Defining the Degrees

Do you know that the 8, 9, and 10 ° Channels are primarily maritime channels.

It is situated in the Indian Ocean.

They are extremely crucial for maritime trade, international navigation, and even a hint of geopolitics.

8° Channel:

It separates India’s Andaman & Nicobar Islands with Indonesia.

This channel is located between the southernmost tip of India’s Andaman Islands and the northernmost tip of Indonesia’s Island.

It is important for navigation between the Bay of Bengal and the Andaman Sea.

9° Channel:

9 Degree is situated further to the south.

Separates the islands of Minicoy from the main Lakshadweep Archipelago.

It is 200 km wide and approximately 2500 m deep.

The 9 Degree Channel separates the Little Andaman with Great Nicobar.

The Little Andaman, which belongs to India is separated from the Great Nicobar Island, which is part of the Indian union territory.

It is an important route for shipping in the region.

All the ships coming from Middle-East, Europe, West Asia and South – East Asia passes through 9 Degree channel.

Therefore, it has a very strategic importance.

10° Channel:

10° is located to the south of the 9 ° Channel.

It separates Andaman Islands with the Nicobar Islands.

It is 150 km wide.

From east to west it is 10 km wide with a depth of approximately 7 meters.

This passage divides the Car Nicobar island, an Indian territory, from the Nancowry Group of Islands.

Similar to the other channels, it is a key navigation route for ships and has strategic importance.

It is named so because the 10 degree latitude separates Andaman with Nicobar islands.

Historical Significance

These channels are vital for contemporary maritime activities.

Also held historical significance.

During the colonial period, the British recognized the importance of these channels for trade and control of the Indian Ocean.

They established lighthouses and naval bases along these passages to safeguard their interests.

The 8 Degree Channel, in particular, has played a role in the history of World War II.

It was the site of naval battles and skirmishes as the British attempted to secure the region against Japanese advances.

Geopolitical Significance

These channels also have geopolitical importance in modern times.

Their location are critical to India’s maritime (SEA COAST) security.

They serve as entry points to the Indian Navy’s Eastern and Western Fleets.

Furthermore, their proximity to the Strait of Malacca, one of the world’s busiest shipping lanes, highlights their strategic significance.

Additionally, the 8 Degree Channel has been a subject of discussion between India and Indonesia.

This is because of the overlapping Exclusive Economic Zones (EEZs) of both the nations.

However, resolving these maritime boundary issues has been a subject of diplomatic negotiations.

Biodiversity and Ecology

The waters surrounding these channels are also known for their rich biodiversity.

The coral reefs (for which Lakshadweep is known for marine life), and the lush underwater world are treasures of the Indian Ocean.

The conservation of these ecosystems is essential.

These ecosystems support the livelihoods of coastal communities.

Indian geography is a tapestry of diverse landscapes, cultures, and climates.

It’s a land of extremes, from the snow-capped peaks of the Himalayas to the sun-soaked shores of the Indian Ocean.

In this rich tapestry, there are some fascinating latitudinal lines that are worth exploring: the 8th, 9th, and 10th degrees of latitude in Indian geography.

The 8th Degree: A Glimpse of the Southern Tip

The 8th degree of latitude in India marks the southernmost extent of the mainland.

It is a region that offers a unique blend of geographical and cultural diversity.

Kanyakumari, located near this latitude, is the southernmost point of the Indian subcontinent.
