Table 1 Environmental conditions across our inundation treatments from the least inundated (SL-40) to the most inundated (SLR100)

From: Salt marsh litter decomposition varies more by litter type than by extent of sea-level inundation

  1. SLI is the mean altitude of our site. SLR30 is the simulated SLR under SSP1−2.6. SLI60 is the simulated SLR under SSP3-7. SLR100 is the simulated SLR above predictions, and SL-40 represents a lower level of inundation than the mean inundation of our site. Please see Methods section for more information.
  2. ameasured on four random dates across all mesocosms and measured as volumetric water content in a cylinder of sediment of 3 cm in diameter and 6 cm in length, n = 100.
  3. bmeasured at the marsh organ between May 4, 2021 and October 20, 2021. h d-1 is hour per day.
