Investigating the recent massive oil spill in the Gulf of Mexico is a tall order. There are many contributing causes and a multitude of creative solutions are going to be needed to restore the environment.
During any investigation of this magnitude, there are guaranteed to be a few surprises. And the Deep Horizon oil spill is no exception.
Scientists have discovered a previously unknown type of oil-eating bacteria feasting on oil from the spill.
This microbe is unique from previously studied varieties because it doesn’t consume large quantities of oxygen along with the oil. Oxygen consumption is a concern because oxygen is needed in the sea to support life.
This microbe also thrives in cold water temperatures associated with the deep ocean, which might explain why it hasn’t been seen before. Some scientists are theorizing that the microbe adapted in the deep ocean to consume the oil that naturally seeped from the ocean floor. Since the huge influx of oil to the water, the bacteria populations have exploded.
Scientists are in a disagreement over how much oil remains in the Gulf, but there is no doubt that less is better.
This serendipitous solution is a welcome addition to the clean up efforts. Obviously, there are many other solutions that will needed, but anything that safely reduces the overall amount of oil is a positive development. Hopefully, with some additional research this microbe could be a potential solution to future incidents.
When performing an investigation, the unexpected sometimes happens. The better understood the problem is, the easier it is to adapt to any new information. The Cause Mapping method of root cause analysis is an effective way to organize all information needed during an investigation. Clearly understanding the causes that contribute to an incident will allow an organization to adapt as new information comes available and make sure that resources are used in the most efficient ways when implementing solutions.
