Mayberry Slough

Mayberry Slough  is a restored wetland on Sherman Island, near Antioch.  It was established in 2010 by the CA Department of Water Resources.  We are measuring eddy covariance fluxes of carbon dioxide, water vapor and methane with the eddy covariance method. And, this site has the longest data record among our wetland sites.

 The site experiences much year to year variability due to its position near the confluence of the San Francisco Bay Estuary and the Sacramento and San Joaquin Rivers.  Hence, there is appreciable year to year differences in salinity at this locale. A summary of findings from 14 years of observations is in Delwiche et al. 2025:
