==Economic activities==

The southern section of the seafloor has long been recognized as geologically similar to northern Java, where oil fields occur and extend under the sea. Prospects are also favourablefavorable for oil fields in the waters off southeast [[Kalimantan]]. As the site of successful exploration for petroleum and natural gas, the Java Sea has become the basis of Indonesia's export program.

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 (Indonesia)|Thousand Islands]] are located north of the national capital [[Jakarta]], and are the city's only [[Regency (Indonesia)|regency]].

The area around the Java Sea is also a popular [[tourist]] destination. [[Scuba diving]] offers a chance to explore and photograph underwater [[cave]]rns, [[Shipwreck|wrecks]], [[coral]], [[sea sponge|sponge]]s, and other marine life.<ref>[[Nina Epton|Epton, Nina]] (1955).
