CarbonNet Pelican 3D marine seismic survey

The CarbonNet Project conducted a marine seismic survey in Bass Strait in February 2018. The purpose of the survey was to gain deeper knowledge of the underlying geology of the area to help confirm the potential for geological carbon dioxide (CO2) storage. Preparation for the survey involved stakeholder consultation and regulatory and environmental approvals.

Carbon Capture and Storage (CCS) is being explored as part of a suite of solutions with the potential to mitigate greenhouse gas emissions and address climate change.

The Intergovernmental Panel on Climate Change believes that CCS can play an important role in helping to meet global emission reduction targets.

Survey method and equipment

Seismic surveying is commonly used in the resources industry to gain a better understanding of subsurface geology.

Marine seismic surveys are carried out by a specialised vessel towing a sound wave source that produces sound pulses in a controlled frequency range at set intervals.

The sound signals are reflected back by underground rock formations and are captured by hydrophones (acoustic receivers) in 'streamers' that are also towed by the vessel. The data collected by the hydrophones is recorded on board the vessel for later analysis and interpretation.

Location

The survey covered approximately 166 square kilometres offshore from Golden Beach (between Loch Sport and Seaspray), Gippsland.

The survey took place within the greenhouse gas assessment permits VIC-GIP-002 (in Commonwealth waters) and GGAP006386(V) (in Victorian waters) managed by CarbonNet.
