Thin-Layer Sediment Placement in Coastal Marshes Monitoring and Experimental Data

Data Resource
August 2020

Thin-layer placement (TLP) is an emergent climate adaptation strategy that mimics natural deposition processes in tidal marshes by adding a small amount of sediment on top of marsh in order to maintain elevation relative to sea level rise. A 2017-2020 collaborative research project at eight National Estuarine Research Reserves on the U.S. Atlantic and Pacific coasts conducted a coordinated field experiment to examine the effectiveness of TLP across diverse estuarine conditions including various regions, plant communities, and marsh elevations.

About these datasets

The project collected monitoring and experimental data of TLP treatments and reference plots in low and high marsh areas affected by sea level rise at each of the eight participating reserves. The project dataset description provides more detail about the three datasets generated by the project:

  1. Thin-layer placement field data
  2. Thin-layer placement sediment data
  3. Thin-layer placement porewater data
