| contents | We aimed to study the effect of hydrological conditions on carbon mineralization during the degradation process of a Palsa. We simulated the processes of a Palsa degradation by incubating 1m soil cores from a Palsa and the surrounding Peatland under several water treatments. Each water treatment had three replicates, for a total of 15 cores. We continuously measured CO2 and CH4 emissions for 90 days by using a Picarro analyzer. Initially, we thawed the first 60 cm of the core and then deepened the thawing depth by 20 cm every four weeks to assess the contribution of deeper soil layers to C emissions . The results show higher CO2 emission rates following the thawing events for all the treatments under flooded conditions. |
