Global CO (sub 2) emission from volcanic lakes
Geology (Boulder) (March 2011) 39 (3): 235-238


The global CO (sub 2) discharge from subaerial volcanism has been estimated at approximately 300 Mt yr (super -1) . However, estimates of CO (sub 2) emissions from volcanic lakes have not been considered. In order to improve this information, extensive research on CO (sub 2) emissions of volcanic lakes worldwide has been performed. The observed normalized average CO (sub 2) emission rates increase from alkaline (5.5 t km (super -2) d (super -1) ), to neutral (201.2 t km (super -2) d (super -1) ), to acid (614.2 t km (super -2) d (super -1) ) in volcanic lakes. Taking into account (1) normalized CO (sub 2) emission rates, (2) the number of volcanic lakes in the world ( approximately 769), and (3) the fraction and average areas of the investigated alkaline, neutral, and acid volcanic lakes, the estimated global CO (sub 2) emission from volcanic lakes is 117+ or -19 Mt yr (super -1) , with 94+ or -17 Mt yr (super -1) as deep-seated CO (sub 2) . This study highlights the importance of a revision of the actual global CO (sub 2) discharge from subaerial volcanism.
