Java Sea

Map: world

Current relevance:

An Indonesian passenger vessel carrying 243 people reportedly sank in the Java Sea during bad weather; rescuers were searching for 140 people after 103 were evacuated, with one reported death, according to the report provided.

Continent: 

 The Java Sea is located in Asia, within Southeast Asia, and forms part of the Indonesian Archipelago.

Bordering Countries:

 The Java Sea lies within the Indonesian archipelago and does not directly border another sovereign country. For regional mapping, however, locate nearby Malaysia, Singapore, Brunei and Timor-Leste along with Indonesia.

Rivers Flowing into the Java Sea:

Several rivers from Java and Kalimantan drain into the Java Sea. The important Java-side systems include the Citarum, Ciliwung and Solo/Bengawan Solo rivers.

Important Places:

§  Java Island — Forms the principal southern boundary of the Java Sea and contains major population and economic centres.

§  Kalimantan (Borneo) — Lies to the north of the Java Sea.

§  Sumatra — Lies toward its western side.

§  Sunda Strait — Connects waters around the Java Sea with the Indian Ocean between Java and Sumatra.

§  Karimata Strait — Connects the Java Sea northwestward toward the South China Sea.

§  Makassar Strait — Lies east of the Java Sea, between Kalimantan and Sulawesi. Indonesia's Badan Informasi Geospasial (BIG) specifically identifies these geographic boundaries.

Significance:

§  Inter-island connectivity: The Java Sea occupies a central position among some of Indonesia's largest islands and is therefore important for domestic maritime transport and passenger movement.

§  Maritime crossroads: It connects with the Sunda, Karimata and Makassar straits, linking different parts of the Indonesian archipelago and surrounding seas.

§  Shallow shelf sea: With average depths of about 40–50 m, it forms part of the shallow Sunda Shelf, making it geographically distinctive.

§  Monsoon influence: Indonesia's official geospatial research records strong seasonal changes in Java Sea surface-water movement associated with the northwest and southeast monsoons.

§  Strategic Indonesian geography: Its position between Java, Sumatra, Kalimantan and Sulawesi makes it an important component of Indonesia's wider archipelagic maritime geography.
