The Java Sea covers the southern section of the 1,790,000 km 2 (690,000 sq mi) Sunda Shelf. A shallow sea, it has a mean depth of 46 m (151 ft). It measures about 1,600 km (990 mi) east-west by 380 km (240 mi) north-south [4] and occupies a total surface area of 320,000 km 2 (120,000 sq mi).
For US waters, the US Code of Federal Regulations require ships and their masters to calculate UKC based on the ship's deepest navigational draft. 33 CFR 157.450 The regulations require the master to discuss the UKC calculation with the maritime pilot as the ship approaches US ports/waters. 33 CFR 157.450
The rise of sea level during a meltwater pulse 14,600 to 14,300 years Before Present was as much as 16 meters within 300 years. [6] Present sea levels submerge a number of Pleistocene paleo river systems that drained much of Sundaland during the last glacial maximum 18,000 to 20,000 years ago. [7] To the east of the Sunda Shelf is the Sahul Shelf.
The strait is notoriously difficult to navigate because of this shallowness, very strong tidal currents, sandbanks, and man-made obstructions such as oil platforms off the Java coast. [ 3 ] For centuries, the strait was an important shipping route, especially during the period when the Dutch East India Company used it as the gateway to the ...
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward.
This is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) the design depth, and the German Navy sets it at exactly one-half (0.50) of design depth.

It is 3,200 kilometres (2,000 mi) long with a maximum depth of 7,290 metres (23,920 feet). [2] Its maximum depth is the deepest point in the Indian Ocean . The trench stretches from the Lesser Sunda Islands past Java , around the southern coast of Sumatra to the Andaman Islands , and forms the boundary between the Indo-Australian plate and ...
