Short summary
This study demonstrated the response of organic soils in the Arctic tundra to freeze–thaw cycles (FTCs), focusing on the quantitative and qualitative characteristics of dissolved organic carbon (DOC). The highlights found in this study are as follows: (i) FTCs altered DOC properties without decreasing soil microbial activities, and (ii) soil aggregate distribution influenced by FTCs changed DOC characteristics by enhancing microbial activities and altering specific-sized soil pore proportion.
