Abstract
Description
It is shown that phytoplankton of the equatorial Atlantic may produce organic substance under conditions of a ceased biogenic elements intake from without at the expense of their reserves in cells. Biogenic elements stock in phytoplankton in the upwelling regions is somewhat higher than in oligotrophic regions. On the basis of comparison of the field data and results of experiments with cultures, the phosphorus content in phytoplankton is calculated (percentage of dry mass). Phosphorus content in phytoplankton of oligotrophic regions amounts to 0,12% of dry mass (7% of maximum content), and in the upwelling region it is 0,19% of dry mass (10% of maximum content).
