Heller et al 2012: CARBSTOR – A New Method Quantifying C-Storage and Evaluating C-Release Potentials of Specific Peatland
Theme I. Inventory, stratigraphy and conservation of mires and peatlands
Existing data, concerning carbon (C) budgets of peatland soils, vary significantly and often do not consider differences in peat quality and quantity. The new developed CARBSTOR tool takes these differences into account. A GIS-based mire type classification was developed to classify different peatland polygons into dominant hydrogenetic mire types (HGMT). By u-sing idealized soil profiles, classified HGMT can be combined with typical amounts of stored C and potential C loss. These amounts were determined by own laboratory work and data analyses. CARBSTOR provides an innovative, helpful tool to estimate amounts of stored C and potential C-release of specific peatland landscapes.
