          Joint North Sea Data Acquisition Project for 1973 (JONSDAP 73)        
                                                                                
    This  is  the  second phase of the cooperative  data  collection  programme 
    JONSDAP  which was begun in 1970 by the countries bordering the North  Sea. 
    This phase, JONSDAP 73,  was a programme of tide and current measurement in 
    the Southern Bight of the North Sea from September to October 1973.         
                                                                                
    Other JONSDAP exercises:                                                    
                                                                                
    The  first JONSDAP achieved the systematic collection of data  from  moored 
    stations  and coastal observation sites in the North Sea in the period 1971 
    to  1973.  The third,  JONSDAP 76,  consisted of two intensive  measurement 
    programmes: i) FLEX, the Fladen Ground Experiment, to study the development 
    of  the  thermocline and the dynamics of the plankton bloom and ii)  INOUT, 
    concerned with the general circulation of the North Sea and the storm surge 
    problem.
