The Gulf of Boni [1] (Indonesian : Teluk Bone), also known as the Gulf of Bone, Bay of Boni, and Bone Bay, is the gulf which divides the South and Southeast Peninsulas of the island of Sulawesi (Celebes) in Indonesia. It opens on the south into the Banda Sea. [2]
The International Hydrographic Organization (IHO) defines the Gulf of Boni (or Bone) as being one of the divisions of the East Indian Archipelago. [3] It is defined as the waters north of the "line from Tanjung Lassa, Celebes, to the North point of Kabaena Island ( 5°05′S121°52′E / 5.083°S 121.867°E ) and thence up this meridian to the coast of Celebes".

Sulawesi, also known as Celebes, is an island in Indonesia. One of the four Greater Sunda Islands, and the world's 11th-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and Papua are larger in territory, and only Java and Sumatra are more populous.
The Sulu Sea is a body of water in the southwestern area of the Philippines, separated from the South China Sea in the northwest by Palawan and from the Celebes Sea in the southeast by the Sulu Archipelago. Borneo is found to the southwest and Visayas to the northeast.
The Java Sea is an extensive shallow sea on the Sunda Shelf, between the Indonesian islands of Borneo to the north, Java to the south, Sumatra to the west, and Sulawesi to the east. Karimata Strait to its northwest links it to the South China Sea. It is a part of the western Pacific Ocean.
The Celebes Sea or Sulawesi Sea of the western Pacific Ocean is bordered on the north by the Sulu Archipelago and Sulu Sea and Mindanao Island of the Philippines, on the east by the Sangihe Islands chain, on the south by Sulawesi's Minahasa Peninsula, and the west by northern Kalimantan in Indonesia. It extends 420 miles (675 km) north-south by 520 mi (840 km) east-west and has a total surface area of 110,000 square miles (280,000 km2), to a maximum depth of 20,300 feet (6,200 m). South of the Cape Mangkalihat, the sea opens southwest through the Makassar Strait into the Java Sea.
Makassar Strait is a strait between the islands of Borneo and Sulawesi in Indonesia. To the north it joins the Celebes Sea, while to the south it meets the Java Sea. To the northeast, it forms the Sangkulirang Bay south of the Mangkalihat Peninsula. The strait is an important regional shipping route in Southeast Asia.
The Savu Sea is a small sea within Indonesia named for the island of Savu (Sawu) on its southern boundary. It is bounded by Savu and Raijua to the south, the islands of Rote and Timor to the east, Flores and the Alor archipelago to the north/northwest, and the island of Sumba to the west/northwest. Between these islands, it flows into the Indian Ocean to the south and west, the Flores Sea to the north, and the Banda Sea to the northeast.
The Banda Sea is one of four seas that surround the Maluku Islands of Indonesia, connected to the Pacific Ocean, but surrounded by hundreds of islands, including Timor, 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.
The Halmahera Sea is a regional sea located in the central eastern part of the Australasian Mediterranean Sea. It is centered at about 1°S and 129°E and is bordered by the Pacific Ocean to the north, Halmahera to the west, Waigeo and West Papua to the east, and the Seram Sea to the south. It covers about 95,000 km (59,000 mi) and its topography comprises a number of separate basins and ridges, the chief of which is the Halmahera Basin reaching a depth of 2039 m.
The Arafura Sea lies west of the Pacific Ocean, overlying the continental shelf between Australia and Western New Guinea, which is the Indonesian part of the Island of New Guinea.
The Gulf of Venice is an informally recognized gulf of the Adriatic Sea. It lies at the extreme north end of the Adriatic, limited on the southwest by the easternmost point of the Po Delta in Italy and on the southeast by the southernmost point of the Istrian Peninsula in Croatia. It is bordered by the coastlines of northeastern Italy and southwestern Croatia and Slovenia.
The Flores Sea covers 240,000 square kilometres (93,000 sq mi) of water in Indonesia. The sea is bounded on the north by the island of Celebes and on the south by the Sunda Islands of Flores and Sumbawa.
The Molucca Sea is located in the western Pacific Ocean, around the vicinity of Indonesia, specifically bordered by the Indonesian Islands of Celebes (Sulawesi) to the west, Halmahera to the east, and the Sula Islands to the south. The Molucca Sea has a total surface area of 77,000 square miles. The Molucca Sea is rich in coral and has many diving sites due to the deepness of its waters. The deepness of the water explains the reasoning behind dividing the sea into three zones, which functions to transport water from the Pacific Ocean to the shallower seas surrounding it. The deepest hollow in the Molucca Sea is the 15,780-foot (4,810-meter) Batjan basin. This region is known for its periodic experiences of earthquakes, which stems from the sea itself being a micro plate, in which the Molucca Sea is being subducted in two opposite directions: one in the direction of the Eurasian Plate to the west and the other in the direction of the Philippine Sea Plate to the east.
The Gulf of Tomini, also known as the Bay of Tomini, is the equatorial gulf which separates the Minahassa (Northern) and East Peninsulas of the island of Sulawesi (Celebes) in Indonesia. The Togian Islands lie near its center. To the east, the Gulf opens onto the Molucca Sea.
The Seram Sea or Ceram Sea is one of several small seas between the scattered islands of Indonesia. It is a section of the Pacific Ocean with an area of approximately 120,000 km2 (46,000 sq mi) located between Buru and Seram, which are two of the islands once called the South Moluccas. These islands are the native habitat of plants long coveted for their use as spices, such as nutmeg, cloves, and black peppercorns, and the seas surrounding them were busy shipping routes. The Seram Sea is also the habitat of several species of tropical goby and many other fish. Like many other small Indonesian seas, the Seram Sea is rocky and very tectonically active.
The Bali Sea is the body of water north of the island of Bali and south of Kangean Island in Indonesia. The sea forms the south-west part of the Flores Sea, and the Madura Strait opens into it from the west.
The East Indian Archipelago is an area designated by the International Hydrographic Organization (IHO). It encompasses twelve seas, two gulfs, and one strait in the East Indies.
The borders of the oceans are the limits of Earth's oceanic waters. The definition and number of oceans can vary depending on the adopted criteria. The principal divisions of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean. Smaller regions of the oceans are called seas, gulfs, bays, straits, and other terms. Geologically, an ocean is an area of oceanic crust covered by water.
The Gulf of Tolo, also known as the Bay of Tolo, is the body of water lying between the eastern and south-eastern peninsulas of the island of Sulawesi (Celebes) in Indonesia.
The Natuna Sea is an extensive shallow sea located around the Natuna Regency, extending south of the Riau Islands, east of the Lingga Regency and west of Borneo, to the Bangka Belitung Islands. The islands of the Badas and Tambelan Archipelago are located at its center. Mostly located within Indonesian territorial waters, it is the southernmost portion of the South China Sea, and geologically part of Sunda Shelf. It communicates with the Java Sea to its southeast via the Karimata and Gaspar Strait east and west of Belitung, and with the Strait of Malacca to the west via the Berhala and Singapore Strait.
