7620 - Demarcation Bay to Liverpool Bay | Beaufort Sea Nautical Map

Navigate the remote and formidable coastline of the Western Arctic with Nautical Chart 7620. This official Canadian Hydrographic Service (CHS) chart provides essential, large-scale coverage for the Beaufort Sea, spanning the vast maritime corridor from Demarcation Bay (at the Alaska-Yukon border) to Liverpool Bay in the Northwest Territories.

As a primary resource for Arctic navigation, Chart 7620 is indispensable for vessels traversing the Northwest Passage and those involved in regional sealift, research, or environmental monitoring. This region is defined by its shifting ice conditions, shallow coastal shelves, and unique permafrost-affected shorelines. The chart features updated bathymetric soundings to identify hazardous shoals and identify safe deep-water routes far from the rugged coast. It provides critical data on coastal elevations, the positioning of remote navigational aids, and detailed mapping of the approaches to the Mackenzie River Delta. Whether you are commanding a commercial icebreaker or a specialized expedition vessel, this chart provides the professional accuracy required for safe pilotage in these challenging high-latitude waters.

Key Features:

• Expansive Arctic Coverage: Detailed mapping of the Beaufort Sea coastline from the Yukon-Alaska border to the entrance of Liverpool Bay.

• Hydrographic Precision: Includes essential depth data and bottom characteristics for navigating the shallow shelf waters of the Western Arctic.

• Strategic Mackenzie Delta Detail: Provides critical navigational context for the waters surrounding the mouth of the Mackenzie River.

• Safety & Pilotage: Clearly identifies hazardous reefs, coastal landmarks, and essential maritime data for extreme northern environments.
