Marine Gravimetry Campaign

New Zealand (April / Mai / June 2011)
Client: Petrobras
Vessel: M/V "Orient Explorer" (Russia)

  • 6800 line Km
  • very heavy weather conditions
  • 980 crossing points
  • largest absolute value of differences in crossing points: 1.86 mGal
  • mean value of differences: 0.001 mGal
  • standard deviation: 0.74 mGal

The scientific aim of the marine survey was to collect geophysical data (2D seismic, gravity and magnetic) in the territorial water of New Zealand offshore East Cape. The Gravity data assisted the understanding of the petroleum prospectivity, the geological setting and the environmental significance of the survey area.
