The number of kidnappings in the Sulu Sea reached a 10-year peak prior to the Marawi Siege in 2017. These basins are within the 200-meter bathymetric contour except for the northeast and southeast portion where water depth ranges from 1,000 - 2,000 meters to as much as 5000 meters near the Sulu Trench. The water depth in the southern region changes rapidly, from over 4000 m in Sulu Sea to approximately 100 m in the area across the Sulu Archipelago, returning to over 4000 m in the Celebes Sea.

The Sulu Sea is described by the International Hydrographic Organization (IHO) as being one of the waters of the Archipelago of East India. In the Sulu Sea, there was a positive correlation between water depth and oxygen penetration depth, and oxygen penetration depth appeared to play an important role, along with organic carbon content, in determining the distribution of benthic foraminifera in the basin (Miao and Thunell, 1993). For this reason, the entire water column below 400 m is stable and homogeneous with respect to salinity (ca. Both interpretations are based on magnetic anomalies.
