MOSCOW, Idaho – Gauging long-term impacts of the Deepwater Horizon oil spill is the focus of an inter-disciplinary Strategic Sciences Working Group led by Science Advisor to the Director of the National Park Service Gary Machlis, a professor in University of Idaho College of Natural Resources.

Machlis will lead the group in developing and applying an innovative scenario-building technique to assist the environmental and economic recovery from the Gulf of Mexico oil spill. The group’s first session was based at the Incident Command Center in Mobile, Ala. College of Natural Resources graduate student Rachel Woita and postdoctoral researcher Jan Eitel assisted Machlis in conducting the scenario-building sessions.

“We are treating the ecology, economy and people impacted by the spill as a tightly coupled system,” said Machlis. “Our challenge has been to understand what is happening and what might happen from that broad perspective, and convert that understanding to scenarios that decisionmakers can use.”

“Dr. Machlis' work exemplifies the globally connected engagement we should expect of a 21st-century land-grant university,” said Duane Nellis, University of Idaho president. “We commend his leadership of an interdisciplinary team seeking to curb the consequences of this oil spill challenge.”

The first results of the working group are highlighted in an article published in the Aug. 27 issue of Science, entitled “Scenario-Building for the Mississippi Canyon 252/Deepwater Horizon Oil Spill.” Machlis co-authored the essay with Marcia McNutt, director of the U.S. Geological Survey. It is available online at www.sciencemag.org/cgi/content/full/329/5995/1018.

Their article describes how the group constructed scenarios that may help identify possible policies and actions to reduce negative impacts of the spill and speed up and sustain the recovery process. Each element of the scenarios was assigned a level of scientific uncertainty based on current knowledge.

One scenario in the Science article examined how long-term decline of plants, particularly in wetlands, is a probable consequence of the spill, and if extensive, could impair both fisheries recovery and resistance to hurricane damage with further damage resulting from the re-release of sequestered oil. Other scenarios dealt with impacts on the oyster fishery, health issues of workers and impacts on the tourism industry.

Since its first meeting held in May 2010, the group has briefed the Mobile Unified Command, Secretary of the Interior Ken Salazar, Natural Resource Damage Assessment staff, and others involved in Gulf restoration and recovery. The group will reconvene in New Orleans in September and continue work through the fall. Their results will provide information useful to decision makers, resource managers and other professionals developing and managing the existing response plans. All efforts by this working group are funded by the U.S. Geological Survey and the National Park Service.
