3827 - Tasu Sound Nautical Chart

The Fortress of the West Coast: 3827 - Tasu Sound

Navigate the dramatic and sheltered waters of Tasu Sound with the professional precision of the Canadian Hydrographic Service (CHS). Chart 3827 is the definitive "road map" for mariners seeking entry into one of the only deep-water harbors on the exposed West Coast of Moresby Island, Haida Gwaii.

Critical Data for Deep-Fjord Navigation

Tasu Sound is characterized by its narrow, high-relief entrance and expansive inner basins. CHS Chart 3827 is specifically designed to meet the requirements of this complex environment:

• High-Detail Bathymetry: Essential for navigating the deep glacial waters and identifying the sudden shallowing near the sound's various arms and inlets.

• Tidal and Current Information: Provides critical data for the entrance to Tasu Sound, where Pacific swells meet the outward flow of the fjord.

• Submerged Hazards: Clearly marks the rocky pinnacles and reefs that guard the entrance, ensuring safe passage for commercial ships and recreational explorers alike.

• Coastal Configurations: Features detailed elevations of the surrounding mountains—vital for radar pilotage and visual orientation in the frequently foggy conditions of the North Pacific.

Essential for Maritime Operations

As interest in the development of ocean resources and boutique Arctic-style expeditions in Haida Gwaii grows, the role of Chart 3827 is more vital than ever. Whether you are seeking a heavy-weather refuge, conducting marine research, or navigating toward the historic Tasu site, this chart provides the official data needed for safe, port-to-port navigation.
