4000 Nautical Chart: Gulf of Maine to Baffin Bay | Official CHS Marine Chart

Navigate the vast expanse of the Northwest Atlantic with the 4000 Gulf of Maine to Baffin Bay nautical chart. Published by the Canadian Hydrographic Service (CHS), this small-scale "General Chart" is a foundational tool for offshore mariners, oceanographers, and commercial shipping operators. It provides a comprehensive overview of the eastern seaboard and the Arctic approach, stretching from the temperate waters of the Gulf of Maine to the high-latitude reaches of Baffin Bay.

As a strategic planning chart, the 4000 series is essential for long-range passage planning and deep-sea navigation. It bridges the gap between coastal charts, offering a wide-angle perspective of the Atlantic maritime corridor. This chart is engineered to professional standards and includes critical technical details:

• Large-Scale Overview: Rendered at a 1:5,000,000 scale, making it the primary reference for trans-Atlantic and Arctic transit planning.

• Deep-Sea Bathymetry: Accurate water depth soundings and contour lines across the Continental Shelf and into the deep ocean basins of the Labrador Sea.

• Oceanic Features: Detailed mapping of major submarine features, including banks, trenches, and the topography of the North Atlantic floor.

• Navigational Hazards & Major Aids: Identification of significant offshore hazards and primary navigational aids used for landfall and long-range positioning.

• Geospatial Standards: Built using the North American Datum 1983 (NAD83), ensuring total synchronization with global GPS systems and electronic chart display and information systems (ECDIS).

Whether you are planning a research expedition to the Arctic or managing commercial vessel traffic along the eastern coast of North America, this official CHS chart delivers the technical accuracy and spatial context required for safe, high-seas navigation.
