Table 2. — Area enclosed by border of Atlantic Current, 45th parallel, 49th meridian 

 and rhumb line 43° N., 49° W., 42° N.. 47° W., extended. Unit of area equals 

 10,000 square kilometers 



In adjusting the area for the effect of the Labrador Current we 

 have attempted to ehminate those sources of fluctuations in the 

 boundary which are not associated with the Gulf Stream system. 

 It is reasonable, then, to expect the adjusted area to be related to 

 other phenomena associated with the Gulf Stream system, such as 

 the difference in sea level between Bermuda and Charleston. A 

 preliminary examination of the data indicates that such a relation- 

 ship exists but further study will be given this subject which will be 

 reported on hi a future bulletin. 



In connection with this possible relationship between the fluctua- 

 tions in the boundary of the Atlantic Current in the vicinity of the 

 Grand Banks and the fluctuations in the difference in sea level be- 

 tween Bermuda and Charleston it is of interest to note another appar- 

 ent relationship between the latter fluctuations and the fluctuations 

 in the volume of flow of the West Greenland Current at Cape Fare- 

 well 1 year later. In Bulletin 29 of this series was shown a figure 

 illustrating the negative correlation between the departure from nor- 

 mal of the mean temperature and the volume of flow of the West 

 Greenland Current at this point, and covering the 10 occupations of 

 the Cape Farewell section occurring between 1928 and 1939. The 

 conclusion drawn was that fluctuations in volume of flow of the 

 West Greenland Current are largely the result of fluctuations in the 

 East Greenland Current rather than the Irminger Current. These 

 same 10 values of the volume of flow of the West Greenland Current
