Abstract
    Some results of two cruises in 1963 during the International Cooperative Investigations of the Tropical Atlantic (ICITA) are reported and interpreted. The average vertical distribution gives seston (particulate matter) values from 20 to 250 mg/m3, and albumin equivalents from 2 to 28 mg/m3. These amounts are considerably less than those observed in the northern part of the Atlantic Ocean. A great variation was observed, which could not always be explained by the general circulation. Accumulation at the surface was more obvious than concentrations of seston and plankton near or in the discontinuity layer of density. A stimulating influence of the equatorial undercurrent on productivity could not be established. In most areas the standing stock of micro-plankton was found to be low when compared to the biomass of larger plankton organisms.
