Figure 53. Mean temperature (°C) versus mean salinity (%o) at standard depths (m) at oceanographic stations 

 taken by CGC CASTLE ROCK at Ocean Station ECHO, 14 July-4 August 1968 (20 stations). Hori- 

 zontal and vertical bars indicate limits of ±1 standard deviation of salinity and temperature. Solid-line and 

 dashed-hne envelopes indicate defined limits of North Atlantic Central Water (NACVV) and Upper North 



Atlantic Deep Water (UNADW).
