Preserving the Past, Supporting the Future of Marine Development
At CMG, we specialize in offshore heritage and marine archaeological services that safeguard underwater cultural heritage while enabling responsible marine development. Whether you’re planning offshore energy projects, subsea infrastructure, or coastal construction, our experts help identify, assess, and manage heritage assets in full compliance with international and local regulations.
We collaborate with developers, government bodies, Indigenous communities, and cultural heritage professionals to deliver end-to-end archaeological services tailored to offshore environments:
Desk-Based Assessments (DBAs)
Comprehensive reviews of historical records and geophysical data to assess the likelihood of heritage assets in the project area.
Marine Geophysical Survey & Interpretation
Use of high-resolution sonar, magnetometers, and sub-bottom profilers to detect, map, and interpret submerged archaeological features.
ROV & Diver Investigations
Targeted inspections using Remotely Operated Vehicles and certified divers to document wrecks, submerged settlements, aircraft, and artifacts.
Heritage Impact Assessments
Expert evaluation of how offshore activities may affect cultural heritage, with clear mitigation or avoidance strategies.
Monitoring & Mitigation Services
On-site archaeological supervision during seabed works, including real-time monitoring and post-activity documentation.
Wreck & Site Documentation
Detailed recording, mapping, and 3D modeling of underwater cultural sites for research, archives, and public engagement.
The seafloor holds centuries of human history—sunken ships, ancient landscapes, lost settlements. These aren’t just artifacts; they are vital cultural links to our shared past. Protecting them is not only a regulatory obligation under laws like the UNESCO Convention on the Protection of the Underwater Cultural Heritage, but also a responsibility we share as global citizens.
CMG operates with strict adherence to local and international heritage protocols, including:
We partner with accredited maritime archaeologists, heritage specialists, and Traditional Owners to ensure respectful, informed, and legally compliant project outcomes.
