Geography
[edit]The Bali Sea is sometimes grouped with the Flores Sea foroceanographicpurposes; however, in somenautical charts,Bali Sea is written as a distinct sea for navigation. The sea has an area of 45,000 km2(17,000 sq mi) and a maximum depth of 1,590 m (5,217 ft).[2]
Extent
[edit]TheInternational Hydrographic Organization(IHO) defines the Bali Sea as being one of the waters of theEast Indian Archipelago.The IHO defines its limits as follows:[3]
On the North.A line from the Western Paternoster Island to the East point of Sepandjang and thence through this island to the West point of Gedeh Bay on the South coast ofKangean(7°01′S115°18′E/ 7.017°S 115.300°E).
On the West.A line from the West point of Gedeh Bay, Kangean Island, to Tg Sedano, the Northeast extreme ofJavaand down the East coast to Tg Bantenan, the Southeast extreme of the island.
On the South.A line from Tanjong Banenan through the Southern points of Balt [sic] andNoesaIslands to Tanjong Bt Gendang, the Southwest extreme ofLombok,and its South coast to Tanjong Ringgit the Southeast extreme, thence a line to Tanjong Mangkoen (9°01′S116°43′E/ 9.017°S 116.717°E) the Southwest extreme ofSoembawa.
On the East.The West and North coasts of Soembawa as far East as Tanjong Sarokaja (8°22′S117°10′E/ 8.367°S 117.167°E), thence the Western limit of Flores Sea [A line from Tg Sarokaja to the Western Paternoster island (7°26′S117°08′E/ 7.433°S 117.133°E)].
Circulation
[edit]The circulation and mass water properties in Bali Sea are a continuation from Flores Sea to theJava Seain the north. In oceanographic, Bali Sea is concerned with theIndonesian Throughflowcoming fromPacific Oceanto theIndian Ocean,the flow of which are mostly passing throughBali StraitandLombok Strait.[4]
Tsunamis
[edit]In a recordedtsunamihistory, Bali Sea observed several tsunamis. The1815 Tambora eruption(scale 7 ofVolcanic Explosivity Index) formed tsunamis on 22 September 1815 at coordinate8°00′S115°12′E/ 8.00°S 115.20°Eand three years later (8 September 1818) from subsequent volcanic activities at coordinate7°00′S117°00′E/ 7.0°S 117.0°E.[5]Two more tsunamis were recorded in 1857 and 1917 with maximum heights of 3 and 2 meters (9.8 and 6.6 ft) respectively.[5]
Accidents
[edit]2021
[edit]- On 21 April 2021, an Indonesian navy submarine calledKRI Nanggala (402)was reported as missing in waters about 95 km (51 nautical miles) north of Bali during its torpedo drill.[6][7]Few days later, debris was found within 10 nmi (19 km; 12 mi) of the point of last contact and was believed to have come from thesubmarine.Nanggala was later declared sunk along with 53 people on board, including 49 crew members, 1 commander, and 3 weapons specialists.[8][9]
