Responding to future oil spills: lessons learned from Deepwater Horizon

tracking and forecasting surface oil, protecting coastal and oceanic wildlife and habitat, managing fisheries and protecting the safety of seafood. The papers describe the process underway to determine the impact of the spill on the natural resources and ecosystems of the Gulf of Mexico, but because those analyses are not completed, no conclusions are presented. The remaining 12 papers have been previously published online.

“While the federal family was well versed in oil response and remediation, and we brought many resources to bear, the scale and complexity of Deepwater Horizon taxed our organizations in unprecedented ways,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator.

“We learned much during this extraordinary disaster and we hope the lessons learned will be implemented before and used during any future events.”

In one of the papers — “Science in support of the Deepwater Horizon response” — lead author Lubchenco and her co-authors suggest future oil spill response preparedness include:

  • Gather adequate environmental baselines for all regions at risk;
  • Develop new technologies for rapid precise reconnaissance and sampling to support a timely and robust response effort;
  • Fill large information gaps regarding biological effects of oil, changing climate, and other simultaneous drivers of variability in coastal and aquatic ecosystems;
  • Require future oil extraction permits be conditional on having mechanisms in place to rapidly assess flow rate; and
  • Conduct research on the impacts of dispersants and dispersants-plus-oil on a wide range of species and life stages.

Another paper — “Application of science and engineering to quantify and control the Deepwater Horizon oil spill” — describes the unprecedented collaboration among government, academic, and industry scientists and engineers. Lead author Marcia McNutt, Ph.D., director of the USGS, explains how scientific and engineering information was crucial to guide decision-making for questions never before encountered, especially during the tense hours after the well was capped, but might still be leaking underground.

Although we all hope ‘Never again!’ will there be an oil spill like the Deepwater Horizon, there will always be some risk as we move into deeper water and more difficult environments in our quest for the planet’s remaining fossil fuels,” said McNutt. “A significant drawback in addressing many of the issues we confronted in Deepwater Horizon was the lack of peer-reviewed scientific publications from prior marine-well blowouts to help guide our actions; we will not make that mistake again by neglecting to publish for posterity the scientific lessons from this tragedy.”

The event also showed the value of federal partnerships with academic institutions.

“The coordination within and across agencies was impressive, but so too was the engagement of academic scientists in a joint effort to respond to the disaster” said Steve Murawski, a co-author on both introductory papers, chief scientist at NOAA Fisheries during the response effort and now a professor at the University of South Florida. “Through these partnerships, new scientific discoveries were made such as estimating flow rate from atmospheric measurements, testing for dispersant in seafood, understanding the behavior of the loop current, and discovering novel microbial communities in the Gulf.”

A final paper — “Scientific basis for safely shutting in the Macondo well after the April 20, 2010 Deepwater Horizon blowout” — further points to the unprecedented level of coordination among scientists, engineers, and emergency response officials in the public and private sectors.  In this paper, scientists describe the geological hazards of shutting in the well and the conditions under which this could safely and successfully be done.

“Without this level of cooperation and round-the-clock engagement by people from many disciplines, it would not have been possible to carry out the continual scientific analyses needed to ensure the well was not leaking below the sea floor once the capping stack was closed,” explained lead author Steve Hickman, USGS research geologist. “For the government scientists onsite at BP headquarters, rapid acquisition and analysis of critical data sets and open exchange of ideas and possible outcomes was essential to ensuring the well had enough integrity to remain safely shut in until it was killed and sealed with cement.”
