20. ABSTRACT (Continue on reverse side It necessary and Identify by block number) 



A Towed Oceanographic Data Aquisition System (T0DAS) consisting of a towed 

 platform (sea sled) with current meters and a wave gage has been developed for 

 collection of information on nearshore currents and waves. Data acquired by the 

 sensors are telemetered to shore and digitally recorded. T0DAS is used for real- 

 time evaluation of flow characteristics between shore and a depth of 9.14 meters 

 (30 feet); this mobile battery-operated system can be used at remote locations. 

 The system has been used principally in two experimental designs: (a) Monitor- 

 ing the distribution of longshore currents in shore-normal profiles, and
