Sherman Island Pasture

This site was our first venue in studying methane and carbon dioxide fluxes over peatland soils in the Delta. The site was chosen due to its long fetch and access to an AC power pole so we could run the power hungry pump for the LGR closed path tunable diode laser spectrometer to measure methane.   The site was grazed pasture infested with pepper weed.  Water tables moved up and down with irrigation and rain.

The site was in operation between 2007 and 2016. After it was converted to a restored wetland, US-Sne

The site is upwind of the Antioch Bridge and across the river from the PGE power plant, near Marsh Landing where Evo Baldocchi was born and reared.

Our first investigation into the nuances of this site are reported in the following paper
