conciderrble prrt of the f^ifferonces between ctrtions in 

 the upper 250 motors. 



The following generrl picture mny, I believe, be 

 Scfely dravm from these df ta: 



1) The Voter in the Tongue of the Ocef.n below p-bout 

 300 meters is unmodified centrel i^.tlt.ntic wr.t''.:r. 



2) There is e salinity Kf.ximum rt rbout 200 meters 

 which mty be rs O..4O /oo higher thrn the t £t the surfrce. 



3) There is c salinity mrximurn ot cbout 50 meters 

 septrrted from th?.t o.t .200 meters by Wcter of lower 



ss Unity. 



4-) Below 300 meter the isopleth are so nearly 

 horizont&l that ? gradient current could not be relicbly 

 conputed. - 



5) The depth of the mixed Ic-yer rhd probably of the 

 Iryers of salinity mc.xinir rre sub.iect to verticcl tidfl

The vessel's cent--:rbo£:rd could not be lowered with- 

 out raising sril cs, in the ebsence of .• ny Itterp] pressure, 

 her movements could cruse en excessive pounding upon the 

 centerbor.rd logs. Consequently the leeway Hide in the pre- 

 velent SE wind mr.de it i^ipossible to. fo.rm Luy cccurfte 

 quantitative estimate of the surfcce current from the drift 

 of the vessel.
