Summary
This factsheet explains marine seismic surveying using compressed-air acoustic sources and hydrophone streamers, distinguishing 2D, 3D and repeated 4D methods. It outlines potential effects on marine species, environmental assessment and possible acoustic mitigation measures, alongside NOPSEMA’s assessment of environment plans before proposed surveys can proceed.
