ABSTRACT 



This report contains a summary of progress on the "wave energy 

 loss" project through June 30^ 1952. 



The investigation thus far has consisted primarily of the planning 

 phase. 



It is anticipated that the second and third quarters be devoted 

 to the measurement phases of the programo The measurement phase will extend 

 through the season of hurricane activity in the Ciulf of Mexico o The analysis 

 phase of the program will overlap the measurement phase but will extend to 

 the end of the contract. 



Summary of Progress during the 1st Quarters 

 April 1, 1952 to June 30 1902 



During the first quarter the following major topics were of 



1« Instruments and auxiliary equipment 

 2o Plans for the investigation 

 3o Selection of personnel 



Instr.uraents and auxiliary equipment 



Three wave recarders and the necessary auxiliary equipment for the 

 operation of the wave reccsrders were received from the Beach Erosion Board, 

 These instruments were checked out in the field. Necessary repairs were 

 made and they are now in satisfactory operating condition. One of the 

 instruments has been installed permanently on the Pure Oil platform. Two 

 rain proof weather boxes made of marine plywood have bean built to house 

 each of the other two wave recordsrs,inverters^ timers, and storage 

 batteries. This is to aid in the efficiency of installing the other two 

 wave recorders at various temporary sites. 



Plans for the Investigation 



The general area of operation will be in the vicinity of the 

 Pure Oil platform. One wave recorder is installed permanently on the 

 Pure Oil platform^ the center point of operation. The other two wave 

 recorders will be placed en various surrounding sites, depending on 

 wave conditions and accessibility, 



A field party of two men vd.ll operate in this vicinity on 

 full time basis during the season of h-urricanes and other tropical storms. 

 During this period of operation time will permit the analysis of only 

 sample records ^ which will be used as a check on the reliability of the 

 operating proced'ore,
