A seismic shift in engagement with the fishing industry? A case study of the Prion 3D marine seismic survey in Bass Strait

Abstract

The relationship between the oil and gas and commercial fishing industries could be described as strained and at times highly combative. The source of much of the conflict has been conjecture around the impacts of seismic surveys on the marine environment, and of course impacts to commercially targeted species. These relationships exacerbate the challenges for oil and gas proponents in progressing new exploration activities and the relevant environmental approvals. We provide an example of how genuine engagement and collaboration between the two industries, and their broader networks, can lead to a better understanding of the needs of each sector. In turn, this can lead to investment into research to address shortfall in knowledge around impact and technical advances to mitigate potential impacts. Directed research to address key knowledge gaps is a critical component for coexistence of industry in the marine domain. Investment in research that reduces uncertainty for all sectors is critical for future petroleum exploration and exploitation. Researcher studies undertaken during the Prion 3D marine seismic survey include: (1) whether novel seismic survey sources mitigate potential impacts to fisheries; (2) before after control impact (BACI) assessment and biomass studies of scallops; and (3) validation of sound modelling. We examine some of the key decisions taken during the Prion 3D marine seismic survey development process and discuss how these were taken and how things may have otherwise ended without genuine engagement by both parties.
