The route around the largest of the Guyou Islands in Flandres Bay was first charted by the Belgian Antarctic Expedition in 1898, followed by the French Antarctic Expedition in 1904 and 1908-1911.
Oceanwide passengers, guides and crew helped map the area on December 11 over the course of a day, with the the voyage’s expedition leader, field operations manager, second mate, and other members of on board staff part of the group.
The Olex navigation and mapping system by Olex in Norway was used for the task. It employs sonar and GPS to collect and continuously update sea depth data, producing 3D visualisations of the seabed in real time.
Passengers were able to share their data with the Trondheim-based company, contributing to its database of more than 5b measured depths - information which can be used in fishing, port work, aquaculture, and subsea piping, and more.
