general are weaker than usual, with greatest diurnal inequality. Speeds 
inerease with depth and average 1.8 knots at 15 meters (49 feet) and 
about 2.0 knots at 30 meters (98 feet). 
At the 5-meter depth (16 feet), between 0600 and 1700 on 26 March, 
the current had a tendency to rotate counterclockwise at a rate averaging 
10°T per hour but showed a general prevailing southwest flow with a 
mean speed of 0.4 knot. Between 1800,and 1300 of the following day , 
the current followed a definite rotary counterclockwise pattern and 
averaged about 22° per hour, completing a 360° cycle in about 17 hours. 
At 1300 a quick reversal occurred from southeast through north to north- 
west; thereafter, the counterclockwise rotary movement was again evident 
but at a slower rate, averaging about 10° per hour. 
At 15 meters there is a tendency for the current to rotate counter- 
clockwise but at a slower rate than at the surface, averaging about 12° 
per hour between 1800 on the 26th and 0100 on the 27th of March. Confused 
readings between 0200 and 0500 may indicate a fast change in the rotary 
pattern of flow or more likely a reversal that occurs more slowly, but 
about 10 hours sooner than at the surface. After 0600 a continuation 
of the counterclockwise rotary pattern is indicated but at a still slower 
rate, which averages about 7° per hour; after 1400 the data show a 
prevailing flow westward. 
At 30 meters (98 feet) the current shows a tendency to rotate 
counterclockwise, but the changes in direction are restricted to 
fluctuations between southwest and west. Indeterminate readings between 
0200 and 0600 correspond to those at 15 meters, and the decrease in 
speed may indicate the period when the tidal currents are subject to
