USGS National Wetlands Research Center: Accretion, Subsidence, and Sea-level Rise
Surface accretionary processes are measured from artificial marker horizons. To minimize disruption of these horizons during coring, we use a cryogenic coring apparatus that freezes the marsh ... and the bottom of the pipe. The difference in rates between the SET and the marker horizon provides an estimate of the rate of subsurface processes or what we call ...
