Abundance of ammonia oxidizers and methane oxidizers in Avicennia and Spartina plots in a Louisiana salt marsh three years after the Deepwater Horizon oil spill (2013)

This dataset contains values for abundances of ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and methane-oxdizing bacteria (MOB) collected from 4 sites in western Barataria Bay (WB), LA, in June 2013. Two sites were oiled and two sites were unoiled. At each site, we collected 5-cm deep soil cores from 4 plots dominated by Avicennia geminans and 4 plots dominated by Spartina alterniflora. Each sample was analyzed for abundance of AOB (betaproteobacterial amoA genes), AOA (archaeal amoA genes), and MOB (pmoA genes).

本数据集包含2013年6月采自路易斯安那州（LA）巴拉塔里亚湾西部（western Barataria Bay, WB）4个采样点的氨氧化细菌（ammonia-oxidizing bacteria, AOB）、氨氧化古菌（ammonia-oxidizing archaea, AOA）以及甲烷氧化细菌（methane-oxidizing bacteria, MOB）的丰度数据。其中2个采样点受石油污染，其余2个采样点未受石油污染。在每个采样点，研究人员分别从4个以海榄雌（Avicennia geminans）为优势种的样地，以及4个以互花米草（Spartina alterniflora）为优势种的样地中，采集了5 cm深的土壤柱芯。所有样品均针对AOB（β-变形菌门amoA基因）、AOA（古菌amoA基因）以及MOB（pmoA基因）的丰度进行了分析检测。
