Marine Environment Guidance during Geophysical Operations

Abstract

Abstract The International Association of Geophysical Contractors (IAGC) has several subcommittees and workgroups focusing on specific subject areas in order to achieve its overall mission, which includes promoting the conduct of the geophysical industry's business in a professional, safe, and environmentally responsible manner. In 2011, the Association's Sound & Marine Life Workgroup completed an updated version of its Recommended Mitigation Measures for Cetaceans during Geophysical Operations (IAGC 2011a). Several documents have been developed to complement these recommended measures. Among these are the IAGC Recommended Visual Observer Reporting Forms (IAGC 2011b). Numerous countries require the use of visual observers who are responsible for monitoring the presence of marine mammals within defined zones during geophysical operations and implementing procedures to mitigate potential impacts. Various reporting forms have been developed for these observations. IAGC members identified a need to have a standard set of forms that could be used on a global basis to collect and report visual observer data, unless a country stipulates the use of different forms. In addition to streamlining the process for geophysical companies, the use of standardized forms encourages the collection of visual observation data in a consistent manner that facilitates meaningful analysis. A centralized database is being considered for collecting the data, further facilitating objective scientific research on the topic. IAGC has also prepared and published the document Guidance for Marine Life Visual Observers (IAGC 2011c), intended for use by third party visual monitoring personnel such as marine mammal observers (MMOs) or marine wildlife observers (MWOs) operating onboard vessels conducting marine seismic surveys. The document explains the role and responsibilities of the MMO/MWO, the role and responsibilities of the permit-holder and seismic contractor company, lines of communication between all onboard and information on reporting, conflict management, health, safety and environment (HSE) aspects and standards of conduct. These publications are examples of initiatives by IAGC, often working in partnership with other organizations, to minimize potential environmental impacts of geophysical operations and demonstrate the commitment of its members to working responsibly.
