explorer. At the Equator, cold currents are delineated by clouds over 

 8,000 miles of ocean in one television picture. The complex regions of 

 strong thermal gradients, such as the Gulf Stream in the Atlantic, and 

 the Kuroshio in the Pacific, are outlined hy infrared sensors » 



These views, however, have been limited initially by satellite 

 weight limitation, cloud cover, sensor resolution, and orbit altitudes. 

 Despite these limitations, oceanographers experienced in remote sensing 

 are trying to capitalize on the advantages of satellites. First, they 

 are refining present satellite sensors and exploring the use of new 

 oneso Secondly, they are examining closely the satellite information 

 now available, however gross, with the hope that they may infer 

 physical relationships not immediately apparent. Finally, they are 

 using satellites in conjunction with time-proven instruments on ships 

 and buoys to improve data transmission and navigational accuracy. 



Although future refinements in sensory instruments will provide 

 better data for analysis, the information from present instruments 

 will -facilitate the development of new approaches and methods for an 

 understanding of the oceans. It is with this hope in mind that this 

 report is presented ■>
