Arctic Microbial response to oil and Corexit

Dataset homepage

Citation

MGnify (2019). Arctic Microbial response to oil and Corexit. Sampling event dataset https://doi.org/10.15468/hw9eqg accessed via GBIF.org on 2019-12-10.

Description

The fate of oil and oil spill response chemicals in the Arctic is of critical importance as marine shipping and oil exploration are increasing due to receding sea ice cover. Using indigenous Arctic marine organisms in freshly collected seawater, we identified of bacterial taxa that increase in relative abundance in response to both oil and Corexit in Arctic seawater, suggesting that some taxa biodegrade components of both oil and dispersant. We then paried these microbial analyses with the chemical loss of oil and the surfactant components of Corexit 9500. These results allow for the first comparison between Arctic and temperate environments in regards to the fate of Corexit and the microbes involved in biodegrading dispersants and oil.
