    Saleh Bay is a key for the reconstruction of the late Pleistocene and Holocene history of Sumbawa, especially of events associated with volcanic eruptions of Mt. Tambora and eustacy in the aftermath of the Weichselian ice age. Piston cores of up to 9 m length retrieved from a 'crater lake' of a submerged subsidiary volcano provide an uninterrupted record of the past 30 000 years as ascertained by radiocarbon techniques on authigenic marine shell material. Shape of crater indicates that the small volcano once stood above sea level. In as much as similarly shaped 'craters' populate the Bay floor, it is proposed that Saleh Bay has started to subside in late Pleistocene. It is suggested that this incident is related to the drainage of a magma chamber in the course of the ascend of Mt. Tambora.
