In 2015, Parks Canada embarked on The Franklin Expedition: Mission Erebus and Terror 2015. R2Sonic’s 2022 (on the Canadian Coast Guard Ship (CCGS) Sir Wilfrid Laurier and the Canadian Hydrographic Service), 2024-UHR (on the Parks Canada survey vessel Investigator) and 2026 multi beam echo sounder, (on the Royal Canadian Navys HMCS Moncton), were used in the two week mission in 2015. The devices not only provided high-quality multibeam data that supported the ongoing search for the still unaccounted for Franklin Expedition vessel HMS Terror, but also gathered data suitable for use in charting within high priority navigation corridors in Victoria Strait according to Canadian Hydrographic Service standards.

In this article, featured in the April 2016 issue of Hydro International, Mike Brissett of R2Sonic, LLC and Tim Janzen of the Canadian Hydrographic Service discuss the knowledge gained and multiple uses of the data collected for hydrographic products that allow safe and efficient navigation in these corridors and toward the conclusion of verifying where HMS Terror is not located.
