OCEAN CURRENTS 197 



between 10 and 27 south in winter, but farther north — i.e., up 

 to 5° S. Lat. — in the northern summer. There is an Equa- 

 torial counter-current in winter, running easterly from 2° to 

 5° S. Lat. ; this disappears in the northern summer. 



At the period of the south-west monsoon the gênerai drift 

 of the currents in the Northern Indian Océan is easterly, and 

 this tendency is felt in the Red Sea as far as the Suez Canal, 

 so that Mediterranean water enters the Red Sea at this 

 time. Water flows out through the Gulf of Aden into the 

 Arabian Sea. 



The Indian South Equatorial Current strikes the island of 

 Madagascar, where it splits into branches in about 10° S. 

 Lat., one running south along the coast as the Mozambique 

 Current, ultimately becoming, south of 30° S. Lat., the 

 Agulhas Current. South of the Tropic of Capricorn this 

 current bends to the east, and merges into the South Atlantic 

 easterly current. Where the Agulhas Current merges into the 

 colder water of the South Atlantic drift there are fréquent 

 changes recorded in the surface températures. 



Running up the western side of Australia is the West 

 Australian Current, analogous to the Benguela Current of the 

 Atlantic. Far south there is an easterly current which is a 

 continuation of the gênerai Antarctic drift. Drift-bottles set 

 free off Cape Horn hâve been found on the south coast of 

 Australia and the west coast of New Zealand. One such 

 bottle drifted from the southern part of the Brazil Current to 

 the north of New Zealand in three and a half years, a distance 

 of 10,700 sea-miles. It is more than likely that there is a 

 current right round the world in thèse latitudes.
