Conclusions

• Site data required at an early stage
• Geophysical survey should incorporate

• Bathymetry Echosounder
• Seabed Features Sidescan Sonar
• Shallow Geology Sub-bottom Profiler
• Debris Location Magnetometer

• Survey Data supports many other activities

• EIA
• Foundation Engineering
• Cable Engineering (Landing sites / Topographic
  survey)
• Benthic Survey Workscope
• Targeted Geotechnical Survey Workscope

• Targeted data acquisition leads to cost savings
