These returns, like the Caryn returns, also suggest that floating 

 objects released in the disposal area on November 1 were carried 

 southwesterly toward the New Jersey shore. 



NOTES ON THE INFLUENCE OF WIND AND DRAGS 



I « I I I I I I 



Flotsam or floating objects, such as the drift bottles used in this 

 experiment, are subject to winds directly through the exposed surface and 

 indirectly through winds which impel the surface layers and produce a drift 

 currento In order to detect any direct effect of wind the odd-numbered 

 bottles were supplied with drags to minimize the effect of wind-producad 

 currents on the speed of transport© 



With but one exception, — a bottle from the Caryn releases which 

 apparently drifted in a northwesterly direction -- the returns from the 

 1948 Balanus , Caryn , and Albatross III releases indicate a drift to the 

 south and westo This posed a question. Could the winds during the 

 periods between bottle releases and recoveries, and the presence or 

 absence of drags, have had any influence on their drift patterns or ^psed 

 of transport? 



Accordingly, readings of the wind force and direction in true compass 

 duadrants were determined at 6 hour intervals from Weather Bureatt charts 

 for the general area of release stations© The interval chosen for 

 recoveries from the Balanus releases was from July 27 through August 31 

 because it includes the date of first releases and the date by whicsh e.ll 

 the bottles still afloat had presumably drifted out of the area cf 

 immediate concerno The intervals chosen for the recoveries from the 

 Caryn and Albatros s III releases were October 22 through November 1, and 

 Novembe r 1 through November 6 respectively, the dates of first releases 

 and the dates by which 75 percent of the bottles had been recoveredo
