Abundance of ammonia oxidizers, methane oxidizers and denitrifiers in Louisiana salt marshes four years after the Deepwater Horizon oil spill (2014)

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 Port Sulphur in eastern Barataria Bay (PS), LA in July 2014. 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 for abundance of AOB (betaproteobacterial amoA genes), AOA (archaeal amoA genes), MOB (pmoA genes) and DNB (nirS genes).

本数据集包含氨氧化细菌（ammonia-oxidizing bacteria, AOB）、氨氧化古菌（ammonia-oxidizing archaea, AOA）、甲烷氧化细菌（methane-oxidizing bacteria, MOB）与反硝化细菌（denitrifying bacteria, DNB）的丰度数据。所有数据采集于2014年7月，采自美国路易斯安那州特尔博恩湾（Terrebonne Bay, TB）、西巴拉塔里亚湾（western Barataria Bay, WB）以及东巴拉塔里亚湾硫磺港（Port Sulphur in eastern Barataria Bay, PS）的12处滨海湿地。每个区域均选取2个受石油污染湿地及2个未受石油污染湿地作为采样样地；在每处湿地中，沿距湿地边缘20米的样带，以每5米的间隔采集5厘米深的土壤岩芯，并获取对应土壤样品。所有样品均针对AOB（β-变形菌amoA基因）、AOA（古菌amoA基因）、MOB（pmoA基因）以及DNB（nirS基因）的丰度开展了检测分析。
