Temporal effects of oiling and plant type on microbial biodiversity and predicted metabolic function in marine sediments: A mesocosm study in April/September 2016

Sediments were collected for a mesocosm project to examine the overall response of microbial diversity to oil exposure, plant type, and also to characterize bacterial communities associated nitrogen and sulfur cycling processes in marine sediments. Sediments samples were collected from control and amended mesocosms set up at Dauphin Island Sea Lab that consisted of the black mangrove, Avicennia germinans, along with either a monoculture or polyculture of the smooth cord grass, Spartina alterniflora. Data were collected in triplicates from control and amended mesocosms at three time points, before treatment in September 2015, 6 months after treatment in April 2016, and 11 months after treatment in September 2016. Additional data from this mesocosm study can be found in GRIIDC datasets R4.x262.000:0026 and R4.x262.000:0034.

本研究为探明微生物多样性对石油暴露、植物类型的整体响应，并表征海洋沉积物中与氮硫循环过程相关的细菌群落，为一项中型生态系统（mesocosm）实验采集沉积物样本。沉积物样本采集自设于多尔芬岛海洋实验室（Dauphin Island Sea Lab）的对照组与处理组中型生态系统，实验群落包含黑红树（Avicennia germinans），以及单一种植或混植的互花米草（Spartina alterniflora）。研究于三个时间节点设置三份重复采集样本：2015年9月处理前、2016年4月（处理后6个月）以及2016年9月（处理后11个月）。该中型生态系统研究的额外数据可从GRIIDC数据集R4.x262.000:0026与R4.x262.000:0034中获取。
