Summary.
Deep water along the northern ooast of South Amerioa.
Results of CICAR-investigations off the northern Southamerioan coast during autumn 1970 and spring 1971 are given, oonoerning the water below the 10oC-isotherm.

surfaoes indioate a motion of the Subantarotio Intermediate Water mass along the oontinental rise. This motion being far from regular gives an indioation of meandering along the boundary of an ocean current.The Upper and Middle Northatlantio Deepwater are olearly distinguishable by their oharaoteristios, i.e. salinity and oxygen maxima.
It is possible for some of the deepest reaohing stations to make a distinotion in the bottom water between water of Arotio and of Antarotio origin. Extrapolation yields an antarctic bottom water oontribution of about 40%, being in good agreement with literature.
