Introduction
  • Purpose Review of the OGP JIP Sound and Marine
    Life
  • to the Arctic Study Tour, 14. October 2008
  • Content
  • - The marine sound issue
  • - Current mitigation measures
  • - Scope of JIP Phase II
  • - JIP Phase II research categories / projects
  • - Ongoing JIP Phase III discussions

Possible effects of industry sound on animals
  • Mortality
  • Temporary (TTS) or permanent (PTS) hearing loss
  • Interference which can lead to damaging
    behavioral changes in feeding, mating, shoaling,
    migration, etc.
  • Interference with animal sonar or long-distance
    communication
  • Undesirable effects on fishing and indigenous
    subsistence hunting
  • Undesirable effects at other levels of the
    ecosystem including planktonic organisms and
    juvenile stages

Result lack of scientific data hampers risk
assessment, causes permitting delays, increased
environmental opposition, increased operational
costs and potential safety risks

Current Mitigation Examples
  • Pre-survey planning
  • Visual monitoring visual observers monitor a
    pre-determined radius around the source vessel
    for at least 30 minutes prior to initiating
    soft-start procedure
  • Soft-start smallest airgun in terms of energy
    output and volume is activated first, additional
    airguns gradually added over a 20-40 minute
    period
  • Exclusion zones range from 500m-1500m must be
    clear of specific animals before soft-start may
    commence energy sources must be shut-down if
    animal enters zone (except UK)
  • Licence Conditions which exclude seismic during
    fish spawning periods
  • Seasonal restrictions
  • Within the last year, Australia, Brazil, Canada,
    Ireland, U.K. and U.S.A have introduced, revised
    or are reviewing guidelines resulting in
  • Direct and Indirect risks to resource access
  • Risk of not being able to conduct operations in
    low visibility
  • Increased survey expense
  • Increased survey duration
  • Investment in mitigation technologies /
    methodologies
  • Increased safety risks

Sound and Marine Life JIPProgramme Objectives
The Purpose of the JIP on Sound and Marine Life
is to promote peer-reviewed research which allows
Industry to
  • Understand / define the environmental risks of
    offshore operations
  • Reduce regulatory uncertainty by providing
    scientific data
  • Develop cost effective, credible mitigation
    measures
  • Improve efficiency of planning offshore project
    development

JIP Phase 2
  • Category 1 Sound Source Characterization and
    Propagation
  • Better define the output from EP industry
    sources and how the sound propagates
  • Category 2 Physical, Physiological, and Hearing
    Effects
  • Characterize the physical and physiological
    effects of sound on target marine life, gain
  • understanding on what and how animals hear, and
    how exposure affects hearing ability
  • Category 3 Behavioural Reactions of Marine Life
    and Biological Significance
  • Better understand behavioural responses of marine
    life to industry sound sources, and
  • The biological significance of these exposures
  • Category 4 Mitigation, Monitoring, Analysis
    Management of Monitoring Data
  • Reduce exposure of animals, thereby allowing
    industry to operate more effectively in
  • areas which are subject to sensitivity
    restrictions and low light/visibility conditions
  • Category 5 Research Tools
  • Includes development of satellite tags,
    autonomous bouys and other tools that enable
  • Us to conduct research in other categories

Common error in the understanding of Geophysical
Principles.
The figure to the right is said to show an airgun
pulse recorded by a sonobuoy at 39 km distance.
Since the sound travel faster through the
bedrock than through water, it is obvious that
the bedrock signal should arrive first. At a
distance of 39 km the energy that has traveled
through water will be strongly attenuated

Potential Future Research
  • Additional source measurements to properly and
    fully characterize EP sources
  • Effectiveness limitations of propagation models
  • Alternative sources to air guns for seismic
    acquisition
  • Mitigation and monitoring tools and methods e.g.,
    PAM, underwater gliders, Unmanned Aerial Systems
    (UAS), Active Acoustic Monitoring (AAM) methods
  • Distribution/abundance and behavioural analysis
  • MMO database implementation
  • Studies on ringed seals because it is thought
    that seals experience TTS at lower exposures
  • Mysticete, baleen and beaked whale hearing.
  • Stapedial reflex, and whether it protects against
    unanticipated sound
  • Fish and turtle research
  • Animal responses to specific marine vibroseis
    transducers
  • Investigation of new methods for measuring
    long-term and cumulative effects of sound plus
    non-acoustic stressors in the marine environment

OGP JIP Sound and Marine LifeConclusions
  • A significant research program is undertaken, and
    results are coming in during the next few years
  • All aspects of EP activities creating sound has
    been addressed, but seismic surveys has been
    given most attention in Phase II.
  • 59 projects are included in the program, some
    already completed.
  • A Program Review Meeting will take place in
    Houston, October 28 30, 2008.
  • Possible 3 year extension (2009 2012) of the
    JIP will be decided later this year.

Thank you for your attention.
