Summary
Habitat biogeochemistry was assessed by measuring 31 variables in sediments, porewater, and surface waters related to mercury content, organic matter, sediment characteristics, and microbial rates of sulfate reduction, iron reduction, and methanogenesis. Fifty-six composite surface (0-2 cm) sediment cores and 32 surface water samples were collected in three wetlands in the spring and summer of 2005 and 2006.

Data were collected to better understand spatial variation in MeHg production and availability and the effects of habitat biogeochemistry, food web structure, and diet composition on MeHg bioaccumulation in the wetland-obligate California black rail (Laterallus jamaicensis coturniculus).
