1972: Department of Public Works assessment

Upon request from the Government of the Northwest Territories, the federal Department of Public Works (DPW) [6] conducted a borehole campaign and erosion assessment for Tuktoyaktuk, specifically to advise on shoreline protection for the school. The primary mechanism of erosion was identified as thaw subsidence, and that any shoreline protection strategy should address ground ice thaw.
