Diamantina Deep referred to a sea ​​depression in the Diamantina Fracture Zone in the southeast Indian basin , which according to the GEBCO Undersea Feature Names Gazetteer was designated as the deepest point in the Indian Ocean with a depth of 8047 m . This was due to investigations by the Australian naval ship HMAS Diamantina in 1960.

In 2019, an expedition of examined Victor Vescovo , with the dive boat Limiting Factor the lowest points of all oceans wanted to reach the area with a lander and a fan echo sounder . During the mapping, however, only a maximum depth of 7019 m ± 17 m was found in the Diamantina Fracture Zone and this was at the point of the Dordrecht Depth . The indicated position of the Diamantina Depth at 35 ° South and 104 ° East is outside the actual Diamantina Fracture Zone at depths of approximately 5300 m. Stewart and Jamieson come to the conclusion in a survey study that if the name "Diamantina Deep" is to be retained, its position must be moved into the fracture zone - although it would be unclear exactly where. The deepest part of the Indian Ocean has since been located in the Java Trench .
