Figures 26 through 35 indicate the presence of two large counter 

 rotating gyres between the East Greenland and West Spitsbergen Currents. 

 In the extreme northeast portion of the survey region, there are 

 indications of a large anticyclonic gyre. Anticyclonic gyres also 

 appear to be present to the west of the portion of the East Greenland 

 Current shown on these charts. 



The dynamic topography charts derived from the 1964 EDISTO data 

 are, of course, subject to all of the normal and well known limitations 

 of this type of current analysis. 



6. Scatter Diagrams. 



Two micronutrient versus micronutrient (Figs. 36 and 37) and 

 three micronutrient versus temperature diagrams (Fig. 38) were constructed 

 in an attempt to further summarize and organize the micronutrient 

 data collected during this survey. The micronutrient versus temperature 

 diagrams were constructed using data from the upper 50 meters only. 

 The scatter diagrams will be discussed in more detail in the next 

 section. For the present, it will suffice to point out that some 

 of the scatter and overlap in these diagrams would not be present 

 if more precise analytical techniques had been available. The nitrate 

 values appear to be the least reliable micronutrient data, and some 

 points were not included in Figure 37 because their nitrate values 

 appeared to be suspiciously low.
