Gulfs of the Celebes Sea

The Celebes Sea (Sulawesi Sea), bordered by the Philippines, Malaysia, and Indonesia, contains several notable gulfs and bays:

• Gulf of Bone (Teluk Bone) – South Sulawesi, Indonesia; large, deep, rich fisheries.
• Tolo Gulf (Teluk Tolo) – Southeast Sulawesi; nickel mining coast, coral reefs.
• Gulf of Tomini – North Sulawesi; equatorial, high biodiversity, volcanic islands (Togean).
• Gorontalo Gulf (Teluk Gorontalo) – North Sulawesi; whale shark aggregation site.
• Dondo Gulf (Teluk Dondo) – North Sulawesi, near Tolitoli.
• Buton Gulf (Teluk Buton) – Southeast Sulawesi, east of Buton Island.
• Gulf of Boni (Teluk Boni) – Often used interchangeably with Gulf of Bone; same feature.

These gulfs are vital for Indonesian fisheries, marine biodiversity (Coral Triangle), and emerging blue economy sectors (aquaculture, tourism, mining). Many face pressures from overfishing, sedimentation, and climate change.
