Currents 



Current data for the Cornfield Shoals disposal site are presented in 

 Figure G-4(a-d) and Table G-l . It is apparent from the speed-direction versus 

 time record that the current meter was not operating in a normal manner. The 

 data consists of spikes resulting from a misalignment of the tape head in the 

 recording device, however, the tidal component of the current can be resolved 

 from these data and is in fact presented in Table G-l.

The tidal component of the current at Cornfield Shoals has a kinetic energy 

 of 260 dynes /sec that is almost identical to the tidal energy at the New London
