Gene abundance of nitrifiers, denitrifiers, methane-oxidizers and total bacteria, nitrification rates, and sediment chemistry in four marshes on the East Coast of the United States, 2001-04-24 to 2017-06-28

This data set contains gene abundance data for six microbial genes (archaeal amoA, betaproteobacterial amoA, comammox amoA, nirS, pmoA, and bacterial 16S rRNA) collected from salt marsh sediment in four areas on the eastern coast of the United States (Barn Island Wildlife Management Area, Connecticut; Cottrell Marsh, Connecticut; Plum Island Estuary, Massachusetts; Great Sippewissett Marsh, Massachusetts) between 2001 to 2017. Potential nitrification rates are provided for Barn Island and Plum Island, while various sediment chemistries are provided for all four locations (see Methods for details).
