About Andaman Sea

• It is a semi-enclosed marginal sea in the northeastern Indian Ocean.
• It lies between the eastern coast of India and the Malay Peninsula, with Myanmar to the north and the Indonesian island of Sumatra to the south.
• The Bay of Bengal bounds the Andaman Sea to the west and the Strait of Malacca to the east.
• The sea, covering an area of approximately 307,994 square miles, extends about 750 miles in length and 400 miles in width.
• It is a complex geological region with a tectonically active plate boundary.
• It is part of the larger Sunda Plate, which the Indian Plate borders to the northwest and the Australian Plate to the southeast. 
• The ongoing tectonic convergence between these plates has resulted in the formation of the Andaman Basin, characterized by undersea ridges, trenches, and faults. 
• The most prominent geological feature in the region is the Andaman Trench, which is formed by the subduction of the Indian Plate beneath the Eurasian Plate. 
• This tectonic activity has given rise to numerous earthquakes and volcanic eruptions in the region, making the Andaman Sea seismically active.
• It is home to extensive coral reef systems, seagrass meadows, and mangrove forests, which provide critical habitats for a multitude of marine organisms.
  • It hosts many endangered fauna species –Whale Shark, Devil Manta Ray, Dugong, several dolphin species, such as Irrawaddy Dolphin and four species of sea turtles. 
  • It is also an important site for migratory birds, with several key stopover locations along the East Asian-Australasian Flyway.
• Islands: Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar.
• The climate of the Andaman Sea is tropical, with two distinct seasons: the southwest monsoon (May-September) and the northeast monsoon (November-February).
