ABSTRACT
Scleractinian corals, primarily plate corals in families Agaricidae and Acroporidae, were monitored in situ before, during and after a 3D marine seismic survey. An initial four day seismic run, resulting in a maximum 24â¯h received sound exposure level (SEL24) of 204â¯dB re 1⯵Pa2·s and received 0-to-peak pressure (PK Pressure) of 226â¯dB re 1⯵Pa, had no detectable effect on soft tissues or skeletal integrity. Subsequently, a full marine seismic survey (Maxima 3D MSS), proceeded over two months and included seismic acquisition lines at 240â¯m spacing over the broader reef lagoon (South Scott Reef), generating maximum received SEL24 of 197â¯dB re 1⯵Pa2·s and received PK Pressure of 220â¯dB re 1⯵Pa at the coral monitoring sites. The analysis detected no effect of seismic activity measured as coral mortality, skeletal damage or visible signs of stress immediately after and up to four months following the 3D marine seismic survey.
