Fishing is an important economic activity in the Java Sea. Over 3,000 species of marine life are found in the area. A number of national parks exist in the area such as Karimunjawa. The Thousand Islands are located north of the national capital Jakarta, and are the city's only regency. The area around the Java Sea is also a popular tourist ...
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 Sahul Shelf and the Sunda Shelf today. The area in between is called "Wallacea"Sundaland [1] (also called Sundaica or the Sundaic region) is a biogeographical region of Southeast Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower.
The Wallace Line represents a sea barrier that has persisted, as far as is known, even at the lowest sea levels of glacial maxima of the Pleistocene and the Holocene. Therefore we know when watercraft of some (admittedly unknown) description must have been used by humans to cross the sea. [5]: 15
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 ...

At the peak of either monsoon, the current can run up to 6 kilometres per hour (3 nautical miles per hour) When the monsoon is light, "there is little or no current" and the direction may be subject to the tidal stream. [10] The strait's currents run between the South China Sea to its north and the Java Sea to its south. [11]
The original drawing of the line in Wallace's paper. One of the earliest descriptions of the biodiversity in the Indo-Australian Archipelago dates back to 1521 when Venetian explorer Pigafetta recorded the biological contrasts between the Philippines and the Maluku Islands (Spice Islands) (on opposite sides of the Wallace's Line) during the continuation of the voyage of Ferdinand Magellan ...
