Soil core metrics taken at Space for Time plots across the PIE LTER.

Soil cores were collected and evaluated at three different depth intervals for bulk density, organic matter by loss on ignition (LOI), pore water ammonium, and pore water salinity. These biotic and abiotic factors differ across marsh types and elevations and help to parameterize other measurements of marsh structure and function, as well as provide insight into marsh heterogeneity within a single site.
