Relationships between salinity and short-term soil carbon accumulation rates from marsh types across

This paper shows that although researchers found relatively little difference in the rates of this short-term accumulation across marsh types, as salinity in wetlands rises, the amount of organic carbon in soil that can accumulate as a buffer against relative sea level rise decreases. That also means freshening of certain wetlands with coastal restoration project such as sediment diversions being planned for the Mississippi River or even additional rainfall, can help wetlands regain some of this organic storage ability and perhaps give these areas a buffer against succumbing as quickly to higher water levels.
