Refraction infomiation is presented covering swell periods of 

 18 5 22, 26, and 30 sees. The principal results are presented 

 by the polar diagram method for each of six stations. 



"Results of Research on Surface Waves of the Western North Atlantic," 

 H„ R= Seiwell, Woods Hole Oceanographic Institution, Papers in 

 Physical Oceanography and Meteorology, Vol. X, NOo 4> Aug» 19^-8 » 



Bie paper is concerned with a comparative study of observed sea 

 surface waves and recorded sea bottom pressure fluctuations „ 

 An empirical relationship is established between these factors . 

 It is stated that the average bottom wave period will be two 

 or more times that at the surface, depending on depth of

 Journal of Marine Research, Volo VII, NOo 1, April 15, 1948 » 



It is shown that for periodic surface gravity waves in a basin, 

 of great depth there exists a relationship allowing computation 

 of the mass of water transported by wave action. The various 

 concepts arising in the discussion are illustrated by a simple 

 dynamic analogue. 



"Deep Sea Photography," E. N. Harvey and E. R. Baylor, Journal of 

 Marine Research, Vol. VII , No. 1, April 15s 1948, 



A new type of camera and its lighting mechanism is described 

 for photographing organisms in the depths of the sea. The 

 apparatus has been used at depths of one half mile.
