the coordinated use of survey ships, aircraft, and satellites with the maximum 

 use of expendable instrumentation. The use of expendable instrumentation from 

 both survey ships and aircraft facilitates coverage of the largest possible 

 area in the shortest possible time. Expendable Current Profilers (XCPs) would 

 provide extremely useful information on the current shear in the upper layers 

 of the Somali Current system. Further work on theoretical models is also 

 needed in order to explain the reasons for the behavior of the Somali 

 Current/Arabian Sea circulation system.
