Navigate the turbulent and ice-dynamic waters of the High Arctic with the professional authority of the Canadian Hydrographic Service (CHS). Chart 7930 is the definitive navigational guide for Hell Gate and Cardigan Strait, the two narrow corridors that connect Jones Sound to Norwegian Bay.
Hell Gate and Cardigan Strait are known for some of the most challenging tidal currents and ice movements in the Canadian Arctic. Precision is not just a preference; it is a safety requirement. CHS Chart 7930 provides the "ground-truth" data required for:
Strategic Transit Planning: Features 1:75,000 scale detail, essential for expedition icebreakers and research vessels transiting the narrow passages between Devon Island and North Kent Island.
High-Resolution Bathymetry: Provides accurate depth soundings and seafloor characteristics—crucial for navigating channels where the narrowing of the coast intensifies water velocity.
Hazard & Ice Management: Clearly marks submerged rocks, shoals, and coastal elevations, aiding in visual pilotage and radar positioning in the frequent fog and variable ice conditions of the North.
Seabed Nature: Identifies bottom composition, providing vital data for anchoring or scientific sampling in the ecologically rich waters near the North Water Polynya.
With the expansion of Arctic maritime traffic and the increasing focus on northern ocean resources, the role of Chart 7930 is more vital than ever. Whether you are a captain of a scientific research vessel, a specialized Arctic pilot, or a logistics officer for a northern mission, this official CHS "road map" ensures you have the most up-to-date information on depths, dangers, and aids to navigation.
