7941 - Nansen Sound & Greely Fiord Nautical Chart

The Northernmost Frontier: 7941 - Nansen Sound & Greely Fiord

Navigate the absolute edge of the Canadian High Arctic with the professional authority of the Canadian Hydrographic Service (CHS). Chart 7941 is the essential navigational guide for the Nansen Sound Fiord System, providing the precision required for safe passage through the deep, glaciated waters between Ellesmere Island and Axel Heiberg Island.

Critical Precision for High-Latitude Discovery

As the northernmost conduit between the Arctic Ocean and the North Atlantic, Nansen Sound and Greely Fiord are defined by dramatic overdeepened basins, shifting ice barriers, and extreme environmental variables. CHS Chart 7941 provides the "ground-truth" data required for:

• Strategic Oceanographic Transit: Features a 1:300,000 scale, providing essential bathymetry for research icebreakers and expedition vessels studying Pacific water throughflow and multi-decadal variability.

• Complex Fiord Navigation: Provides detailed mapping of Greely Fiord, Canon Fiord, and the western approaches to Tanquary Fiord, identifying the steep underwater relief and sills (some as shallow as 128m to 175m) that influence deep-water flow.

• Hazard & Ice Barrier Awareness: Explicitly marks submerged rocks, shoals, and coastal configurations vital for navigating areas where "old ice" barriers often block passage until late summer.

• Topographical Orientation: Clearly displays the high-relief peaks and glaciers of the Grant Land Highlands, aiding in radar orientation and visual pilotage in a region with significant magnetic variation.

The Standard for Arctic Science & Exploration

With Arctic maritime traffic growing by 7% annually and summer sea-ice concentration becoming more variable, the role of Chart 7941 is more vital than ever. Whether you are conducting climate research, managing a high-latitude sealift, or leading a specialized polar expedition, this official CHS "road map" provides the accuracy needed to ensure safe navigation in the most remote maritime environment on the planet.
