to heave to for several hours on account of weather. Oceanographic 

 work was resumed about 36 hours hxter and station 3070 was located 

 about 15 miles east-southeasterly of station 3009 although both sta- 

 tions were about equally distant from the coast aiul had about the 

 same depth of water. Average values of the two stations were used 

 in the construction of figure 30 and in the dynamic computations. 



The current situation existing during the post-season cruise is shown 

 in figure 31 where the dynamic topography of the surface relative to

2,000 decibars has been indicated. Since the stations of the survey 

 were disposed in the form of a single sectioji the current pattern cannot 

 be described with accuracy. However, figin-e 31 is of material help in 

 interpreting a velocity profile along this section and arriving at reliable 

 values for the volumes of flow of the Labrador and West Greenland 

 Currents. Volumes of flow, mean temperatures, and heat transfers 

 have been determined for 8 occupations of the section across the Lab- 

 rador Current off South Wolf Island and for 10 occupations of the West 

 Greenland Current off Cape Farewell. To facilitate comparison with 

 conditions found in other years these results are listed in table 4. 

 Except for the 1928 occupations by the Godthaab in May and the 

 Marion in July-September and except for the March 1935 occupation
