The 10 Degree Channel is located in the southeastern part of the Bay of Bengal in the Indian Ocean region. It lies approximately along 10° North latitude, which is the reason behind its name.
This channel is situated between the Andaman Islands and the Nicobar Islands of India. More specifically, it separates Little Andaman Island in the north from Car Nicobar Island in the south.
The 10 Degree Channel also acts as an important maritime link connecting the Bay of Bengal with the Andaman Sea. Due to its strategic location near major international shipping routes, it holds great importance for navigation, defence, and maritime security.
The map of the 10 Degree Channel shows its location between the Andaman Islands and the Nicobar Islands in the Bay of Bengal region. The channel lies approximately along the 10-degree north latitude and acts as a natural boundary between the two island groups of India.
On the northern side of the channel lies Little Andaman Island, while Car Nicobar Island is located on the southern side. The channel connects the Bay of Bengal with the Andaman Sea, making it an important maritime route in the Indian Ocean region.
The map below helps in understanding the exact location and geographical position of the 10 Degree Channel.
The 10 Degree Channel holds immense strategic importance for India due to its location in the Indian Ocean region and proximity to major international shipping routes.
Maritime Trade Routes: The channel lies close to important global maritime trade routes connecting the Indian Ocean with Southeast Asia. A large volume of international cargo ships and oil tankers pass through nearby waters, making the region economically significant.
Naval Movement and Surveillance: The deep waters of the channel support the movement of naval ships, submarines, and surveillance vessels. This helps India maintain maritime awareness in the Bay of Bengal and nearby sea regions.
India’s Maritime Defence: The channel plays an important role in strengthening India’s maritime defence system. Its location allows Indian naval forces to monitor activities in the eastern Indian Ocean and secure India’s island territories.
Indian Ocean Security: The 10 Degree Channel contributes to regional security by helping India monitor piracy, illegal fishing, smuggling, and unauthorized maritime activities in the Indian Ocean region.
Strategic Monitoring of Shipping Lanes: Because several international shipping lanes pass close to the Andaman and Nicobar Islands, the channel helps India keep strategic control over important sea routes used for global trade and energy transportation.
Role in Andaman and Nicobar Command: The channel is strategically linked with the Andaman and Nicobar Command, India’s only tri-service military command. This command enhances coordination between the Army, Navy, and Air Force for coastal and maritime security operations.
Indo-Pacific Strategic Relevance: In recent years, the Indo-Pacific region has become highly important in global geopolitics. The 10 Degree Channel strengthens India’s strategic presence in the Indo-Pacific and supports cooperation with friendly countries in maintaining freedom of navigation and regional stability.
The 10 Degree Channel and the 9 Degree Channel are both important maritime channels associated with India’s island territories. However, they differ in location, the islands they separate, and their strategic importance in the Indian Ocean region.
