دریای باندا بخشی از اقیانوس آرام است که منطقهای در شرق اندونزی مابین جنوب شرقی سولاوسی و شمال تیمور را دربر میگیرد. این دریا که توسط جزایر ملوک جنوبی محدود شدهاست در حدود ۹۷۰ کیلومتر طول و ۴۸۰ کیلومتر عرض داشته و مساحتی پیرامون ۴۷۰ هزار کیلومتر مربع را شامل میشود. ژرفترین نقطه در دریای باندا ۷٬۳۰۰ متر عمق دارد. همچنین دریاهای فلورس در غرب، ساوو در جنوب غربی، تیمور در جنوب، آرافورا در جنوب شرقی و سرام و ملوک در شمال آن قرار دارند.
وجود صخرهها (ریف) و جریانهای دریایی در اطراف جزایر این دریا میتواند برای کشتیها خطرآفرین باشد.
The Banda Sea is a sea in the Maluku Islands of Indonesia, connected to the Pacific Ocean but surrounded by hundreds of islands, as well as the Halmahera and Ceram Seas. It is about 1000 km (600 mi) east to west, and about 500 km (300 mi) north to south.
Islands bordering the Banda Sea include Sulawesi to the west, Buru, Ambon Island, Seram, Aru Islands, Barat Daya Islands, to the Tanimbar Islands, the Kai Islands and Timor in the East. Although the borders of the sea are hazardous to navigation, with many small rocky islands, the middle of the sea is relatively open. Island groups within the sea include the Banda Islands. A number of islands in the Banda Sea are active volcanoes including Gunung Api and Manuk in the Banda Islands.
Plate tectonic activities in Banda Sea
The Banda arc is famous for its 180° curvature and is, in Timor, generally agreed to be the product of collision between a volcanic arc and the Australian continental margin. The Banda Sea occupies the main portion of the Banda Sea Plate. The southern margin of the sea consists of island arcs above subduction zones. To the east of the Sunda Trench is the Timor Trough which lies south of Timor, the Tanimbar Trough south of the Tanimbar Islands and the Aru Trough east of the Aru Islands. These trenches are the subduction zone of the Indo-Australian plate beneath the Banda Sea Plate, where the Indo-Australian Plate moves northwards. Fore-arc sediments progressively carried northwards by the Indo-Australian Plate have been folded and faulted forming Timor island. To the northeast lies Seram Island which overlies the subduction of the Bird's Head Plate of West Papua. The deepest point of the sea, Weber Deep, is an exposed oceanic fault and the world's deepest forearc basin, with depth more than 7.2 kilometres (4.5 mi).
Earthquakes are very frequent in the area, due to the confluence of three tectonic plates - Eurasian, Pacific and Indo-Australian plates.
The Banda Islands, Tanimbar Islands, Kai Islands and other smaller islands in the Banda Sea have been designated as the Banda Sea Islands moist deciduous forests ecoregion, the eastern end of the Wallacea biogeographical region containing a mixture of plant and animal species from both Asia and Australasia. These islands are covered in mostly intact rain forest and home to a number of endemic plants and animals including twenty-one birds, a very high number for this small ecoregion. There are only twenty-two mammals on these islands including three endemics, the rare dusky pademelon (Thylogale brunii) and tomb bat (Taphozous achates), and an endangered mouse-eared bat, the Kei myotis (Myotis stalkeri). The birdlife is threatened by egg collectors and even more by cats and rodents that have been introduced to the islands. Yamdena in the Tanimbar Islands is an example of a large and fairly unspoilt habitat and is a protected area. The base for visiting these islands is by plane or ship from Ambon Island to the north, the largest of the Maluku Islands. The Banda and Kei Islands, although remote, are visited by tourists for snorkelling and for their unspoilt beaches. Various cetacean species have been recorded including either or both blue and pygmy blue whales and Omura's whales.
