New paper finds large geologic source of CO2 emissions that may confound carbon cycle estimates — Published in the Journal of Geophysical Research
Study finds degassing of 'relatively large CO2 emissions' from geologic sources occurs through soils, groundwater and local thermal springs in tectonically active regions. The authors measured CO2 emissions up to 6.3 times greater than in 'a comparable site that was some distance from fault sites.' According to the authors, such 'Geologic carbon sources may confound ecosystem carbon balance estimates.'
