Community composition of ammonia oxidizing bacteria in Barataria and Terrebonne Bays in 2015 and 2016

This dataset contains relative abundances (%) of terminal restriction fragments of the ammonia monooxygenase genes (amoA) from ammonia-oxidizing bacteria (AOB) 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 Terminal Restriction Fragment Length Polymorphism (TRFLP) of the amoA genes. Samples were collected in July 2015 and July 2016.本数据集包含采自美国路易斯安那州Terrebonne湾（TB）、Barataria湾西部（WB）及Barataria湾东部（EB）的12处湿地中，氨氧化细菌（ammonia-oxidizing bacteria, AOB）的氨单加氧酶基因（ammonia monooxygenase genes, amoA）末端限制性片段的相对丰度（单位：%）。各研究区域均设置2处受油湿地与2处未受油湿地作为采样点；在每处湿地中，研究人员从湿地边缘沿20米样带采集5厘米深的土壤岩芯，并每隔5米采集一份土壤样品。所有样品均通过末端限制性片段长度多态性（Terminal Restriction Fragment Length Polymorphism, TRFLP）技术针对amoA基因进行分析。样品采集工作分别于2015年7月与2016年7月开展。
