Project eNiGMA
Next Generation Maritime Archaeology
Project eNiGMA is an initiative of the Hellenic Archaeological Exploration Society to bring advanced underwater imaging, robotics, remote sensing, and three-dimensional documentation technologies to maritime archaeology.
By combining remotely operated vehicles (ROVs), sonar, underwater imaging, positioning systems, and high-resolution three-dimensional scanning, Project eNiGMA seeks to expand the ability of researchers to discover, document, measure, and monitor underwater environments.
The initial focus is underwater archaeology, but the same technologies have applications in marine geology, reef monitoring, environmental research, and other scientific investigations of the seafloor.
Extending the Researcher's Reach
ROVs as Platforms for Scientific Investigation
Human divers remain essential to underwater research, but diving imposes unavoidable limitations. Available bottom time decreases with depth while risk, decompression requirements, logistical complexity, and cost increase.
An appropriately equipped ROV can remain underwater for extended periods, operate beyond practical diving depths, repeatedly return to the same location, and carry multiple scientific sensors.
Depending on the research objective, an ROV can carry:
High-resolution cameras
Sonar
Underwater laser scanners
Positioning and navigation systems
Lighting and imaging equipment
Environmental and other scientific sensors
The objective is not to replace divers or researchers. It is to extend where they can work and what they can measure.
Underwater 3D Laser Scanning
Creating Measurable Digital Records
Photography and video document appearance. Underwater laser scanning adds measurable three-dimensional geometry. For archaeology, scanning can document shipwrecks, submerged settlements, ancient harbor structures, buildings, walls, machinery, cargo, and other cultural remains. For marine geology, it can document seabed morphology, rock formations, erosion, sediment movement, and other geological features. For reef and habitat research, three-dimensional surveys can document physical structure and establish measurable records of environmental conditions.
The objective is not simply to create a 3D model. It is to create data that can be measured, studied, and compared.
Document Change Over Time
Establish a Baseline. Return. Measure What Changed.
One of the greatest advantages of three-dimensional documentation is repeatability. A scan establishes a measurable baseline. Returning months or years later allows researchers to compare new data with the original survey.
This can help document deterioration of archaeological sites, sediment movement, erosion, storm damage, geological change, reef growth or loss, habitat changes, and other physical changes to underwater environments. The same approach can also provide a permanent digital record of sites that may themselves change or deteriorate.
A scan captures a moment. Repeated scans document change.
Support Project eNiGMA
HAES welcomes collaboration with universities, archaeological authorities, marine scientists, engineers, ROV specialists, technology companies, equipment manufacturers, and other organizations interested in advancing underwater research.
Support can include equipment, technical expertise, research collaboration, field opportunities, sponsorship, or financial contributions.
