Abstract

The division of the region investigated according to P. CH. VEEN is redescribed. The micro salinity titration by means of the method described by G. H. ARNOLD with an accuracy of 0.1 ? was used for this investigation. This technique was adopted because of the large number of observations, and was sufficiently accurate since salinity in these waters varies widely. The annual range in salinity is large, caused by a considerable discharge of fresh water from the many big and small rivers, especially in the rainy-season as well as by the inequality of salinity of the oceanwaters coming from the East, and the South China Sea water coming from the West, during the dry and wet-sason respectively. In the east-monsoon, the eastern section is covered with ocean water over 34.0 ? and the western section with mixed waters ranging between 31.5 ? and 34.0 ?, while in the west-monsoon, the area is covered with mixed water less than 32.5 ?.

Abstract

A continuous northwest-going current prevails in the Strait of Malacca throughout the year, except June and August, when the currents are very weak and sometimes reversed  in the .southern part. The southern part of the Strait of Malacca is influenced by the currents. These currents transport low saline water into the Strait during the southwest monsoon and high saline water from the South China Sea during the northeast monsoon. In the northern part, the rainfall is of greater importance for the variations of the surface salinity and a strong correlation between rainfall and surface salinities is found in this region. It is unlikely that Indian Ocean water penetrates the South China Sea.

Abstract

This paper concerns investigations of the hydrography of the waters south of Java, especially of the Java Coastal Current, which have been carried out by the Institute of Marine Research at Djakarta. It is based on (1) oceanographic observations made by the research vessel "SAMUDERA" in February 1957, (2) the surface salinity data of the years 1949?1955, consisting of about 700 observations which were collected by the Institute of Marine Research at Djakarta, and (3) the surface current data obtained from the Atlas of Oceanographic and Meteorological data of the Koninklijk Nederlands Meteorologisch Instituut.
