A cximue.'ry of these data plus information on the speed of transport 

 during these periods is presented in Table 2o 



In generaip 't'he data on the direction of wind flow during the periods 

 that drift bottles were recovered from the Balanus and Albatross III 

 releases indicate that these bottles drifted against the" pfevaiTTng winds 

 for the interirals »overedo Conversely, the bottles recovered from the 

 O&i'jn releasss drifted with the prevailing winds o What, then;,, was the 

 elTect of the prevailing winds on the speed of transport? 



Drift bottles recovered from the Balanus and Albatross III releases 

 attained a maximum speed of 8o5 miles-per-day and 9o5 miles-per~day 

 respectively,, drifting against the prevailing winds; those recovered from 

 the Caryn releases attained a~maximxHn speed of but 6o5 miles=p8r=day 

 drifting 'ivith the prevailing winds o Drift bottles recovered from those 

 that had been released in the disposal area attained a maximum speed of 

 9o5 miles^per-day against the prevailing winds while those drifting with 

 the prevailing winds attained a maximica speed of but 2o3 miles-per=dayo 

 Could the presence or absence of drags have had any relation to tbds 

 effect? 



Of the 60 drift bottles recovered during the period 31 were 

 originally released with drags o An analysis of the data indicates that 

 bottles released with drags attained a greater speed of transporto These 

 average S«6 mileo-psr-day drifting with the prevailing winds while those 

 without j'ragc- averaged but lo7 miles-per-day* Bottles drifting against 

 the prevailing winds a-^reraged 5o5 miles-per-day with drags and 3o8 miles- 

 per^day witho\)t drags o 



The;^e anomalies m.ake it apparent that the direction of drift and 

 speed of tran.-;port of floating objects in the ocean off the New Jersey 

 coast was principally dsrendent upon the direction and rate of flov/ of the 

 prevailing currents _8 and that prevailing winds had little effect upon the 

 direction of drift© 



f-'arther studies on tne effect of wind on surface currents and drift 

 ■will be conducted in 1949 o 



SUMMARY AND CONCLUSIONS 



This; report i-s based upon the recorded findings of 60 drift bottles, 

 the returns from 489 releases » Drift bottle releases were made in an 

 area of the ocean off New Jersey and New York bounded on the 'Dast by 

 longitude 73"^ 00' Wo, and on the south by latitude 40^ 15« No, during July, 

 October J, and November 194So The release stations numbered 32., inclusive 

 of duplioabio:uo Ha;f of the bottles were simply stoppered and half were 

 stoppered and provided with 4-foot drags o These drags had the effect of
