    dct:description "Habitat biogeochemistry was assessed by measuring 26 variables in sediments and porewater related to mercury content, organic matter, sediment characteristics, and microbial rates of sulfate reduction, iron reduction, and methanogenesis. Thirty-six composite surface (0-2 cm) sediment cores were collected in each of three wetlands in the spring and summer of 2005 and 2006." ;
