Dispersant-Related Oil Spill Response Communication Tools: Toward an Enhanced Approach to Conveying Complex Topics in an Approachable Manner

Abstract

ABSTRACT During the response to the Macondo Well release in the Gulf of Mexico in 2010, it became evident fairly quickly that there was a potential disconnect between existing scientifically-based information relating to the use of oil spill dispersants and the information that was readily available to the general public, the media, and government officials. At best, both sets of information were aligned and provided a valuable perspective to those who sought an increased understanding of the workings of oil spill response tools. At worst, there was a large misalignment and the information that was available to the public did not accurately reflect the known science of what dispersants have been designed to achieve. In this latter case, conclusions about dispersant use may have been formed incorrectly, providing a backdrop upon which individuals were not able to develop an informed opinion regarding the use of dispersants. In the case where incomplete and potentially unbalanced information is used to inform the public, it is possible that negative effects will result, i.e., opinions may be formed based on fear of the unknown, causing a delayed or less than optimal decision making process. While it is recognized that decisions made during a spill response may be challenging and may involve an environmental trade-off, an informed public can be a valuable asset during the stages of an emergency response when the pros and cons of the specific response options are being debated. To assist with an informed dialog, it is important to have materials available that accurately reflect the scientific principles upon which they are based, but without requiring extensive study of their details for a general understanding of their primary assumptions and conclusions. This paper summarizes recent efforts to develop readily available materials that can provide a better understanding of the use of dispersants during an offshore oil spill response. These efforts have been focused on developing simple yet effective tools which describe dispersants within the framework of an oil spill response tool box and the scenarios in which these tools may be used for the most positive environmental effect.
