extending on a line running southwest to northeast, is down- 

 ward from southwest to northeast and is, therefore, indica- 

 tive of a current with a northerly component.* The remainder 

 of section A runs just west of north, and the slight slope of 

 the isotherms upward to the north is indicative of a weak east 

 component of the current across the section. 



Section B runs mainly in a west-east direction, and the 

 slope of the isotherms, downward from west to east, indicates 

 a northerly current. At the eastern edge of the section the 

 slope is reversed, indicating a southerly flow. Such a tem- 

 perature structure is evidence of a large eddy circulation. 

 The horizontal temperature structure at the surface, at 

 25 meters (82 feet), and at 40 meters (131 feet), is shown in 

 figures 17, 18, and 19 and further emphasizes the existence 

 of a clockwise eddy at about 55°N, 175°W. These features 

 will be discussed further in a later section. 



"A discussion of the relationship between thermal structure 

 and currents is given in The Oceans (ref. 13), p. 394.
