Celebes Sea

The Celebes Sea is a large part of the ocean.

It has warm and clear water. Many animals live in the sea. You can find whales and dolphins there.

Sea turtles and big rays swim in the water too. Many colorful corals grow on the sea floor. These corals make a home for many fish. The sea is also a busy place for boats. People like to dive in the water there. It is a very special place to explore.

The Celebes Sea is a large part of the Pacific Ocean.

It sits near many islands. It is bordered by the Philippines and Indonesia. The sea has warm and clear water. This helps many living things grow.

Many colorful corals live here. These corals build reefs. These reefs are some of the most diverse in the world. This means they have many different kinds of life. You can find whales and dolphins in the sea.

Many fish like tuna live there too. Even squid live in these waters.

The sea has a very old history. It began as an ocean basin 42 million years ago. Long ago, the earth's crust moved. This moved the basin near volcanoes. The sea then received debris from them. Later, it received coal from a mountain on Borneo.

The sea floor has many shapes. It has deep trenches and seamounts. A seamount is an underwater mountain. The sea also has strong currents. These currents move the water. People use the sea for trade. They also go there to dive.

The Celebes Sea is a large part of the western Pacific Ocean.

It sits between many different lands and islands. To the north, it meets the Sulu Archipelago and Mindanao Island. The Sangihe Islands sit to the east. To the south is the Minahasa Peninsula. The west side is bordered by northern Kalimantan in Indonesia. This sea is very big and quite deep. It covers a huge surface area.

This sea has many special shapes on its floor. It has deep sea trenches and seamounts. A seamount is like an underwater mountain. The water also has strong ocean currents. These currents move the water around. The bottom of the sea sits on an oceanic plate. This plate has a spreading center in the middle. The plate also slides under other plates to the north and south. This movement makes the ocean floor very complex.

The Celebes Sea has a very long history. It started as an ancient ocean basin. This basin formed about 42 million years ago. It was far away from any land back then. By 20 million years ago, the earth's crust moved. This movement brought the basin near volcanoes in Indonesia and the Philippines. The sea began to receive debris from those volcanoes. By 10 million years ago, the basin had docked against Eurasia. It also received coal from a young mountain on Borneo.

Many living things call this sea their home. The water is warm and clear. This helps about 580 types of reef-building corals grow there.

These reefs are some of the most diverse in the world. You can see whales and dolphins swimming in the waves. Sea turtles and manta rays live here too. Many fish like tuna and yellowfin tuna are very common. You might even see squid or sea tang.

People use the Celebes Sea in many ways today. It is an important path for regional trade. Ships use these waters to move goods from place to place. The sea is also a popular spot for fun. Many people go scuba diving in the clear water. Others enjoy luxury ocean cruising. On May 23, 2013, the Philippines and Indonesia signed an agreement. They set a boundary line for their economic zones. This helps both countries manage the sea fairly.

The Celebes Sea is a significant body of water in the western Pacific Ocean. It is also known as the Sulawesi Sea. This sea is surrounded by several different landmasses and island chains. To the north, it is bordered by the Sulu Archipelago, the Sulu Sea, and Mindanao Island in the Philippines. The Sangihe Islands form its eastern boundary. To the south lies the Minahasa Peninsula of Sulawesi. The western edge is defined by northern Kalimantan in Indonesia.

The sea is a vast area with a massive surface area. It reaches a maximum depth of 6,000 meters. It connects to the Java Sea through the Makassar Strait, which opens southwest from Cape Mangkalihat.

The geology of the Celebes Sea is quite complex. The floor of the sea is underlain by an oceanic plate. This plate features a mid-oceanic spreading center in its middle section. This means the crust is pulling apart in the center. At the same time, the plate is subducted to the north and south. Subduction occurs when one tectonic plate slides beneath another. This movement creates deep sea trenches and seamounts, which are underwater mountains. These geological features, along with active volcanic islands and strong ocean currents, make the sea's oceanographic environment very intricate.

The history of this sea begins millions of years ago. It started as an ancient ocean basin that formed 42 million years ago. At that time, the basin was located in a place far removed from any landmass. About 20 million years ago, the movement of the Earth's crust changed things. This movement brought the basin close to volcanoes in Indonesia and the Philippines. As a result, the sea began to receive debris emitted from these volcanoes.

By 10 million years ago, the basin had docked against Eurasia. During this time, it was inundated with continental debris. This included coal that was shed from a growing young mountain on Borneo.

The biological diversity of the Celebes Sea is remarkable. The tropical setting provides warm and clear waters. These conditions allow about 580 of the world's 793 species of reef-building corals to live there. These corals form some of the most bio-diverse coral reefs on the planet.

The sea is also home to many large marine animals. You can find whales, dolphins, sea turtles, manta rays, and eagle rays. Many fish species live here as well, such as barracuda and marlin. Tuna and yellowfin tuna are particularly abundant in these waters. Other aquatic products, such as sea tang and squid, are also found here.

Because the sea is so large, different countries must manage their rights to its resources. This involves the Exclusive Economic Zone, or EEZ. An EEZ is an area where a country has special rights over marine resources. On May 23, 2013, the Philippines and Indonesia signed an agreement. This agreement established a boundary line to manage their overlapping zones. North of this line, the waters are under the jurisdiction of the Philippines and are called the Mindanao Sea. South of the line, the waters belong to Indonesia and are called the Celebes Sea.

Human activity in the Celebes Sea is significant for several reasons. It serves as an important sea route for regional trade, where ships carry goods between nations. The area is also a major destination for tourism. Many people visit the sea for scuba diving in its clear waters. Others enjoy luxury ocean cruising through the region.

These activities show how the sea is connected to both global economics and recreation.

The Celebes Sea is a vital part of the East Indian Archipelago. The International Hydrographic Organization (IHO) defines its specific limits using various islands and points. For example, the northern limit includes the Sulu Sea and the coast of Mindanao. The eastern limit follows a line from Tinaca Point to the Sangihe Islands. The southern limit runs along the north coast of Celebes and through the Makassar Strait. The western limit is defined by the east coast of Borneo. These boundaries help scientists and governments understand the exact extent of this unique marine system.
