently emitted
4.4 MeV gamma rays.
Proof-of-principle has been demonstrated in a double blind studies at
three different sites where the results of an INS system were compered successfully versus chemical analysis of core
samples taken from the same place. The results from feasibility studies
suggested that the requirement to measure changes of 100
gC/M2 could be met with a precision of about 5%. The proposed system
will be towed in the field at normal speeds of 5 to 10 mph. Since the events
of inducing carbon gamma radiation are very fast; below a microsecond; at
these scanning speeds the soil is being analyzed continuously resulting in a
measurement of the true carbon mean value over the measured area. In the
future the system performance can be improved by using taged
neutrons from a system that is being developed. The scanning times of large
fields will depend on the final footprint that is covered by a single pass of
the system. The anticipated benefit from such a system is its capability to
monitor belowground carbon balances without disturbing the soil. Furthermore;
the system enables continuous scanning of large areas thus providing a true
mean carbon concentration in soil. The proposed system enables for the first
time repetitive measurement of the same site resulting in sequential
monitoring of large areas. Collaboration with soil scientists from USDA ARC; as
recommended by the NETL staff; will be established for final system testing
using theirs well characterized fields.This novel
system for stationary measurements was initially funded by the Cerbon Sequestration Research Program in the DOE Office
of Science. |
