OCEMOGRAPHIC CRUIHE - AUGUST 

 AND SEPTEMBER 196^+,

Figure 6 A comparison between satellite infrared data and oceanograpfiic 

 cruise and historical data 



Because of the sparse amount of data available on the coastal upwelling as well 

 ason the region's large fishing potential, the coast of the Somali Republic has long been 

 of interest to the authors. Scattered throughout this report (Figures 13, 14, and 22) are 

 specific examples of oceanographic information provided by satellites on this remote 

 region of the world. The charts shown on this page are a comparison of the sea surface 

 temperature information from the two Nimbus satellites, an oceanographic cruise by the 

 research ships ARGO and DISCOVERY, and an historical atlas of surface temperatures. 



L. J. Allison indicated that from 9°to 12°North, Nimbus 1 temperatures less than 

 63° F. are related to the position of stratus and stratocumulus clouds located over the 

 cold upwelled water. At this general time, an analysis of the ARGO-DISCOVERY data 

 shows that the 57.2°to 71.6° F. isotherms appear to underlie the cloudy region.
