Description
Summary:CTD sections carried out in September 1998 are used to describe the water masses, geostrophic circulation and mass transport in the eastermmost branch of the Canary Current.The surface water mass (<600m) consists of North Atlantic Central Water (NACW) flowing south with a net mass transport of 2.3 x 10 (9)kg s(-1). A tongue of relatively fresh water, consisting of Antarctic Intermediate Eater (AAIW). was found approximately in the 600-1100 m depth layer. This tongue was 200 km wide, stretching from the African coast almost to Gran Canaria Island, and transported a net mass of 1.1 x 10 (9) Kg s(-1) northward. This system of currents is what constitutes the real eastem boundary current of the North Atlantic Subtropical Gyre.
