Nine Degree Channel
The Nine Degree Channel is a channel in the Indian Ocean between the Laccadive Islands of Kalpeni and Suheli Par, and Maliku Atoll (Minicoy Island). These two subgroups of islands, together with the Amindivi Subgroup, form the Indian Union Territory (UT) of Lakshadweep. The Channel is approximately 200 km wide with a depth of 2597 metres. The Investigator Bank is located in the southern region of the channel. It is so named as it lies on the 9-degree line of Latitude, north of the equator. Sea Lane of Strategic Importance
