The purpose of this study was to examine the impact of social media on crisis communication. To evaluate this impact, a case study method was utilized examining the crisis communication response of the Deepwater Horizon Oil Spill on April 20, 2010. This study focused on the response of the responsible party, British Petroleum, and the general public over three social media: Facebook, Twitter, and blogs. Through extensive analysis of both the company's and public response to the Gulf spill, nine implications were identified regarding social media's influence on crisis communication. These implications highlighted the potential for organizations to build interpersonal relationships with its publics. These relationships were found to be crucial in times of crises. The implications of this study also pointed to interactivity, using a "human voice," trust, and credibility as crucial factors in building these relationships and leading an effective crisis response across social media. This study also noted the new stress for organization's to respond quickly to crises as a result of instant news brought by social media. Implications of this study also highlighted social media's influence on individuals becoming contributing members of a crisis response. While social media has influenced the practice of crisis communication in many ways, this study found that the principles and ethics of the field have remained the same. In conclusion, analysis suggests that BP neglected using social media in its crisis response, a channel which has entered the mainstream of crisis communication. As a result, this study recommends the use of social media before, during, and after a crisis to ensure the welfare of a company and its relationship with its publics.

Within two months of its emergence, the BP Gulf Oil spill had become the worst environmental disaster in United States history. However, for those studying public relations the oil spill brought more than ecological disaster, by providing a case study of crisis communication. Although there were a number of crisis responses from BP throughout the course of the oil spill, the primary crisis response crafted by BP was an image restoration campaign which premiered in early June 2010. This campaign, though it exhibits qualities of a standard crisis response, was wildly unpopular with the United States Government and citizenry. This rhetorical analysis attempts to uncover the reasons behind the campaign's failure through an application of the genre model of criticism. By defining the crisis communication genre and applying it to the artifact, the current study uncovers the reasons behind the failure of the campaign. Through this discussion, this analysis identifies that BP did not address all necessary exigencies, nor did it consider the influence a rhetor can have on a message. An explanation for the failure of BP' s campaign provided a plethora of implications to the fields of public . relations and rhetorical criticism, while beginning a discussion to help define the crisis communication genre.

The explosion of the Deepwater Horizon oil platform on April 20, 2010 resulted in the second largest oil spill in history. In this study, the distribution and chemical composition of hydrocarbons within a 45 km radius of the blowout was investigated. A complete set of hydrocarbon data were acquired from the National Oceanic and Atmospheric Administration (NOAA) and from BP, including data from 16 research missions collected over eight weeks. The distribution of hydrocarbons was found to be more dispersed over a wider area in subsurface waters than previously predicted or reported. Several hydrocarbon plumes were identified including a near-surface plume (0.5 to 50 m), two small mid-depth plume (240 to 290 m and 850 to 880 m), and a large deepwater plume approximately 1,050 to 1,300 m below surface. Water soluble compounds were preferentially extracted from the rising oil in deepwater, and were found at potentially toxic levels both in and outside of areas previously reported to contain the majority of hydrocarbons. Data collected from different research missions were measured for a wide variety of chemical compounds, but not every sample was analyzed for the same chemical compounds. To overcome the challenge of variability in sample data, a non-parametric method of evaluating the percentage of detectable results, was used for all data analysis in addition to evaluation of total sample concentrations. The two analysis techniques yielded similar results. This approach may be useful in other studies in which samples are measured for varying number of compounds and have varying detection limits. The distribution and toxicity of hydrocarbons in sediments between August and October, 2010 was also investigated and was found to be fairly localized.
