Overview

Modeling reveals solute transport dynamics and carbon mineralization potential in permafrost, indicating climate impacts.

Key Points

  • DOC in the active layer near the permafrost table shows rapid transport upon thaw due to lateral flow.
  • Transport times vary significantly for different depths of DOC, influenced by thaw conditions and warming scenarios.
  • Gradual warming leads to limited DOC mobilization, while abrupt warming causes faster lateral transport rates.
  • High liquid saturation during DOC transport may inhibit its mineralization into CO2 before export.
