 meter 90 feet above the v;ater so that the recorded winds were 

 stronger than sxrrface values would be, second because readings 

 were made during only 10 irdnutes of each hour. The neasure:r.entB 

 are sufficiently accurate, however, to serve the purpose of cor- 

 relation with oceanographic phenomena.
