7710 - Lambert Channel & Cache Point Channel Nautical Chart

The Northwest Passage Corridor: 7710 - Lambert & Cache Point Channels

Navigate the narrow and high-stakes passages of the Western Arctic with the professional authority of the Canadian Hydrographic Service (CHS). Chart 7710 is the definitive navigational guide for Lambert Channel and Cache Point Channel, two critical waterways situated within the Dolphin and Union Strait.

Critical Precision for Restricted Arctic Channels

As vessels transit between the Amundsen Gulf and Coronation Gulf, the narrow corridors of Lambert and Cache Point require extreme bathymetric accuracy. CHS Chart 7710 provides the "ground-truth" data required for:

• Tight-Navigation Safety: Features large-scale detail for the restricted channels, essential for deep-draft commercial vessels and expedition cruise ships maneuvering through the Inuvialuit Settlement Region.

• High-Resolution Bathymetry: Provides precise depth soundings and seafloor characteristics, allowing mariners to safely avoid the shoals and submerged hazards common to these Arctic straits.

• Coastal Orientation: Clearly defines the elevations and configuration of the Victoria Island and mainland coastlines, aiding in visual pilotage and radar positioning in low-visibility conditions.

• Seabed Nature: Identifies the composition of the sea bottom, providing vital information for anchoring or emergency stops in these isolated northern reaches.

The Standard for Arctic Transit

With the expansion of northern ocean resource development and the lengthening of the Arctic navigation season, the role of Chart 7710 is more vital than ever. Whether you are a captain of an ice-strengthened tanker, a marine researcher, or an Arctic explorer, this official CHS chart provides the precision required to ensure the safe navigation of these pivotal Western Arctic channels.
