Summary.
The Occurrence of Subtropical Intermediate Water off the North coast of South America.
Oceanographic observations were made during Autumn 1970 and Spring 1971.
Special attention is ~iven to thes&inity maxlmum at about 100 m depth, resulting from the subtropical intermediate water possibly from both northern and southern origin. To obtain an insight in the spreading of these water types isentropic analysis accordinc to Montgomery has been used. It turns out that durinc both periods of investigation an anticyclonic gyre is present off Surinam, and during autumn 1970 also off Brazil. However, it is demonstrated that the Surinam and the Brazil gyres differ ln watertypes, based on their temperature-oxygen relation, according to Metcalf and Stalcup.
