Navigate the northernmost reaches of the Canadian Arctic with the professional authority of the Canadian Hydrographic Service (CHS). Chart 7920 is the definitive navigational authority for the deep-water inlets of Ellesmere Island, providing the high-latitude precision required for safe passage through Tanquary, Slidre, and Glacier Fiords.
This region is the gateway to Quttinirpaaq National Park, characterized by ancient glaciers, dramatic coastal elevations, and the world’s most northerly scientific outposts. CHS Chart 7920 provides the "ground-truth" data required for:
Strategic Access to Tanquary Fiord: Features precise bathymetry for the 48 km inlet, essential for icebreaker cruise ships and charter vessels servicing the Parks Canada Warden Station.
Safe Approaches to Slidre Fiord (Eureka): Provides the necessary detail for vessels supplying the Eureka Weather Station, ensuring safe transit through the deep, ice-prone waters of the central Ellesmere coast.
Glacial Coastline Mapping: Clearly defines the configuration of the coast where active valley glaciers meet the sea, identifying shifting ice-tongues and potential calving hazards.
Seabed & Hazard Identification: Explicitly marks submerged dangers, the nature of the sea bottom, and elevations—critical for anchoring in some of the most remote maritime environments on Earth.
With the expansion of Arctic tourism and the vital role of climate monitoring in the High North, the role of Chart 7920 is more vital than ever. Whether you are a captain of an ice-strengthened research vessel, a pilot for a northern supply mission, or an expedition navigator, this official CHS "road map" provides the precision required to ensure safe navigation at the absolute edge of the world.
