Investigation of TELLUS data to produce peat depth models for NI and its application to carbon stocks

Under the UN Framework Convention on Climate Change, the UK is committed to implementing policies that protect reservoirs of greenhouse gases. Soil carbon stores and changes are a major component of the required annual returns made by participating countries to the IPCC. The high proportion of soil carbon in peat (42% of soil C in NI) is explained by the relatively high carbon density of peat and peaty soils. Soil C density, the mass of organic C per unit area, is calculated using %C, depth and bulk density values. This research investigates the use of TELLUS gamma-radiation data to produce peat depth models for Northern Ireland and improve estimates of carbon stocks. Gamma-radiation from rocks is attenuated by overlying peat; previous tests show some correlation between gamma-radiation and peat depths to at least 2 m. We are using GIS to examine existing estimations of soil carbon stores. Peat depths from historical sources (1956) and recent surveys (1997/98) have been incorporated into GIS through georeferencing and digitisation. Visual outputs displaying average peat depths for individual 1km² grid squares have been compared with existing estimates. The spatial interpolation of peat-depth values for individual bogs has been completed. Current work is assessing the relationships between the TELLUS data and previous peat depth measurements using geostatistical techniques. Peat depth estimations made from TELLUS radiometric data will be crosschecked using geophysical methods. An improved peat depth model, produced through the integration of the TELLUS data and known peat depths, could improve carbon stock calculations.
