Project Summaries

Below are summaries for the different phases of this project to apply new tools toward searching for shipwrecks in Thunder Bay National Marine Sanctuary.

 

Final Summary

Final Summary: Two Historic Shipwrecks Discovered in Thunder Bay National Marine Sanctuary

On May 23, 2017, researchers from NOAA’s Thunder Bay National Marine Sanctuary, NOAA’s Great Lakes Environmental Research Lab, and the University of Delaware discovered two shipwrecks during the second phase of this research project.

Phase IV

Phase IV: Divers Down! Using Digital Imagery to Photogrammetrically Model Deep Shipwrecks

Photogrammetric modeling has become a nearly ubiquitous tool used by researchers to rapidly document submerged archaeological sites. Driven mainly by advances in photo modeling software programs, the technique involves rendering many, overlapping photographs into a single, 3D digital model.

Phase III

Phase III: “Mission Executed”: Using Autonomous Technology to Rapidly Survey Historical Shipwreck Sites

Researchers used a technological solution to the challenge of getting a powerful sonar close enough to scan a large historic vessel in deep water: Autonomous Underwater Vehicles, or AUVs.

Phase II

Phase II: Deep Water Survey: Exploring Large Tracts of Lake Huron with Sound

Researchers used a wide-reaching sonar to scan large portions of the lake floor. By surveying large areas as quickly as possible, previously unexplored areas could be covered and new discoveries made.

Phase I

Phase I: Surveying the Bottom of Lake Huron from the Air Above

During the first project phase, researchers used Unmanned Aerial Systems with systematic, geo-referenced survey missions over water for the purposes of archaeological exploration and documentation.
