Summary
Seston amount in seas of the Mediterranean basin in the 0-100 m layer varied
within relatively large ranges and tended to decrease eastward.
In the south-western Atlantic the highest values for seston were obtained in
regions of the sub polar front and in adjacent waters. In the sub Antarctic water
mass the seston volume indices were 1.5 times as high as in warm waters of the
moderate zone of the southern hemisphere.
Copepods play the main part in the zooplankton groups occurring in the
southwestern Atlantic. Representatives of the epiplankton complex as well as
migrants Pleuromamma gracilis, Metridia lucens occurred throughout the whole
region under study. Pleuromamma robusta and Calanus simillimus dominating in
sub-Antarctic waters were replaced by Pleuromammo xiphias, P. abdominalis,
Calanus gracilis in subtropical water mass
