Microbial communities of beaches of the Baffin Island Oil Spill (BIOS) Project almost 40 years later. oil metagenome

This project re-visited beaches of the 1980s Baffin Island Oil Spill (BIOS) Project in 2019, almost 40 years after the original project. Sediment samples were collected from both the previously oil-exposed beach test plots and nearby control sites to characterize the corresponding microbial communities. The goals of this project were to: (i) assess any long-term legacy effects of the 1980s oil exposure, (ii) compare the microbial communities between the different oil-exposed beach sites, and (iii) identify potential oil-degrading microorganisms that may have been enriched since the original oil exposure.

本研究于2019年重访了1980年代巴芬岛溢油（Baffin Island Oil Spill, BIOS）项目的海滩区域，距该项目最初启动已近40年。研究人员从此前曾受溢油暴露的海滩试验样地及邻近对照点位采集沉积物样本，以表征相应的微生物群落特征。本项目的研究目标如下：(i) 评估1980年代溢油暴露是否存在长期遗留效应；(ii) 对比不同溢油污染海滩样地的微生物群落差异；(iii) 筛选可能自初始溢油暴露后发生富集的潜在石油降解微生物。
