1. Station positions for transects conducted on EVERGREEN 31-779, 



EASTWIND 31-987, and ROCKAWAY 31-1059. Inset chart shows 

 general location of area of investigation 4 



2. Vertical distribution of temperature (°C) and salinity (°/oo) in the upper 



300 m. Contour intervals 1C° and 0.1°/oo. Stations 1-18, 1-5 February 

 1966, EVERGREEN, 31-779. E indicates position of equator 5 



3. Vertical distribution of temperature (°C) and salinity (°/oo) in the 



upper 1800 m. Contour intervals 1C° (except in thermocline — shaded 

 area) and 0.25°/oo. Stations 1-18, 1-5 February 1966, EVERGREEN 

 31-779. E indicates position equator 6 



4. Vertical distribution of density (o-t, in g/1) . Stations 1-18, 1-5 February 



1966, EVERGREEN 31-779. Contour intervals 0.5 g/1 except in 

 pycnocline (shaded area) on 1800 m section. E indicates position of 

 equator 7 



5. Vertical distribution of temperature (°C) and salinity (°/oo) in the upper 



300 m. Contour intervals 1C° and 0.1°/oo. Stations 18-36, 5-9 February 

 1966, EVERGREEN 31-779. E indicates position of equator 8 



6. Vertical distribution of temperature (°C) and salinity (°/oo) in the upper 



1800 m. Contour intervals 1C° (except in thermocline — shaded area) 

 and 0.25°/oc. Stations 18-36, 5-9 February 1966, EVERGREEN 

 31-779. E indicates position of equator 9 



7. Vertical distribution of density (cr,, in g/1). Stations 18-36, 5-9 Feb- 



ruary 1966, EVERGREEN 31-779. Contour intervals 0.5 g/1 except 

 in pycnocline (shaded area) on 1800 m section. E indicates position 

 of equator 10
