Surface elevation table and marker horizon (SET-MH) plots were installed at multiple marshes along the Pacific coast beginning in 2012. They are used to measure millimeters of change in marsh...

SET-MH were installed in 2009 and 2010 with three replicates in Reference and Phase II and with two replicates (north-south) pairs in the 2009 restoration area (Units 1-4). SET-MH were read...
-
The surface elevation table (SET)-marker horizon (MH) approach (SET-MH, together) is a method for quantifying surface elevation change through measurements of surface and subsurface processes that...

Surface elevation tables with marker horizons (SET-MH) measure millimeter-scale changes in elevation over time. A combination of pin measurements (elevation change) and surface deposition...
-
Sediment accretion measurements were made at the SMARTX warming experiment at the Smithsonian Environmental Research Center's Global Change Research Wetland. Feldspar marker horizons were...

These data were collected as part of a cooperative study with the U.S. Army Corps of Engineers investigating deposition patterns within Raccourci Lake and Island, Louisiana. Samples of sediment...

Due to their position at the land-sea interface, coastal wetlands are sensitive to sea-level rise and many other aspects of global change. Small changes in coastal wetland surface elevation can...

This data set represents vertical accretion data from feldspar marker horizons in Rookery Bay National Estuarine Research Reserve and Ten Thousand Islands National Wildlife Refuge collected...
-
These data represent surface elevation change and vertical accretion time series collected from a series of degraded tidal wetland sites near Goodland, Florida, USA. Surface elevation was measured...
-
Elevation change and surface deposition are important drivers of salt marsh ecological processes and represent two of the fundamental variables for determining marsh resilience to sea-level rise....

Short-term carbon accumulation rates were examined by collecting 10-cm deep soil cores at 24 sites located in marshes spanning the salinity gradient in coastal Louisiana. Percent moisture, bulk...
