Diamantina Fracture Zone
The Diamantina Fracture Zone (DFZ) is an area of the south-eastern Indian Ocean seafloor, consisting of a range of ridges and trenches.[1] It lies to the south of the mideastern Indian Ocean features of the Wharton Basin and Perth Basin, and to the south west of the Naturaliste Plateau.

The Diamantina Fracture Zone was first detected by
Bathymetry
The first high-resolution multibeam bathymetry of the central DFZ was collected between June 2014 and June 2016, for the purpose of searching for Malaysia Airlines Flight 370 (MH370), which disappeared on 8 March 2014.[5] This revealed that the DFZ has a depth of more than 5,800 m (19,000 ft).[5] Later research using multibeam bathymetry data available from Geoscience Australia and the GMRT (Global Multi-Resolution Topography) Synthesis, infilled with data derived from the GEBCO_2014 global bathymetry dataset, suggested that the deepest point in the fracture zone would be at 33°27′07″S 101°28′05″E / 33.452°S 101.468°E in the Dordrecht Deep, within the axis of the fracture zone, with a maximum water depth of between 7,090 to 7,100 metres (23,260 to 23,290 ft).[6]
Based on this research, it was suggested that the Dordrecht Deep within the DFZ in the southeast Indian Ocean, and the Sunda Trench in the eastern Indian Ocean (~11°12′S 118°30′E / 11.2°S 118.5°E), are the two candidates for the deepest points in the Indian Ocean.[7]
To resolve this debate, the Diamantina Fracture Zone was surveyed by the
The shallowest point in the area is the 1,125 m (3,691 ft) point in the Broken Ridge, close to Ninety East Ridge.[8]
