Data to support surface elevation change and vertical accretion data to support assessment of hummock formation/loss in tidal freshwater forested wetlands along the U.S. Atlantic coast (2009-2021)

This study evaluated surface elevation change and vertical accretion of sediments in hollows and on top of hummocks associated with the base of tree stems in tidal freshwater forested wetlands. Sites were along a gradient of habitat change from freshwater forest to marsh and tracked hollow subsidence and in-filling with transgression over 6 (Virginia) to 12 (South Carolina/Georgia) years. Both deep and shallow Surface Elevation Tables (SETs) were used and compared with accretion of surficial sediments during overlapping assessment periods.
