Quantifying Carbon Turnover and Microbial Decomposition Rates in Arctic Subsea Permafrost Environments
This study estimates the carbon storage capacity of Arctic shelf permafrost, finding that while stocks are large, microbial decomposition rates are constrained by cold, saline conditions.
What are the primary environmental constraints limiting microbial decomposition of organic carbon in Arctic subsea permafrost?
Knowledge gap
What remains worth asking
The sensitivity of subsea permafrost carbon pools to climate-induced thaw remains poorly constrained in global carbon cycle models.
Potential contribution
Why it may matter
Refines global carbon budget estimates by clarifying the role of subsea permafrost as a long-term carbon sink.
