1 1 -A "Wave Statistics for the Gulf of Mexico off Burrwocxl, 



Louisiana" by Charles L. Bretschneider and Roy D. Gaul 



Detailed statistical wave data for deep water, 96, 48, 

 24, cind 12-foot depths, based on hindcasts from synoptic 

 weather charts for the 3 years 1950, 1952, 1954, are 

 presented. Refraction coefficients and final wave 

 direction at those depths are also presented graphically 

 as a function of wave period and deep water wave direction.

II-B "Relative Efficiency of Beach Sampling Methods" by W. C. 



D Krumbein and H. A. Slack 



This is an extension to the work reported in Technical 

 Memorandum No. 50 in that this report presents the 

 results of several sampling experiments designed to 

 show more explicitly how estimates of certain beach 

 material properties may vary as a result of the sampling 

 plan adopted. A number of sampling designs applied to
