PREFACE 



This report is published to provide an analysis and discussion of the 

 Towed Oceanographic Data Aquisition System (TODAS) , developed for the 

 collection of information on nearshore currents and waves. The work was 

 carried out under the coastal processes research program of the U.S. Army 

 Coastal Engineering Research Center (CERC) . 



The report was prepared by Dr. P.G. Teleki, F.R. Musialowski, and 

 D.A. Prins under the supervision of Dr. David B. Duane, former Chief, 

 Geological Engineering Branch, and Dr. William R. James, his successor. 



Several people were instrumental in designing and constructing parts 

 of the TODAS: E.A. Maiolatesi, N.F. Lang, and B.W. Keebaugh of the 

 Instrumentation Branch, who designed the circuitry of the wave gage and 

 current meters; Dr. J.R. Weggel, L.L. Watkins, and CD. Puglia, who helped 

 with the design and modification of the sea sled; and G. Sine and other 

 members of the Hydrographic Survey Section, Survey Branch, U.S. Army 

 Engineer District, Los Angeles, whose enthusiastic participation in the 

 field experiments was much appreciated. The support and ideas of Dr. 

 Duane on the sea sled and experimentation are gratefully acknowledged.
