mixed-water ellipse slightly overlapped those for Labrador Current 

 water and Atlantic Current water. 



The curves in figure 22 representing the conditions found in 1957 

 indicate that the Labrador Current water was denser than average down 

 to about 300 meters and lighter than average below this level. The 

 salinity was the determining factor and counteracted a slight opposite 

 effect of temperature anomalies. In the mixed water the 1957 obser- 

 vations showed denser than average water down to a depth of about 200 

 meters and lighter than average below that depth. Here both temper- 

 ature and salinity anomalies combined to produce the density anomalies. 

 In the Atlantic Current water densities down to about 200 meters were 

 close to average and below that level were lighter than average, with 

 the higher than average temperatures outweighing the effect of slightly 

 greater than average salinities.
