Thick tephra deposition reduces the carbon sequestration capacity of peatlands

Key Points

• Carbon sequestration in peatlands decreases significantly with thick tephra layers, impacting overall ecosystem health.
• Field measurements showed a reduction of carbon sequestration capacity by up to 30% in affected areas.
• Analysis of soil carbon data highlighted the negative effects of tephra deposition on carbon storage.
• These findings underscore the need for assessing volcanic impacts on peatland carbon dynamics.
