Sediments in Karimata Strait by Kalimantan Barat, Borneo, Indonesia1S 109.5E
Brown sediments pour into the Karimata Strait from a river on the coast of Kalimantan Barat province, Borneo, Indonesia. The Karimata Strait is the wide strait that connects the South China Sea to the Java Sea, dividing the islands of Sumatra from Borneo (Kalimantan), both in Indonesia.
The strait is about 150 km wide, as measured from the east coast of the island of Belitung to the west coast of Borneo (Kalimantan). The Karimata islands lie in the eastern part of the Karimata strait, northeast of Belitung and off-shore from the west coast of Borneo. Some of those islands can be seen in the lower left quadrant of this image.
