Fifty miles off Cape May (Station 10072) readings were taken at 

 zero, four, and twenty-four fathoms, from 1-46 a.m. to 8-15 a.m., 

 the time of low water being 4 a.m. at Barnegat Inlet (Fig. 65). The 

 surface current ran southwest during the entire set, veering toward 

 the west (S. S. W. to W. by S.) with velocities ranging from .15 knot 

 at the beginning to .7 knot at the end, showing that the tide started 

 to flood shortly before we began work. The total drift was about

 through west, to W. W., N. the velocity ranging from .14 knot to .7 

 knot, the net drift 3 knots west, i. e., toward shore. The bottom 

 current at twenty-four fathoms veered irregularly from S. by E., 

 through S. W. west, and northwest to northeast, with velocities
