and to provide certain facilities which were necessary to such a 

 large international undertaking. Special customs agreements were 

 arranged and courtesies were provided for ships and personnel 

 taking part in the expedition. Within the framework of UNESCO, 

 the Intergovernraentyl Oceanographic Commission (lOC) and the Office 

 of Oceanography were established and coordination of the expedition 

 was assumed by the IOC secretary. This coordination is maintained 

 through working groups and through the IOC Information Paper which 

 is issued by UNESCO. Participating nations supply information of 

 their activities through national coordinators for IIOE. 



SCOR remained responsible for the advisory aspects of the 

 expedition and a small group of scientific specialists were 

 appointed as disciplinary experts for the expedition: Professor 

 J. Krey (Germany); phytoplankton, zooplankton, primary pro- 

 duction, pigments; Professor L. A. Zenkevich (U.S.S.R. )j benthos, 

 mid-water and deep fauna; Professor P. Tchernla (France): aynamlcs 

 and circulation, chemistry. 



In addition Dr. R. L. Fisher was requested to advise on the 

 geological and geophysical aspects of the expedition. These experts 

 were required to review and evaluate IIOE programs in their respec- 

 tive fields. 



An international sorting station for zooplankton was developed 

 on the advice of the IIOE biological working group. This station 

 is known as the Indian Ocean Biological Center and wa-s established 

 in 1963 at Ernakulam, South India. Participating ships send 

 samples which are taken in a standard IIOE net to the center for 

 sorting and later analysis.
