It is situated in the Bay of Bengal, which is a northeastern extension of the Indian Ocean.The passage runs in a roughly north-south direction and separates Little Andaman Island to the west from Rutland Island to the east. The passage is approximately 48 kilometers (30 miles) long and ranges in width from 1.5 to 10 kilometers (1 to 6 miles). The depth of the water
History of the PassageThe history of Duncan Passage dates back to the early 19th century when it was named after Alexander Duncan, a British East India Company officer who surveyed the Andaman and Nicobar Islands. During World War II, the passage was used by Allied forces to supply troops stationed on the Andaman Islands.Today, the passage is not only a vital navigational route but also an important cultural and ecological resource. The area surrounding Duncan Passage is home to a rich variety of marine life, including several species of dolphins, whales, and sea turtles. The coral reefs and underwater rock formations in the passage provide habitat for a diverse range of fish and invertebrates.In recognition of its importance, the Indian government designated Duncan Passage as a National Nautical Byway in 2019. The National Nautical Byway program is designed to promote cultural, historical, and natural resources related to the country’s waterways. The program highlights significant waterways, encouraging the development of nautical tourism and promoting environmental conservation.The designation of Duncan Passage as a National Nautical Byway underscores the importance of protecting the area’s cultural and natural resources. It also offers new opportunities for sustainable tourism, highlighting the unique beauty and cultural heritage of the Andaman Islands. By promoting responsible use of the waterway and supporting local communities, the National Nautical Byway program is helping to ensure the long-term health and sustainability of this vital resource.
The Physical CharacteristicsThe passage is about 48 kilometers long and varies in width from 5 to 15 kilometers. Its physical characteristics have a significant impact on the region’s geography, marine life, and navigation.The depth of Duncan Passage varies significantly along its length, with some areas reaching depths of over 100 meters. The passage has a rocky seabed with numerous coral reefs and underwater rock formations. These features provide habitat for a diverse range of marine life, including several species of dolphins, whales, and sea turtles. The coral reefs and rocky formations also pose a risk to navigation, as ships must navigate carefully to avoid running aground or damaging their hulls.Tidal currents in Duncan Passage can be strong and unpredictable, making navigation challenging. The currents are influenced by the tide, wind, and local geography, and can change rapidly. Ships must carefully plan their routes to take into account the tidal currents and avoid being swept off course.The passage is also affected by the region’s monsoon climate. High winds and deluges are possible through the passage during the monsoon season (May–September). These weather conditions can make navigation even more challenging, and ships must take extra precautions to ensure their safety.
The Ecological Benefits Provided by Duncan PassageDuncan Passage, located in the Bay of Bengal, is an important ecological resource that provides a variety of benefits to marine life and the local environment. The passage and its surrounding waters are home to a rich variety of marine species, including several species of dolphins, whales, sea turtles, and fish.The coral reefs and underwater rock formations in the passage provide habitat for a diverse range of fish and invertebrates, such as groupers, snappers, surgeonfish, butterflyfish, and parrotfish. These habitats are essential for the survival of these species and contribute to the overall biodiversity of the region.A lot of marine animals, like humpback whales, Bryde’s whales, and spinner dolphins, use the passage as a way to move from one place to another. These animals rely on the passage for food, shelter, and breeding, and their presence in the area is an indicator of the passage’s ecological importance.The waters around Duncan Passage are also a vital source of food and livelihoods for local communities. Fishing is a significant part of the local economy, and many residents rely on the passage’s healthy fish populations for their subsistence and income. Sustainable fishing practices are crucial to ensure the long-term health and viability of the passage’s fish populations.Finally, the ecological benefits provided by Duncan Passage extend beyond the local region. The passage and the waters around it are part of the larger Bay of Bengal ecosystem. The Bay of Bengal is home to a huge number of marine species and is an important place for biodiversity around the world.
The History Behind the Fascinating Name of the Duncan PassageThe history behind the name of Duncan Passage is not entirely clear, but there are a few theories about how it got its name.One theory is that it was named after a British naval officer named Alexander Duncan, who served during the late 18th and early 19th centuries. Duncan was a prominent naval commander who played a role in several important battles and was known for his bravery and strategic acumen. It is possible that the passage was named in his honor, although there is no concrete evidence to support this theory.Another theory is that the passage was named after a ship or a sailor with the last name Duncan, who may have been involved in the early exploration of the Andaman and Nicobar Islands. The islands were visited by European explorers as early as the 16th century, and the British established a presence there in the late 18th century. It is possible that a ship or sailor named Duncan played a role in this early exploration and was honored by having the passage named after them.It’s important to know that no one knows for sure where the name Duncan Passage came from. However, the passage itself remains an important part of the region’s history and culture, and its name has become an enduring symbol of its significance.There is no link between Duncan Passage and Nantucket Island. Nantucket Island is near the coast of Massachusetts in the United States, while Duncan Passage is near the coast of India in the Bay of Bengal.

The National Nautical Byway (NNB) is a program launched by the Indian government to promote tourism and raise awareness about the country’s maritime heritage. The program aims to create a network of waterways that have cultural, historical, and natural significance, and to promote sustainable tourism and economic development in these areas.
Duncan Passage is known for its strong currents and treacherous waters, which have made it a challenging passage for ships and sailors to navigate. The passage is home to a variety of marine life, including whales, dolphins, and sea turtles, as well as coral reefs and other underwater ecosystems.
