Expatriation to the north, to South Georgia Island, occurs both as 

 a result of direct penetration of water from the Weddell Sea with the 

 current flowing along the arc of the South Sandwich Island, and as a 

 result of episodic transfer of surface water through its boundary zone 

 (Solyankin, 1969; Maslennikov et al . , 1971; Yelizarov et al . , 1973). 

 The transfer of crustaceans from the East Wind Drift is possible in 

 areas where the branches of the circulations which form it turn to the 

 north (Treshnikov, 1964). The movement of the surface water in this 

 direction has been described on the basis of satellite observations of 

 iceberg drift (Tchernia, 1974). As a result, a portion of the population 

 of E^. superba is scattered over the broad spaces of the Antarctic 

 beyond the limits of its main area of distribution. Such representation 

 agrees well with materials on the Quantitative distribution of krill 

 (Marr, 1956, 1962): Massive accumulations of crustaceans are related 

 to the East Wind Drift, the circulation of waters of the Weddell Sea, 

 regions of Bransfield Strait and South Georgia Island, i.e., they are 

 similar to the distribution of calyptopes, but somewhat broader. New 

 data (Mackintosh, 1973) have not carried us beyond the framework of this
