Oceanographic images and videos collected during the Pushing the Boundaries: Using Advanced Technology to Locate and Rapidly Assess Cultural Sites in Multiple Underwater Environments within NOAA's Thunder Bay National Marine Sanctuary Expedition on NOAA R/V Storm and R/V Laurentian in Lake Huron, Michigan from 2017-04-10 to 2017-08-30

This dataset contains oceanographic images and videos taken with a Seaeye CAM04N Forward Looking Camera, a Seaeye P13946-1 Rear Looking Camera, a Saab Seaeye Falcon ROV, and a Kongsberg 1171 Mini Head Single Beam Scanning Sonar. This project sought to develop innovative, technology-centered, and repeatable methodologies for locating and rapidly assessing cultural sites in shallow (less than 20 feet) and deep water greater than 130 feet) areas. This project experimented with cutting-edge equipment and techniques. The deepwater survey segment involved looking for the historically significant wreck of steamer Choctaw, while the shallower survey focused on known "ship traps", determined via analysis of the region's coastal geography and historical use.
