Nine Degree Channel, Maritime strait between Laccadive Islands and Maliku Atoll, India
This strait lies between Kalpeni and Suheli Par on one side and Minicoy Island on the other, connecting two sections of the Indian Ocean. The waterway spans approximately 200 kilometers across and reaches depths exceeding 2,500 meters (8,200 feet) in certain areas.
The waterway received its name from its location on the ninth parallel north of the equator, making it an early navigational reference for seafarers. This geographic marker helped sailors orient themselves for centuries while crossing the Indian Ocean.
Fishing communities from the Lakshadweep archipelago depend on these waters for their livelihoods, casting nets and reading the ocean as part of generations-old traditions. Their connection to this seaway shapes how people in these islands understand their relationship with the sea.
Large merchant ships use this passage to travel between Europe, Asia, and the Middle East, making it one of the world's busier shipping routes. Visitors can experience this seaway best from the surrounding islands or during boat trips that cross the channel.
The Investigator Bank, a submerged underwater ridge, lies in the southern section and creates hidden challenges for navigation that sailors must carefully avoid. This underwater formation causes currents to shift in unexpected ways, making the waters here trickier than they first appear.
