Bacterial and archaeal gene abundances in Barataria and Terrebonne Bays in 2015-2016

This dataset contains values for abundances of ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), methane-oxdizing bacteria (MOB), and denitrifying bacteria (DNB) collected from 12 marshes in Terrebonne Bay (TB), western Barataria Bay (WB), and eastern Barataria Bay (EB), LA. In each region, we sampled two oiled marshes and two unoiled marshes. At each marsh, we collected 5-cm deep soil cores along a 20-m transect from the marsh edge and collecting soil samples every 5 m. Each sample was analyzed by quantitative PCR for abundance of AOB (betaproteobacterial amoA genes), AOA (archaeal amoA genes), MOB (pmoA genes), and DNB (nirS genes). Samples were collected in July 2015 and July 2016.
