Passenger Vessel Grounding Shows Risks of Arctic Travel

Meanwhile, the low-water depth aural alarms on both echo sounders—regarded as a nuisance—had been turned off.

With more than 85 percent of Canadian Arctic waters having inadequate hydrographic data information, the likelihood of a similar occurrence involving passenger vessels engaged in adventure tourism is high.

According to Wikipedia it cost the Canadian Government half a million dollars to pull her off.

Evidently some navigators implicitly trust the soundings on the charts no matter how remote the area.

Canadian Arctic waters are inadequately surveyed and charted

3.17 Hydrographic surveys. Canada’s Arctic waters are vast and its coastlines are among the longest in the world. Although it is not reasonable to expect the entire Arctic to be surveyed to modern standards today, we did expect there to be reliable information for the higher-risk areas of the Arctic where vessel traffic is most prevalent, such as approaches to northern communities. However, we found that large areas of Canadian Arctic waters, including many of the main traffic corridors, have either non-existent or inadequate hydrography data coverage. The CHS estimates that about one percent of Canadian Arctic waters are surveyed to modern standards (Exhibit 3.4).
