continental margin (shelf, slope, and rise), on the Falkland 

 Plateau and North Scotia Ridge, and in the Argentine Basin. 

 All seismic reflection data from this work have been reduced 

 and plotted at a scale suitable for study and interpretation. 

 Preliminary solutions of layer thicknesses and velocity have 

 been computed and tabulated from all sonobuoy data. These 

 data are currently being used to: 



1. Plot structural sections along and across the con- 

 tinental margin provinces with particular attention 

 being placed upon the Rio Salado, Colorado, and 

 Malvinas basins. 



2. Determine the location and nature of the ocean- 

 continent boundary. 



3. Examine the detailed structure and plot sediment 

 thickness of the Falkland Plateau with a view to 

 determining the relationship between major struc- 

 tural elements in the plateau and features beneath 

 the Argentine continental shelf.
