Maritime Archaeology

Goodwin & Associates has a leading maritime archaeology department experienced in investigating submerged cultural resources. We were the first cultural resource management firm certified as an Organizational Member of the American Academy of Underwater Sciences (AAUS).

Aided by the latest technology, our archaeological divers conduct in-depth surveys of submerged historic sites (i.e., shipwrecks and inundated terrestrial sites). We use remote sensing geophysical survey, remotely operated vehicles (ROVs), to locate, document and map potentially significant cultural resources. Our Geomatics Division works in parallel to produce highly accurate map products, visualizations and graphics.

Safety is our priority, and we are proud of our zero-incident rate during archaeological diving operations.

Our maritime archaeologists and geographic information specialists are ready to support clients with their maritime exploration needs.
